2024 Osstem World Meeting Seoul
elevates the company's global status
By Osstem Implant
Osstem Implant, a global dental
company, hosted its international
academic symposium in April, ‘2024
Osstem World Meeting Seoul (hereinafter, Osstem World Meeting
Seoul),’ inviting about 1,500 dental
professionals, including dentists.
The 'Osstem World Meeting,'
held on 27 and 28 April at Osstem
Implant’s headquarters and the
COEX exhibition hall in Korea, revolved around the theme 'Magic of
Leading Digital Dentistry.' The event
concluded with enthusiastic participation from dental industry stakeholders, including dentists and
dealer companies, from 56 countries
such as Germany, the Netherlands,
the United Arab Emirates, India,
Japan, Australia, and the United
States.
For those unable to attend the
event, the company provided real-time broadcasts through its expert broadcasting team, the online
education platform 'DenALL TV,'
and the YouTube channels of its
overseas subsidiaries, with simultaneous interpretation in English,
Chinese, Japanese, and Russian. Remarkably, the implant placement
procedures performed in the operating room at Osstem Implant’s
Seoul Central Research Institute
were broadcast live to the COEX
event. Additionally, the Q&A sessions between attendees and speakers at the COEX lecture hall were
fully broadcast, enabling remote
viewers to engage with the dynamic
discussions.
High satisfaction with hands-on
lectures using digital guides and
equipment
The ‘2024 Osstem World Meeting Seoul’ opened with hands-on
lectures and a stage performance by
K-POP stars on the ﬁrst day, culminating with seminar lectures and live
surgery on the ﬁnal day.
The hands-on practice sessions,
which are central to Osstem
Implant's clinical education curriculum, featured ﬁve topic-speciﬁc lec-

tures. These sessions were held for
approximately four hours, starting
at 9 a.m. at the Osstem Implant Central Research Center on 27 April.
Each lecture had 30 students enrolled, achieving a registration rate
of about 95% out of a total of
150 students.
The ‘Osstem World Meeting
Seoul’ hands-on training focused on
disseminating expertise to enhance
the convenience and accuracy of implant procedures using digital technology. Among the ﬁve hands-on
lectures, the know-how on utilizing
the ‘OneCAS Kit’, CBCT ‘T2’, and
3D printer ‘OneJet LCD’ garnered
signiﬁcant attention.
Dr. Nicolas Widmer from Switzerland provided an unforgettable clinical experience to students who used
the Osstem implant ‘OneCAS Kit’ for
the ﬁrst time under the lecture topic
‘Why Every Implantologist Falls in
Love with OneCAS Kit’. He highlighted the beneﬁts of the OneCAS Kit,
including: a sturdy template and sideopen structure that helps prevent
shaking even when drilling at high
speed during maxillary sinus lifting,
which has diﬃcult surgical conditions
due to the risk of perforation; the ability
to perform safe procedures on the
slope of the maxillary sinus using a
depth-adjustment stopper; and the
possibility of ﬂapless surgery without
an incision, to which the students responded with enthusiasm and amazement. Dr. Nicolas Widmer remarked,
“This innovative technology improves placement precision and
predictability while reducing the
possibility of invasiveness. As a result, not only does the convenience
of the procedure increase, but ultimately, patients receive the greatest
beneﬁt.”
In the hands-on lecture on ‘Minimally Invasive Treatment for Atrophic Maxillary Sinus,’ Dr. Brijesh Patel
from the United States shared insights on using CBCT 'T2' to aid in
establishing and predicting treatment plans for sinus membrane lifting.
In the 'Full Digital Approach from
Single to Full Arch Immediate Loading'

class, which had the largest number of
participants among the hands-on
practical lectures, Dr. Łukasz Zadrożny
from Poland demonstrated printing
temporary crowns and abutments with
a 3D printer and explained the process
for performing full arch immediate
loading.
Sharing tips on various uses
of ‘OneGuide,’ such as in edentulous and full mouth loss cases, as
well as maxillary aesthetic treatments
The event featured four sessions
and six lectures on 28 April. According to an Osstem Implant survey, the
most highly rated lectures were
'Achieving Immediacy in Every Case'
by Dr. Varo Boyer from the US in session 1 and 'Single-tooth Implant
Treatment in the Maxillary Aesthetic
Region: Tradition Meets Digital' by
Professor Marco Tallarico from Italy
in session 2.
In his lecture, Dr. Varo Boyer
shared insights on eﬃciently utilizing
Osstem Implant's digital equipment
and products to shorten the implant
treatment period.
He emphasized the ability of the
Osstem Implant CBCT ‘T2 Plus’ to
distinguish bone density from D1 to
D4 as a key advantage. He explained
that by knowing dental bone density
in advance, clinicians can select the
most appropriate drill diameter and
length and accurately calculate drilling depth. He elaborated that he can
demonstrate the utilization of the
'Medit i900' to display the scanned
image on a monitor, which can be
directly presented to the patient
during consultation. This process instills patients with a positive impression and a sense of trust in the practice, showcasing 'dentistry using the
latest digital technology' and 'eﬃcient management of patient medical records.'
Osstem Implant provided an expansive product exhibition hall

spanning approximately 991.74 m2
and conducted a model dental clinic
tour at the Seoul Central Research
Institute, providing 1,100 out of
1,500 attendees the opportunity to
acquaint themselves with the company's entire portfolio, including
ﬂagship oﬀerings. This exhibition
hall, showcasing over 10,000 diﬀerent dental products encompassing
implants, orthodontics, materials,
pharmaceuticals, and digital medical equipment, operates year-round
and has welcomed 4,300 visits from
dentists, academics, and government oﬃcials worldwide over the
past year.
Additionally, Osstem Implant organized a 'Product Exhibition Zone'
on the ﬁrst ﬂoor of 'COEX' in Seoul
for two days, signiﬁcantly enhancing
attendee satisfaction. This zone,
comprising 10 sections (Implant
Hands-on, GBR Hands-on, Digital
One Guide Hands-on, Video, Unit
Chair, Digital, Medicine, Hiossen,
Topla, Osstem Orthodontics), provided attendees who were unable to
participate in the ‘Hands On’ course
or tour the Central Research Institute’s exhibition hall with the chance
to explore Osstem Implant's wide
array of products, encompassing
both established favorites and
next-generation innovations.
Osstem impresses with the
latest K-POP stage by popular
idol groups and the traditional
pungo drum dance
On the eve of the event's ﬁrst
day, Osstem Implant delighted attendees with a diverse array of stage
performances, featuring popular
Korean idol groups, pop dance,
electronic DJ sets, and traditional
dance.
The Korean girl group STAYC
showcased the essence of the latest
K-POP trends, while Korean female
rock singer Seo Moon-tak delivered
a captivating performance, high-

lighting her decades of stage experience and exceptional vocal talents.
Of note was her rendition of "Buk
(drum)," a traditional Korean percussion instrument, which stirred applause as it vividly conveyed the enduring excitement and cultural ﬂair
of Korea. Culminating the evening,
1,500 attendees enjoyed freely
dancing to the beats of the electronic DJ.

Can teeth whitening be harmful?
By Ultradent Products
They’re all too common questions: Can whitening harm teeth? If
so, what’s the least harmful teeth
whitening? Can too much whitening
damage the teeth? Are there safe
teeth whitening products that don’t
harm teeth at all?
Teeth, and more speciﬁcally,
smiles, are one of the most unique,
inimitable things we possess, and
they deserve protection.
That said, so many yearn for
more conﬁdence in showing their
smile to the world. Teeth whitening
deﬁnitely helps—especially when
years of food, wine, coﬀee, and/or
tobacco stains have taken their toll.
Stubborn yellow or brown staining can prove diﬃcult to simply
“brush away.” Yes, the right whitening toothpaste with a gentle amount
of grit can buﬀ away surface discoloration, but often, the problem lies
deeper within the enamel. Factors
like aging and genetics contribute to
tooth shade too.
Thing you should know
When it comes to teeth whitening, it’s important to take several
factors into consideration. After all,
you want to choose a whitening
product that’s both safe and eﬀective. In fact, many potential consum-

ers shy away from teeth whitening
out of the fear of decalciﬁcation or
tooth enamel damage, which is entirely preventable.

ing until the patient’s enamel shade
matches the color of the whites of
their eyes, then stopping until further whitening is needed.

Choosing a safe whitening
product
Dr. Dan Fischer, founder of Ultradent Products, Inc., as well as
Opalescence Whitening products
(the #1 professional teeth whitening
brand in the world), has always adhered to the following science: “It all
comes down to the pH of the whitening product, because the reality is
that tooth decalciﬁcation is caused
by exposure to acidity—or a low pH
in the mouth.”
Dr. Fischer adds, “For this reason, all Opalescence teeth whitening products feature a nearly neutral
pH that closely matches the pH of
the patient’s mouth.”
This prevents harm and decalciﬁcation of tooth enamel, allowing
patients to whiten their teeth and
maintain a healthy smile. Furthermore, while an excess of anything
isn’t always the best option, if patients choose a safe, studied, and effective teeth whitening product like
Opalescence whitening (under the
supervision of their dentist), they
can rest assured the product won’t
damage their teeth. In fact, most esthetic dentists recommend whiten-

What about DIY teeth whitening?
Are the active ingredients in
teeth whitening (e.g., hydrogen peroxide or carbamide peroxide) dangerous, and is one ingredient preferable to the other? What about
“natural” ingredients like charcoal or
baking soda for teeth whitening?
While trendy, whitening teeth
with ingredients found at home or
over-the-counter like charcoal, baking soda may remove surface staining, but can’t lighten the shade of
teeth. Additionally, patients using
such ingredients run the risk of
abrading their tooth enamel, causing long-term damage and discoloration.
Studied, proven, safe teeth
whitening
The only substance proven to
whiten tooth enamel color is peroxide—whether it be carbamide peroxide or hydrogen peroxide, with
both yielding high quality results.1
Both amounts of hydrogen peroxide
and carbamide peroxide, depending on the product, are in are commonly found in and processed by

the body, and are considered safe
and non-toxic to use on the teeth. 2
Dentists can help determine the
right whitening product for their patient’s unique case, as Ultradent’s
Opalescence teeth whitening systems oﬀer solutions featuring both
carbamide peroxide and hydrogen
peroxide.
There are also methods and kits
to accommodate every lifestyle.
These include Opalescence Go preﬁlled disposable whitening trays,
Opalescence PF custom teeth whitening, and the Opalescence Boost
in-oﬃce whitening system.

The new Synea Power Edition:
For processing the hardest materials
By W&H
The new W&H high-speed contra-angle handpieces have been
specially designed for the processing and removal of high-strength
ceramic materials such as zirconia.
Oﬀering a particularly robust design, additional torque and stable
removal rate, the new Synea Power
Edition is the ideal solution for
highly demanding applications
such as crown and bridge removal.
Ceramic materials such as zirconia are being used more and
more frequently in modern, restorative dentistry. However, removing
zirconia restorations with conventional contra-angle handpieces is a
challenging and lengthy procedure. Attempts to do so often result in damage to the burs and delays in treatment, which can be
frustrating for dentists and their
patients. With the new Synea Power
Edition, W&H has introduced a cutting-edge solution and the perfect
addition to existing high-speed
handpieces in dental practice. “It’s

a safe contra-angle handpiece for
crown or bridge removal that also
protects existing contra-angle
handpieces”, says Dr Florian Krekel
about the new Synea Power Edition.
High-performance
contra-angle handpieces for highstrength materials
Thanks to the modiﬁed transmission ratio, the extra strong
Synea Power Edition contra-angle
handpieces ensure optimum bur
speed and provide the extra torque
required to process hard materials
eﬃciently. The capacity to remove
the tooth structure more eﬃciently
at the same surface pressure prevents heavy wear to the bur, as well
as reducing the risk of thermal
damage to the teeth. The service
life of these contra-angle handpieces is extended by at least 20%
compared to standard transmission instruments, as they are less
susceptible to mechanical fault.
Another contributing factor is
the newly developed extra-stable

chucking system from W&H. With a
20 % increase in chucking force, the
innovative system is tailor-made
for applications involving highstrength materials. “I am thrilled
with the chucking system; it makes
for a better workﬂow when it comes
to replacing burs”, says Dr Klaus
Kohlpaintner. The new push-button design also makes replacing
the burs easier, because the loads
are distributed more evenly. With
an ergonomic head design for better bur guidance, as well as a
multi-nozzle spray with high water
ﬂow for optimum cooling of the
treatment site, the impressive new
Synea Power Edition is a convincing
and reliable overall package.
Three is the magic number
With the special Synea 900 series, W&H has developed three
high-speed handpieces. The WK900 LT joins the premium line of the
Synea series, while the WG 900 A
and the WG-900 LT are excellent
additions to the Synea Fusion portfolio.

Monolithic multilayer zirconia crowns
in the aesthetic zone
By Dr Wissam Dirawi, Sweden
Introduction
During the last decade, zirconia
has increasingly become established as the material of choice in
prosthodontics. Its excellent mechanical and inert properties are
the main reason for this trend.
Since the introduction of multilayered zirconia blanks more than ten
years ago, the material’s optical
properties have been improved
dramatically. The multilayered zirconia used nowadays (e.g. KATANA
Zirconia YML, Kuraray Noritake
Dental) oﬀers wellbalanced mechanical properties, translucency
and colour. It allows dental technicians all over the world to produce
aesthetic full-contour restorations
that only require staining.
Even in the anterior region,
stained monolithic resto rations
may be an option. Factors such as
the age of the patient, the internal
colour structure of the adjacent
dentition, the number of teeth to
be restored (one versus four or all
six maxillary anterior teeth), the
aesthetic demands of the patient
and ﬁnancial aspects should be
taken into account in the material
selection process. In the case described in this article, full-contour
zirconia was selected for several
reasons.
Background
The 71-year-old female patient
presented in the clinic owing to
aesthetic concerns in the maxillary
anterior region. Her oral hygiene
was good, and she was a nonsmoker. Infraposition of the existing implant-based crown (Brånemark regular platform, Nobel Biocare) in the position of the right
central incisor was evident. Moreover, gingival retraction was observed on the maxillary right lateral
incisor, and the left lateral incisor
(tooth #22) had a major composite

ﬁlling with discoloration (Figs. 1–3).
The patient expressed the desire to
have the gingival margin diﬀerences adjusted and the four maxillary incisors restored with ceramic
crowns for optimal aesthetics.
Material selection
Owing to the decision to restore all four anterior incisors,
monolithic zirconia was deemed a
suitable material option. It would
allow the team to obtain the desired results within the ﬁnancial requirements. In order to meet the
aesthetic demands of the patient,
provide for the required mechanical properties and allow for proper
masking of the underlying structures, KATANA Zirconia YML was
selected. It oﬀers colour, translucency and ﬂexural strength gradation throughout the multilayered
blank.
Treatment procedure: From
preparation to temporisation
In order to design the indirect
restorations, a digital impression
was taken with an intra-oral scanner, and the data was transferred to
the dental laboratory (Teknodont,
Sweden). The laboratory created a
digital wax-up. After the patient’s
approval, a matrix was produced
and sent to the clinic. The old restorations were removed and the
three maxillary incisors (all but the
one replaced by an implant) prepared for complete crowns. A healing abutment was placed on the implant and a temporary bridge produced chairside from Protemp 4
temporisation material (3M ESPE) in
Shade A3 using the matrix (Fig. 4).
Subsequently, a gingivectomy was
carried out with a ceramic bur
(KT.314.016 CeraTip, Komet) at the
buccal aspect of teeth #21 and 22.
After the patient’s approval of
the aesthetics, phonetics and function of the temporary restoration,
the situation was captured with an

intra-oral scanner again. This allowed the team to duplicate the shape of the restoration. Based on the data
acquired, two pairs of splinted temporary crowns were
milled from PMMA (HUGE Multilayer PMMA, HUGE

Dental) in Shade A3 in the laboratory (Figs. 5–7). They
were placed to allow the patient to further evaluate the
appearance and function for several weeks (Figs. 8–10).

The patient was happy with the
phonetics, function and appearance of the crowns, noting only
that they were slightly too bright in
comparison with the adjacent
teeth, and she approved the shape
for the production of the permanent restorations.
Final restoration: Production
and cementation
Based on the data set of the
temporary restorations, four sepa-

rate crowns—one for the implant
and three for the teeth—were designed in full contour. Without any
anatomical reduction, the restorations were milled from KATANA
Zirconia YML. Based on the evaluation of the temporary restorations,
the shade selected this time was
Shade A3.5. CERABIEN ZR FC Paste
Stain (Kuraray Noritake Dental) was
used for external staining and glazing of the surface. The laboratory
also cemented the implant-based

crown to the gold-shaded titanium
abutment (Elos Medtech) with PANAVIA V5 (Kuraray Noritake Dental) in the shade Opaque for an improved masking eﬀect (Fig. 11). In
the oﬃce, the abutment–crown
was screwed on to the implant and
the screw access hole closed with
composite, and the three toothbased crowns were then placed
using PANAVIA SA Cement Universal (Figs. 12–15).

Conclusion
Multilayered zirconia is a suitable material for many clinical situations. Owing to the availability of
highly translucent multilayered
blanks, it is now possible to produce aesthetic outcomes even
when using the material monolithically, and this is true not only in the
posterior region but in the aesthetic zone in some cases too. The
present case demonstrated that

Personal Oral Protocol concept
By Eric Berger, France
In the ﬁeld of dental prosthetics, digital communication has undergone a major revolution in recent years, transforming how dental technicians interact with dentists, laboratories and patients.
Thanks to technological advancements and innovative digital tools,
digital communication in dental
prosthetics has im proved treatment eﬃciency and the accuracy
and quality of the ﬁnal results. The
Personal Oral Protocol (POP) in
dental prosthetics employs digital
communication tools to personalise prosthetic treatment based on
the speciﬁc needs of each patient.
This article discusses the POP
approach, describing its advantages, the information required
and the process, and explores the
imme diate future of digital communication and developmental
trends in the ﬁeld of dental prosthetics. It is important to note that
the POP protocol may vary based
on the speciﬁc needs of each patient.
Advantages of the POP
Personalisation of treatment
The most obvious advantage of
the POP is the personali sation of
prosthetic treatment. Each patient
has unique needs, aesthetic preferences and objectives regarding his
or her dental prostheses. The POP
allows dental professionals to create customised solutions for each
individual, taking into account his
or her anatomical characteristics,
facial morphology and aesthetic
preferences.
Improved patient experience
Digital communication has a
positive impact on the overall patient experience in dental prosthetics. CAD allows pa tients to visualise
their future smile and actively participate in the aesthetic and functional choices for their prostheses.
This involvement strengthens pa-

tients’ conﬁdence in the treatment
and increases their longterm satisfaction.
Better aesthetics
The POP aims to create prostheses that perfectly harmonise
with the patient’s appearance and
smile. By considering individual facial features, tooth colour and
other aesthetic elements, pros theses made using the POP oﬀer a
more natural and aesthetic result.
Functional improvement
In addition to aesthetics, the
POP takes into account the masticatory and phonetic function of the
patient. A customised prosthesis
provides better occlusion and articulation, improving masticatory

function and the patient’s quality
of life.
Optimisation of the design process
The POP uses advanced digital
tools such as CAD and 3D printing
to facilitate the design and fabrication process of prostheses. This ensures more precise results and reduces manufacturing times.
Adaptability to changes
The POP allows for treatment
adjustments based on changes in
the patient’s oral health. If adjustments are needed over time, the
personalised treatment facilitates
modifying the prostheses to meet
the patient’s evolving needs.

Necessary information
Detailed prescription
A precise prescription must be
provided by the dentist, clearly describing the patient’s aesthetic expectations and technical speciﬁcations for the prosthesis.
Accurate digital impressions
Highquality digital impressions
of the patient’s oral cavity must be
taken to obtain an accurate model
of the teeth and gingivae.
Objective colour measurement
A spectrophotometer is used to
objectively measure the colour of
the patient’s teeth. Unlike visual
observation, which can be subject
to subjective interpretations, the
spectrophotometer provides pre-

cise quantitative data, ensuring an
accurate match between the colour
of the prosthesis and that of the
patient’s natural teeth.
Comparison with reference
samples
The spectrophotometer compares the measured colour with
reference samples, such as standardised shade guides, to ﬁnd the
closest match to the patient’s natural tooth colour. This ensures an accurate match with the colour desired by the patient or prescribed
by the dentist.
Intra-oral photographs
Detailed intraoral photographs
of the patient can be useful for the
dental technician to better understand the morphology and colour
of the patient’s teeth.
Smile line indications
The dentist can indicate the
smile line, that is, the alignment
and desired position of the edges
of the teeth when smiling.

Occlusal dynamics data
Information on occlusion is essential for a prosthesis that integrates perfectly with the teeth.
Materials and techniques
The dentist and dental technician should discuss the materials
and techniques to be used.

Use of 3D and 4D smile design-

Smile designers perform a
comprehensive aesthetic analysis
of the patient’s face, taking into account facial shape, facial features,
lips, eye colour and other elements.
This holistic approach allows for
the design of prostheses that perfectly harmonise with the patient’s
overall appearance.
Personalised design
Using CAD tools and 3D printing, smile designers can create digital models of personalised prostheses based on the patients’ aesthetic preferences. These models
enable visualisation of the ﬁnal result before manufacturing, allowing for adjustments if necessary.

Fig. 10: Mandibular dynamics in inLab CAD SW 22.0. Fig. 11: Complete prosthetic simulation.

In-depth case analysis
The digital data collected is
thoroughly analysed by the dental
professionals. They use specially
developed CAD soft ware for the
POP, allowing them to visualise the
data in 3D and gain a detailed understanding of the patient case.

Patient involvement
Smile designers actively involve
patients in the design process by
consulting them on their aesthetic
preferences and considering their
speciﬁc wishes. This collaborative
approach gives patients a sense of
control over their treatment and
conﬁdence in their new smile.

Precise and personalised design
Using digital data and advanced digital tools, the dental
technician creates a customised
prosthesis for the patient. He or she
can precisely adjust the shape, size,
colour and occlusion of the prosthesis based on the patient’s individual characteristics and aesthetic
preferences.

Patient’s smile simulations before treatment
Smile designers use advanced
software to simulate the appear
ance of the smile after prosthetic
treatment. These simulations allow
the patient to see the potential result before making a deﬁnitive decision, thereby increasing treatment compliance.

Simulation and patient validation
Once the initial design has been
completed, a digital simulation can
be performed to show the patient
what the ﬁnal result is expected to
look like. This allows the patient to
validate the design and give approval before the physical fabrication of the prosthesis.

Communication between the
dentist and dental technician
Smile designers act as mediators between the dentist and dental technician, communicating essential information for the prosthesis realisation. This eﬀective communication ensures that the
patient’s aesthetic expectations are
met.

Precise fabrication using 3Dprinting
The optimised digital data is
used to guide the 3D-printing process of the prosthesis. This technology allows for the manufacture of
prostheses with high precision,
providing a perfect ﬁt and better
aesthetics.

Optimisation of function and
aesthetics
Smile designers aim to balance
masticatory function with the aesthetics of the smile. They ensure
that prostheses are not only beautiful but also functional and comfortable for the patient.

Follow-up
and
prosthesis
adaptability
Digital data is also useful for
patient follow-up and prosthesis
adaptability over time. If adjustments are necessary, digital data
allows the dental professional to
quickly make the required modiﬁcations.

Chronological process
Precise data collection
The POP begins with the precise collection of patient data, including digital dental impressions,
intraoral and extraoral photographs, and information about the
patient’s aesthetic preferences and
speciﬁc needs. This digital data
provides a comprehensive basis for
the design of the prosthesis.

Patient data back-up
The POP allows for the backup
of the patient’s digital data, making
it easier to create replacement
prostheses if needed. The data can
be used as a reference for future
prosthetic interventions.

Fig. 12: 2D, 3D and 4D imaging combined in DentalCAD 3.1 Rijeka (exocad). Fig. 13: Face scan in exocad 3.1 Rijeka.

Summary
In summary, the POP optimises
the employment of digital data in
dental prosthetics, allowing for precise data collec tion, personalised
and accurate design, patient validation, high-quality 3D-printingbased fabrication, and longterm followup and prosthesis adaptability.
By closely collaborat ing and providing comprehensive information,
the dentist and dental technician
can improve the quality, eﬃciency
and overall satisfaction of prosthetic
treatments for patients.

The immediate future:
Collaborative telecommunication—POP 2.0
Digital communication facilitates collaboration between dental
technicians, dentists and laboratories. Digital ﬁles of prostheses can
be instantly shared via secure platforms, allowing the diﬀerent actors
involved in the process to work
synchronously and eﬃciently, even
if they are geographically distant.
Developmental trends
Real-time communication
Collaborative telecommunication enables realtime ex change,
meaning participants can communicate instantly through messaging
or voice or video calls. This real
time communication fosters quick
problemsolving and informed
decisionmaking, leading to better
coordi nation in planning and executing prosthetic treat ments.

the laboratory and dental oﬃce (Drs Christian Moussally and Ty Vallée).

Asynchronous communication
In addition to realtime communication, collaborative tele communication facilitates asynchronous communication. This allows
users to share information and collaborate at their own pace.
File and document sharing
Collaborative telecommunication tools allow for easy sharing of
ﬁles and other digital resources.
This enables members to work together on projects, review documents and access relevant information.
Online collaboration tools
Collaborative telecommunication often includes online collaboration tools, such as project management plat forms, virtual whiteboards and shared storage spaces,
which facilitate activity coordination and information visualisation.
Multiplatform accessibility
Collaborative telecommunication solutions are generally accessible on various platforms, including desktop computers, mobile devices and tablets, allowing users to
collaborate anytime and anywhere.
Security and privacy
Collaborative telecommunication prioritises the security and
conﬁdentiality of data exchanged
between users. Security measures
are often put in place to protect
sensitive information.

Transforming dental care for
children: Insights from
Align Technology’s Middle East events
By Dental Tribune MEA

Can you share some of the innovations that enhance the treatment experience and outcome for
growing patients and how these
can be implemented into practices?

Dental Tribune MEA recently
had an opportunity to speak with
Markus Sebastian, Senior Vice
President EEMA at Align Technology, to discuss the company’s innovative eﬀorts in pediatric orthodontics. In the interview, Sebastian
delves into the Growing Patient
Roadshow taking place across the
Middle East, the importance of tailored dental care for children and
teenagers, and the latest advancements in digital dentistry that are
transforming treatment experiences and outcomes for younger
patients.

Align Technology recently
hosted its Growing Patient Roadshow across the Middle East,
with further events to come later
this year - can you tell us more
about the events and what attendees can expect to take away
from the sessions?

The Align Growing Patient
Roadshow is a series of events that
take place throughout the year
across the Middle East, in the Kingdom of Saudi Arabia, Kuwait, and
Dubai. The idea behind this series is
to bring doctors together from all
over the region along with international Invisalign speakers to delve
deep into the topic of treating
‘growing patients’ (children and
teenagers) and discuss the many
nuances and considerations that
set these patients apart from
adults. It has been designed as a
four-stage series, guiding doctors
through the journey of building
their conﬁdence in treating growing patients, accelerating their
growing patient practice using
Align Digital workﬂows, enhancing
clinical outcomes for growing patient cases, and ﬁnally, mastering
growing patient treatments. We recently held the second installment

which saw over 200 Invisalign providers attend and engage with
guest speakers, gaining a deeper
understanding of practical applications and integrating the most eﬃcient workﬂows into their practice.
We’re already looking forward to
the next installment in September,
with the series concluding in December this year with guest speaker
Dr.Sandra Tai.

Why are growing patients a
key focal area for Align Technology, and what are the main considerations for this demographic
when delivering dental care?

The orthodontic treatment of
growing patients is important for
children’s overall health and
well-being and to help avoid more
complex dental problems in the future, and yet this can be an area of
treatment met with uncertainty
from both practitioners and parents. Our recent whitepaper research showed under 19’s make up
a signiﬁcant portion of the population in the region, 39% in KSA and
30% in UAE, demonstrating the importance of opening up conversation channels around orthodontic
treatment for younger patients and
extending education to our providers that empowers them to approach each clear aligner treatment conﬁdently and seamlessly.
Through our recent white paper research and events like the Growing
Patient Roadshow, we aim to elevate the level of dental care for children in the Middle East while also
encouraging parents to become an
integral part of the process and really understand the beneﬁts and
challenges that can be expected on
a treatment journey. When personalizing a treatment plan for younger
patients using the Invisalign System, we’re able to prioritize their
comfort, daily oral hygiene, and
conﬁdence without sacriﬁcing their
lifestyle, hobbies, and eating habits.

There are a number of innovations already integrated into the
treatment journey that can have a
positive impact on the patient's experience and the practice workﬂow. Some of the treatment innovations are designed speciﬁcally
for younger patients, such as Invisalign First clear aligners, which
address a range of orthodontic issues in younger children, such as
arch development and dental expansion. Invisalign First aligners are
tailored to accommodate the
unique dental needs of children,
providing eﬀective early intervention and encouraging long-term
dental health. Our other innovations can enhance the treatment
experience of younger patients
while also being used across adult
patient treatment plans – creating
further eﬃciency and a more
streamlined practice workﬂow for
practitioners. The iTero intraoral
scanner, for example, allows for
precise, real-time 3D digital scans,
negating the need for uncomfortable impressions. This system is
fully integrated with our Align
Digital Platform. Finally, the My Invisalign app has been designed to
help practices support patients in
every step of their Invisalign journey, from making the decision to
start treatment to switching to
their last aligner in treatment. The
user-friendly interface helps engage younger patients and maintain their motivation throughout
the duration of treatment.

As digital dentistry evolves,
especially in the Middle East,
how do you envision the wider
adoption of new innovations and
techniques into practices looking
to digitize their workﬂow?

The widespread adoption of
digital dentistry, tech-based tools,
and upgraded techniques hinges
on several factors. The region is
seeing an increasing awareness
and willingness among dental professionals as the beneﬁts observed
in practice eﬃciency and clinical
outcomes are being acknowledged. Systems that are able to be
seamlessly integrated, like the
Align Digital Platform and tools
such as the iTero intraoral scanner,
can facilitate this acceptance
through the eﬃciency and precision they oﬀer. Education and training are also crucial components of
this transition, which is why we

place such a strong emphasis on
providing continuous and accessible knowledge through events, be
it through our masterclasses, roadshows, and webinars, to equip dental professionals with the knowledge and practical application of
years of research.

Considering the integral role
of orthodontists in interceptive
orthodontics for growing patients, how does Align Technology ensure that its evolving technologies continue to support and
enhance the expertise of these
professionals rather than replace
it?

Through the development of
dental innovations and our continued work to enhance digital dentistry across the Middle East, our
aim is really to support and enhance the expertise of orthodontists rather than replace their skills
with technology. Our innovations,
such as the Invisalign System and
iTero scanners, are designed to
augment practitioners' skills. We
focus on providing tools that improve diagnostic accuracy, treatment planning, and patient outcomes, enabling professionals to
deliver superior care and run a
more eﬃcient dental practice. Prioritizing comprehensive training
and education ensures dental professionals are proﬁcient in using
our technologies, empowering
practitioners to integrate these innovations seamlessly into their
practice, ultimately enhancing their
expertise and maintaining their
pivotal role in patient care.

With many families planning
to travel over the summer, how
can they ensure that their child's
Invisalign treatment is not affected by being away from their
orthodontists over the school
holiday/summer period?

Peak travel season for Middle
East-based families doesn’t have to
mean a pause in any ongoing orthodontic treatment. Before traveling, parents can schedule a
check-up with the orthodontist to
receive any necessary aligner adjustments or new sets for the travel
duration. Many Invisalign providers
in the region oﬀer virtual consultations and check-ins, which help ensure the treatment plan remains on
track if it’s an extensive period of
travel. Using the My Invisalign app
can also help track progress, schedule reminders to move onto a new
set of aligners, upload progress images, and stay in touch with the orthodontist.

INTERVIEW

Dental Tribune Middle East & Africa Edition | 04/2024

Focusing on education for
better dentistry
By Dr Dobrina Mollova,
Dental Tribune MEA
Simon Campion spoke with
DTMEA at the 2024 DS World Dubai
earlier this year to discuss insights
gained from his ﬁrst year as President and CEO of Dentsply Sirona.

Reﬂecting on your ﬁrst two
years as president and CEO, can
you share some of the highlights
and challenges?

Let’s start with the highlights.
We have a great group of people at
Dentsply Sirona – 15,000 employees who are committed to making
the company more eﬀective and to
continue to deliver great solutions
for our customers.
Another highlight is the comprehensive product portfolio assessment we completed in late
summer last year in which we surveyed 2,000 dental professionals in
the US, Germany and China. From
that survey, we conﬁrmed that we
have no meaningful product gaps.
The third highlight has been
the quality of our clinical education
oﬀering. We commit a lot of resources to providing great education, and we know that it makes a
diﬀerence to the practice of dentistry. In the past 18 months, we
held DS World events in Dubai, Las
Vegas, Italy, and Spain. Our Asia Paciﬁc team held there second DS
World Dubai and we are preparing
for our ﬁrst DS World Asia Paciﬁc in
Japan this year. Additionally, we will
also have a DS World in Sao Paolo,
Brazil.
Dentsply Sirona went through
quite some changes before I became the CEO. My early priorities
were continuing to improve our efﬁciency and agility as an organization. We built on work that was already in progress and introduced a
new operating model with a simpliﬁed structure. We also enhanced
the customer experience by leveraging digital solutions. And we
have elevated even further the role
of quality in the organisation.
Dentsply Sirona has a history of
innovation over 130 years strong.
We’ve steadily worked to develop
solutions that meet the needs of
our customers and help them ad-

vance conﬁdently as dentistry
evolves and transforms. That has
always been done with a commitment to quality and continuous improvement.

Would you please share some
key achievements or updates
made to the company’s strategy
since your leadership transition?
How does Dentsply Sirona plan to
navigate the upcoming industry
trends?

There are lot of opportunities,
especially when it comes to digital
dentistry. We have been ﬁrst to the
market when it comes to intraoral
scanners, and we’ve got Primemill
and Primeprint and now DS Core,
—and focus on supporting dentist
transitioning their practices into

digital workﬂows as still most dentists globally don’t have a scanner.
This is one of the reasons why we
invest in education, and that’s why
we drive the beneﬁts of eﬃciency
and improved workﬂows. We think
that DS Core is going to be very
meaningful to the future of dentistry.
We launched DS Core in May of
2022 and since its launch, we have
released numerous value- adding
features, workﬂows and services
for our users. For example, we
launched the communication canvas and the SureSmile Simulator in
September last year. We believe we
have only scratched the surface of
DS Core’s capabilities, and we’ve
seen impactful improvement in the
adoption of DS Core every time

We’re trying not to break it;
we’re trying to improve it.

we’ve rolled out new clinical functionality.
Another important trend has to
do with the demographics of dentistry. Women make up an increasing share of dental professionals
and a majority of dental students in
many countries. It's important that
we continue to support women in
dentistry, listen to their speciﬁc
needs, and work hard to take those
needs into our development process.
Also, there is a lot of potential
for our company and for our industry overall to improve the delivery
of dental care globally, making it
more accessible, especially to those
who have traditionally faced barriers.

Earlier this year, Newsweek
named Dentsply Sirona one of
America’s Greenest Companies.
Three years ago, the company
launched its sustainability strategy, “BEYOND: Taking action for
a brighter world”. What progress
has been made over the past year
in implementing sustainable
practices within the company
and industry? Can you share updates on the Sustainability Educational Curriculum and its impact on dental professionals?
How is Dentsply Sirona contrib-

uting to the broader sustainability goals of the dental industry?

Our sustainability strategy is
fundamental to our mission of
transforming dentistry and improving oral health globally. The
commitment to it begins at the top
with our board of directors, and it
goes through our entire organisation. We have multiple goals
around it—healthy planet, healthy
smiles, healthy business—and
we’re convinced we are on the right
path. So far, we are making important progress on the goals that
we’ve set out to achieve. For example, we’ve already achieved our
2025 goal for reducing indirect
emissions that are part of our
Scope 1 & 2 targets. We’re committed to reaching net-zero carbon
emissions, and our actions were
recognised, as you mentioned, by
Newsweek’s ranking.
The work that we do with Smile
Train, helping to treat children with
clefts, is extremely important to us.
We’ve supported over 2,700 surgeries through this partnership. It
has transformed these children’s
lives. We had a fantastic meeting in
São Paulo last year in October
where we met some of our partners
who are helping to treat the indig► Page 21

enous population in the Brazilian
rainforest. For this, a Primescan AC
was transported up the Amazon on
a canoe to help the indigenous
communities access oral healthcare.

How has Dentsply Sirona responded to the challenges faced
by the dental industry, including
those related to the ongoing
global situation?

Let me start with something related to your last question about
sustainability. We have demonstrated our commitment to achieving and even exceeding our sustainability goals with respect to
healthy planet, healthy smiles and
healthy business, which is very important for our planet, for our employees and for our partners
around the world. We have also
demonstrated our commitment to
improving eﬀectiveness and eﬃciency of dental treatment through
digital dentistry.
As a company, we are trying to
be more eﬃcient internally, in our
systems and through our investments in Dentsply Sirona’s infrastructure. Additionally, we think
that clinical education plays an incredibly important role in dentistry,
in addressing future challenges,
and in improving access to oral
healthcare globally. We do in-person events like DS World in Las
Vegas, in Madrid, in Italy, in Dubai
and later in the year in Asia Paciﬁc
to meet clinical education needs,
and we’re also expanding our education that’s available online.
So, we are enhancing our reach
globally and improving access to
great dental curricula and training
by moving it online to support dental professionals. In the long term
we’re going to grow our company
and expand our reach through clinical education, improving access
and bringing new technologies to
bear in the digital space and by
bringing existing technologies into
new markets. For example, we have
lunched SureSmile clear aligners in
Brazil earlier this year.
There are a lot of challenges in
the global environment of our industry, but we are trying to navigate them to the best of our ability.
I think the decisions that we’ve
made and the investments we are
making will continue to help us
navigate these challenges.

You previously mentioned a
focus on providing a unique customer experience. How has the
company enhanced its customer
support and engagement strategies? Are there any new initiatives aimed at supporting customers in their practice growth?

I think we have become more
customer-centric since I arrived. An
example of this is the quarterly surveys we now do. I have already
mentioned our product survey,
which spoke to how robust our
portfolio is. Kevin Boyle, our Chief
Technology Oﬃcer, and his team
will drive greater customer insights
and a better understanding of
needs for our R&D process so that
the products we are developing
even better meet key user needs in
the future, whether that’s digitalization or speciﬁc to endodontics,
aligner treatment, or software. We

want our decisions to be aligned
with global customer data, not only
customer data from the US or from
Germany. Our surveys are global in
nature. We’re receiving input from
around the world, and I think that’s
really important moving forward.
DS Core is going to help us revolutionise the practice of dentistry
as we think about the future of the
industry and how dental care is delivered.

What are your goals and priorities for Dentsply Sirona in the
second half of the year? How does
the company plan to stay at the
forefront of innovation and continue driving positive impacts in
the dental industry?

I think 2023 was a year of building stability in our organisation,
and now we want to move ahead at
pace to deliver on the promises
that we make to dental practitioners. We will continue our digital
dentistry path, including technology and software. We will for sure
continue to accelerate our clinical
training oﬀerings. As I mentioned,
we will be holding a DS World Asia
Paciﬁc this year. We will continue to
expand our presence with respect
to training and expand our footprint for DS Core because we think
it can help every dental practitioner
to make their practices more eﬃcient and more eﬀective. I already
mentioned our commitment to
quality. Internally, we’re doing a lot
of work around our operations to
make ourselves more predictable
and eﬀective in delivering our
products. We are committed to
making our company a better partner and a better company to work
for.

How has the company fostered employee engagement and
maintained a positive company
culture during these organisational changes?

I think that over the past 18
months, we have been very clear in
our strategy and mission. Our leadership team is working hard to articulate our vision, to be transparent with our team members and to
live the shared values of the company. We have created an award
program for our teams and employees whose performance was
exceptional, as well as for employees who have demonstrated a special commitment to the values of
our company, also in the work they
do for the communities in which
they live. We are really excited
about that because we are asking
our employees to go above and beyond to help us re-establish our
company as a great one to do business with and a great place to work.
It’s important that we recognise our employees when they do
great work, whether as an individual or as a team. Diversity, equity,
and inclusion are also extremely
important, and we have monthly
metrics that we assess ourselves
against to guide the trajectory of
our work culture.

INTERVIEW

Dental Tribune Middle East & Africa Edition | 04/2024

From mentorship to mastery:
Prof. Damiano Pasqualini on
advancing endodontics
By Dental Tribune MEA

real world of everyday clinical activity like most of my colleagues.
However, the teaching activity,
both in the under-graduate and
post-graduate programs, is for me
a human and professional satisfaction and a continuous stimulus to
improve that I would not give up
for anything in the world.

As anticipation builds for the
upcoming CAD/CAM & Digital
Dentistry & Facial Aesthetic Conference 2024 in Dubai on 15-16 November, let's take a moment to
shine a spotlight on one of the esteemed speakers. Prof. Damiano
Pasqualini, a leading expert in endodontics and an Associate Professor at the University of Turin, will
share his extensive knowledge in
modern surgical MicroEndodontics. Prof. Pasqualini's innovative
approaches have signiﬁcantly advanced the ﬁeld, and his lecture
promises to be a highlight of the
event.

Your upcoming lecture at the
CAD/CAM & Digital Dentistry &
Oral Facial Aesthetic Conference
2024 will delve into modern surgical MicroEndodontics. How do
you see conferences like this one
contributing to the advancement
of dental techniques?

Prof. Pasqualini, as a leading
expert in endodontics, many clinicians admire your innovative
techniques and insights. What
experiences have most shaped
your approach and success in this
ﬁeld?

I think every successful path
starts with a mentor who inspires
you, guides you and passes on their
passion and skills to you. For me he
was Prof. Berutti, a dear friend and
skilled endodontist, a pioneer in
Italy and in the world of minimally
invasive and micro-surgical endodontics. Subsequently, my constant passion for updating and my
enthusiasm in embracing new
technologies have led me to this
point. New biomaterials and the
digital world have also oﬀered microsurgical endodontics unexpected opportunities until a few
years ago: guided, static and dynamic techniques, virtual and augmented reality to facilitate the
learning curve of young operators,
artiﬁcial intelligence as a diagnostic
aid and decision making are just
some exciting examples of the evolution in this ﬁeld.

What inspired you to focus on
the ﬁeld of surgical Micro
Endodontics, and how have you
seen it evolve over the years?

My career in clinical and university began 25 years ago in the Oral
Surgery division, but since the be-

Professor at the University of Turin. (Image: Prof Damiano Pasqualini)

ginning I have always been fascinated by the elegance of the search
for precision and detail of Endodontics. It was a natural evolution
to move and grow in the Endodontics Division and combine surgical
and endodontic skills through the
binoculars of an operating microscope. Enthusiasm for microsurgical endodontics has grown with intervention, appreciating its low invasiveness, improved quality of life
and high long-term success rates.
For many years it seemed that the
specialty was always the same, that
it did not oﬀer interesting novelties
and that it could not counter the
overwhelming power of implant
marketing, in short, that it was destined to disappear. In fact, in recent
years there has been an exciting return of interest all over the world,
with an exponential spread of
courses, conferences, workshops
and hands-on. I think this is partly

due to recent guided and imaging
technologies, but above all because the costs of managing medium-term implant failures have
pushed clinicians, insurance companies, and scientiﬁc societies to
enormously re-evaluate the importance of preserving an individual's
natural
dentition,
including
through advanced techniques such
as modern surgical endodontics.

What motivates you to share
your knowledge and insights in
dentistry?

I was born as a private practicioner and later I embraced the
university world. Currently, twothirds of my day is spent in university with the triple mission of research, teaching and clinic of complex endodontic cases and patients
with special needs. I purposely
maintain a private clinical practice
to preserve the connection to the

It is an honor to be invited as a
speaker at one of the most popular
events in the world. The program
and the network created by CAPP
go well beyond the days of this important event full of lectures, workshops, in-person and virtual meetings, important social media activities, they positively inﬂuence the
progress of dental specialties and
have an important impact on the
entire community

Could you discuss the innovative microsurgical instruments
featured in your lecture and how
they enhance the performance
and outcomes for both clinicians
and patients?

In my lecture and hands on
workshop the microsurgical endodontic EasyEndo Black kit will be
presented and discussed. It is an
original set of instruments inspired
to simplicity and clinical comfort,
designed by Elio Berutti and myself
in collaboration with HuFriedyGroup. Each instrument combines
simple shapes that any clinician
feels conﬁdent in and precise indications for use. One instrument for
every single step of the complete
procedure to achieve a predictable
successful outcome with no stress.
All instruments are made with
XTS technology, a dark Aluminium
Titanium Nitride coating that does
not shine under the light of the
magniﬁcation device, dazzling the
operator like traditional instruments. It also oﬀers a very nice con-

trast with surrounding soft and
hard tissue and materials during
surgery. These instruments allow
the operator to perform the surgery with simplicity and without
stress, increasing the conﬁdence
and results of the clinician and the
satisfaction of the patient.

How do you envision the role
of advanced technology evolving
in the near future, and what impact do you anticipate these advancements will have on patient
care?

Microsurgical endodontics is
for sure one of the specialties that
in recent years has beneﬁted from
the most advanced technology,
such as 3D imaging, digital planning and guided surgery of complex cases, but the real strength of
the specialty is the solidity of the
scientiﬁc data, of the biological and
surgical principles on which it is
based. Preclinical and clinical training must certainly be strengthened
to allow more and more operators
to successfully embrace these natural tooth preservation techniques.

What advice would you give to
clinicians who are new to MicroEndodontics and looking to incorporate these techniques into
their practice?

Microsurgical endodontics is
by no means reserved for a few talented clinicians. With basic surgical
training, appropriate speciﬁc training and the correct equipment, everyone can perform a successful
and satisfying surgery for the clinician and patients. If you improvise,
the result will be bad and the stress
will be maximum, so you will abandon the procedure and label it as
too complex. Like any surgical discipline, training is crucial, as well as
the equipment must be adequate
and eﬃcient, but it is also necessary to have the patience to follow
a physiological learning curve by
selecting simple clinical cases initially and then over time of increasing diﬃculty.

"Every successful path starts with a mentor who inspires you,
guides you and passes on their passion and skills to you."

Dental Tribune Middle East & Africa Edition | 04/2024

Doubled-edged sword:
AI must foster, not worsen,
sustainability in dental care
By Jeremy Booth, Dental
Tribune International
Given that dentistry is already
struggling to increase equity of care
and reduce its adverse impact on
the environment, the ethical duality
of artiﬁcial intelligence (AI) regarding sustainability poses pertinent
questions for the industry. A 2022
review of the relationship between
AI and oral health generated interest when it called on the oral health
community to actively employ the
technology to foster more equitable
and sustainable oral care. Dental
Tribune International (DTI) spoke
with one of the study authors, Dr
Maxime Ducret, about putting the
ﬁndings into practice.
AI holds promise for advancing
oral health services, yet its alignment with United Nations (UN) and
World Health Organization (WHO)
sustainability standards is not
clearly established. The review emphasised that oral healthcare is em-

bedded in the UN 2030 Sustainable
Development Goals (SDGs)—speciﬁcally, in SDG 3, which emphasises
the promotion and support of
well-being at all ages—and that
WHO advocates for eco-friendly,
minimally invasive dental care, highlighting the role of oral health in
planetary health. While not legally
binding, the SDGs and the WHO’s
strategy for oral health aim to foster
collaborative and measurable action among all stakeholders.
The researchers found that AI
supported certain eﬀorts aimed at
achieving SDGs in oral health, for
example, by reducing transportation, optimising the delivery of oral
care and increasing equity of access
to dental services. However, they
noted that AI could also be detrimental to achieving some of the
SDGs, as its deployment, implementation and maintenance requires resources that may aggravate inequalities. “Also, AI may be biased,
reinforcing inequalities and discrim-

ination and may violate principles of
security, privacy and conﬁdentiality
of personal information,” the authors wrote. They concluded that it
was necessary for the oral health
community to systematically apply
evidence-based assessments to the
positive and adverse eﬀects of AI
tools on sustainable oral health, and
to actively use AI to foster greater
equity and sustainability in the delivery of oral healthcare.
A call to action for sustainability in AI models for oral health
Dr Ducret, who teaches at
Claude Bernard Lyon 1 University,
told DTI that it was crucial to avoid
the risk of selection bias when gathering data for training AI models. “A
random sampling technique and
adjustment of the data set to reﬂect
evolving societal dynamics should
be considered in the future,” Dr Ducret said, adding that transparency
in data collection processes for the
training of AI-powered medical de-

Researcher Dr Maxime Ducret

vices was of great importance, as it permits external scrutiny
Avoiding selection bias requires an expansion
of data collection in developing countries; however, Dr Ducret said that it was diﬃcult to identify
one or two priority measures in this area. He commented: “The aspect that seems most important to
us is creating a framework of trust and sustainability around the sharing of data in all countries and
to securely keep this data as a valuable resource
and recognise a debt towards those who shared
it.”
The review was a call to action, and Dr Ducret
said that the oral health research community is
currently highly active concerning AI-related topics. He explained that several of the study authors
are members of an international WHO research
group that is set to play a major role in the development of sustainable AI tools for dental care. He
explained that this work was ongoing and that
some of its focal points included collaborative databases, innovative tools, comparative studies, improvement of the student curriculum and practitioner training.
The review noted that it remains unclear
whether AI can truly advance the 2030 SDGs in the
ﬁeld of oral health, and Dr Ducret said that it was
important to create awareness regarding these
uncertainties. “Our review helped illustrate the
true duality that AI represents for our society. Currently, many of us have the feeling that we are in a
strategic period from a technological point of
view, but few are informed about and aware of the
paradoxes and issues that are associated with this.
Even though our article raised all these uncertainties, we remain deeply excited for the coming
years,” Dr Ducret said.
Editorial note: The study, titled “Artiﬁcial intelligence for sustainable oral healthcare”, was published
in the December 2022 issue of the Journal of Dentistry.

Using AI to address oral healthcare
inequities requires wide-ranging
collaboration
By Dental Tribune International
Oral disease disproportionately
aﬀects low-income and minority
populations. The use of artiﬁcial intelligence (AI) is increasing in oral
healthcare and shows great promise in revolutionising dentistry.
However, there is little research on
its potential application to addressing equity in oral healthcare
and research. A new review article
by US researchers explores the inequities and biases in oral healthcare and highlights the potential of
AI in addressing these challenges,
speciﬁcally by augmenting oral
health practitioners’ capabilities to
achieve personalised care that is
unbiased and transparent.
Inequities in oral healthcare
arise from a complex interplay of
factors, including aﬀordability, accessibility, availability and discrimination. Additionally, oral health
services are often treated as separate to general healthcare and in
many countries relegated to the
private sector, further limiting accessibility and aﬀordability.
AI presents signiﬁcant potential
to address inequities in oral healthcare, but must be applied responsibly, and this hinges on anticipating
and managing risks, according to
the researchers. The Artiﬁcial Intelligence Risk Management Framework developed by the US National

Institute of Standards and Technology outlines principles for developing transparent and trustworthy
AI systems, including mitigating
harmful biases that can exacerbate
inequities if not addressed during
training of AI models. Another such
framework is the National Academy of Medicine’s Artiﬁcial Intelligence Code of Conduct, which further supports the ethical use of AI
in healthcare to ensure that AI
technologies are applied safely and
fairly to improve patient outcomes.
As AI models become more
complex, their black box nature
poses challenges in understanding
how they make predictions, which
is crucial for trust in healthcare applications. To address this, the researchers recommended incorporating explainable AI (XAI), which
seeks to make these models more
transparent, providing explanations on why and how decisions are
made. AI is key in helping users to
understand both the impact the
AI’s creators intended for the
model and possibilities for biases
within the model. An example is a
class activation map, which shows
the regions of an image most signiﬁcant to the predictions made by
a type of deep learning algorithm
called a convolutional neural network. By incorporating explainability into AI, oral healthcare can
move towards more personalised,

equitable care, reinforcing trust
among providers and patients.
Recent government initiatives,
such as the US Artiﬁcial Intelligence
Safety Institute Consortium and
the National Institutes of Health’s
Bridge to Artiﬁcial Intelligence programme, have been launched to
support responsible AI use by promoting ethically sourced and accessible data set creation. However,
a major challenge to responsible AI

use in oral healthcare is the lack of
universally adopted regulatory and
ethical frameworks. The responsible implementation of AI requires
collaborative eﬀorts across societal, infrastructural and regulatory
domains. By integrating AI responsibly, stakeholders can break down
barriers and promote comprehensive patient care globally, potentially reducing health disparities

and improving equity in oral
healthcare.
The study considered bias in its
full scope, referring to any systematic preference, prejudice or unfair
treatment based on race, ethnicity,
socio-economic status, sex and
sexual orientation, among others.
Bias could include data that does
not fairly represent or serve various
ethnicities, language backgrounds,
socio-economic situations or other
demographics that are already underserved. The researchers pointed
out that the majority of applications in oral healthcare that utilise
AI rely on data from merely seven
countries, exacerbating the potential for bias. The AI Risk Management Framework extends consideration of bias to systemic, computational, statistical and human cognitive biases.
Addressing oral healthcare inequities requires more than making dental care available to underserved communities. It involves addressing the utilisation of, provision of and access to services, and
that access is based on ﬁnancial affordability, physical accessibility
and acceptability.
The review, titled “Responsible
artiﬁcial intelligence for addressing
equity in oral healthcare”, was published online on 18 July 2024 in
Frontiers in Oral Health.

Divine dental: Meeting the oral
healthcare needs of Malaysian Hajj
pilgrims
By Dental Tribune International
Every year, over 30,000 Malaysian Muslims travel to Mecca to perform the Hajj, a pilgrimage that constitutes a central pillar of the Islamic
faith and a religious imperative for
those who are physically and ﬁnancially capable. Their pilgrimages are
facilitated primarily through the
Tabung Haji institution, a Malaysian
government agency that arranges
the ﬁnancial, logistical and health-

care aspects of the journey, including dental care.
This year, the ﬁve-day ritual
cycle of the Hajj occurred between
14 and 19 June, when the daily highs
ranged between 46 and 49 ℃, utterly scorching heat that ultimately
claimed the lives of over 1,300 pilgrims. In such oppressive conditions, the physical well-being of pilgrims is of signiﬁcant concern—and
this extends to dental care.

To this end, the Tabung Haji established a medical centre, including a dedicated dental unit, to ensure the well-being of citizens undertaking the pilgrimage. In a news
article from Bernama, the Malaysian
national news agency, Dr Umairah
Razali, the dentist leading the clinic,
stated that most pilgrims seek treatment for dislodged dental ﬁllings
from eating hard foods such as nuts
and fruits and for ulcers due to in-

suﬃcient water intake, and many require scaling.
The main goal of the dental unit
is to provide pilgrims with a dental
experience as close in quality and
comfort to what they are accustomed to at home in Malaysia. While
some equipment and materials are
easily transported from Malaysia,
others are not. Dr Razali explained:
“It’s diﬃcult to bring dental materials from Malaysia. Some materials,
such as ﬁllings and anaesthesia for

extractions, must be purchased
here. The issue arises when these
materials, despite being the same
brand, aren’t suitable for Malaysians, and the costs are high.”
The dental unit thus provides an
invaluable service to Malaysian pilgrims within a highly challenging
environment and stands to meaningfully contribute to their oral
health for years to come.

Mixed trends stir dentistry majors
By Jeremy Booth, Dental
Tribune International
The ﬁrst quarter of 2024 has
yielded mixed results for dental
companies. Leading dental laser
provider BIOLASE experienced a
22% drop in its US laser revenue,
and global distributor Henry Schein
reported a decrease in sales of
dental consumables in North
America. Meanwhile, Dentsply
Sirona increased its business in
China by 53%, and Align Technology announced a record shipment
in the coveted teens clear aligner
category. The following report
looks at how the largest manufacturers fared during the period amid
restraint from clinicians, patients
and dental support organisations
(DSOs).
Dentsply Sirona takes a cautious stance
First-quarter net sales of
US$953.0 million (€882.8 million*)
at Dentsply Sirona represented a
year-on-year decline of 2.6 and
1.9% negative organic growth—for
which currency ﬂuctuations and
other non-sales-related factors are
excluded. Sales increased by 1.5%
in the US and declined by 5.2 and
4.4% in Europe and the company’s
remaining markets, respectively.
Looking at its segmented results, Dentsply Sirona recorded
global year-on-year sales declines
of 6.9% for its connected technology solutions segment and of 5.9%
for its essential dental solutions
segment. Sales increases of 4.4 and
5.4% were posted for its orthodontic and implant solutions segment
and its Wellspect Healthcare business, respectively.
Simon Campion, CEO of
Dentsply Sirona, told analysts that
organic sales were mostly ﬂat
during the period, except in Germany, where survey results showed
that procedure utilisation and dentist outlook had improved. Sharing
more of the company’s market intelligence, Campion said that dentists in Australia continued to exhibit some negative sentiment
about market conditions, that patient volumes had declined in Japan
and were stable in China and that
Canadian patients seemed to have
delayed treatment during the period, owing to the phased roll-out
of the country’s new dental plan.
“We are taking a cautious
stance here with the macro uncertainties that continue to impact
parts of our business, most notably
imaging,” Campion said.
Glenn Coleman, Dentsply Sirona’s chief ﬁnancial oﬃcer (CFO),
alerted investors to the company’s
ﬁrst-quarter highlights—53% sales
growth in China, a 14% increase in
global clear aligner sales and 9%
growth in CAD/CAM— all of which
were oﬀset by declines in sales of
imaging equipment. Global sales of
SureSmile clear aligners increased
by 9% and the company’s di-

rect-to-consumer aligner, Byte,
grew by 18%, bucking a negative
trend in the demand for at-home
aligner systems.
Align Technology ships more
teen cases than ever before
The maker of Invisalign had the
ﬁrst quarter it needed after a run of
disappointing results in 2023. Sales
at the company reached US$997.4
million, a 5.8% year-on-year increase. Clear aligner revenues, at
US$817.3 million, were up by 3.5%,
and those from imaging systems
and CAD/CAM services increased
by 17.5% to reach US$180.2 million.
First-quarter shipments of clear
aligners increased by 2.4% year on
year to reach 605,060. At 199,200,
Align’s teen shipments were up by
5.8% and greater than in any quarter previously. CEO Joseph Hogan
told investors that Align had
achieved a number of milestones
during the period, such as the acquisition of Cubicure, a leader in direct 3D-printing solutions, which
Align hopes will revolutionise its
production process. The company
also launched the Invisalign palatal
expander system in the US and
Canada, and Hogan said that it was
one of the most signiﬁcant innovations in the company’s 27-year history.
Straumann Group posts 15%
organic growth
Yang Xu, CFO of Straumann
Group, told analysts in the company’s earnings call that the multinational had had a “solid quarter”.
Sales of CHF643.8 million (€660.8
million*) represented year-on-year

growth of 8.1%, or 15.1% on an organic basis.
Straumann had minor year-onyear revenue declines in the Europe, Middle East and Africa (EMEA)
and the North America regions,
where sales decreased by 0.9 and
2.3%, respectively. However, all regions returned organic sales increases: 5.2% in EMEA, 3.7% in
North America and 11.5% in Latin
America.
Straumann
banked
CHF130.8 million from sales in the
Asia Paciﬁc region, representing a
63.7% increase in revenue and an
82.0% increase in organic sales.
This strong year-on-year growth is
partly due to the company’s comparatively weak performance in the
region in the ﬁrst quarter of 2023.
Guillaume Daniellot, CEO at
Straumann, remarked that the
company’s performance in China
had been a highlight of the quarter.
He said that Straumann’s business
in the burgeoning dental market
continues to grow, having gained
momentum last year, when the
company doubled its implant shipments compared with 2022. EMEA
remains Straumann’s largest market, and regional sales to clinicians
of the ClearCorrect aligner brand
increased by double digits during
the period.
ClearCorrect performed well in
the North America and the Asia Paciﬁc regions, contributing to strong
orthodontic sales in established
markets such as the US, Australia
and Japan and in emerging markets such as Vietnam and India.
“On the challenging side, we
still see headwinds in the doctor-led direct-to-consumer busi-

ness, namely DrSmile,” Daniellot
said, citing persisting macroeconomic challenges among consumers. He said that Straumann had
shifted from paid marketing to organic demand generation for
DrSmile and had achieved 3.7%
growth in North America, despite a
“softening market”.
Envista says patients will prioritise dental care
In Amir Aghdaei’s last earnings
call as Envista CEO, and his successor’s
ﬁrst, the outgoing chief said that the
quarter had proved challenging and
resulted in modest growth. Envista
earned US$623.6 million in sales
during the period, some US$3 million
less than a year earlier. Core sales (for
which the impact of foreign currencies and acquisitions are excluded)
were ﬂat, at 0.4% growth, and a yearon-year gain in operating expenses
led to a US$24 million drop in operating proﬁt.
Addressing Envista’s double-digit decline in North America
in the prior quarter, Aghdaei said
that aggressive and proven steps
had been taken to return to growth
in the region, including investing in
implant and clear aligner sales and
training over 3,000 dental professionals. First-quarter growth in
North America eluded the company, despite strong orthodontic
sales led by Spark aligners and a
stabilisation of demand in diagnostics.
Envista CFO Stephen Keller said
that ﬁrst-quarter sales in the company’s developed markets had declined by 1.7% and that the sales
declines seen in North America and

Western Europe were similar in
size. “Our emerging markets grew
10.2% in the quarter with very
strong growth in China, oﬀset by
continued volatility in Russia as
well as weaker demand in Latin
America,” Keller added.
Succeeded by Paul Keel on 1
May, Aghdaei led Envista and its
dental
companies—previously
under the Danaher banner—for
nearly ten years. The widely respected CEO said that the company
continues to see mixed trends
across dental markets, despite a
largely stable macroeconomic environment. He explained: “Overall,
patient traﬃc remains resilient;
however, demand appears to be
[tending] more towards basic hygiene and restorative treatments.
Demand for higher-end specialty
procedures, including adult orthodontic cases and full-arch implant
restorations, remains more muted
[and] private practice clinicians and
DSOs remain cautious about nearterm investments in both equipment and clinic level inventories.”
Aghdaei added: “Long-term, we
are conﬁdent that patients will prioritise dental care and that clinicians will proactively invest in areas
that help them digitise their practice, making them more productive
and ensuring that they can provide
high-quality personalised care.”

Lipid metabolism and maternal weight
inﬂuence orofacial cleft risk in infants
By Anisha Hall Hoppe, Dental
Tribune International
Orofacial clefts (OFCs) occur at a
slightly higher rate in Asia than elsewhere—1.6 cases per 1,000 live
births compared with one in 700–
1,000 globally—and place a major
burden on families regarding
healthcare and psychosocial aﬀects.
A study conducted in Thailand has
investigated whether metabolic
syndrome is a factor in such congenital defects and determined that
mothers outside of normal weight
ranges are more likely to have a
baby with an OFC. Those with low
levels of high-density lipoprotein
cholesterol (HDL-C) also have increased OFC risk, highlighting the
importance of lipid metabolism in
OFCs.
In north-east Thailand, between
June 2017 and May 2021, the researchers studied 94 infants with
cleft lip with or without cleft palate
and 94 controls frequency-matched
on age and mother’s education
level. Data collection included maternal health questionnaires, an-

thropometric measurements and
blood samples measuring HDL-C.
Metabolic syndrome was deﬁned
using the International Diabetes
Federation criteria, requiring central
obesity plus two additional risk factors.
Mothers with a body mass index
that was considered overweight
were at a 2.44 times higher risk of
having infants with OFCs compared
with mothers of normal weight, and
obese mothers were at 3.30 times
higher risk. Mothers with low maternal HDL-C levels were also 2.95 times
more likely to have children who developed OFCs. Although not a statistically signiﬁcant ﬁnding, mothers exhibiting four or ﬁve features of metabolic syndrome showed an increased
likelihood of having children with
OFCs. Surprisingly, mothers who were
underweight were 2.93 times more
likely to have a child with an OFC.
The results remained consistent
when excluding infants with a family
history of OFCs and among mothers
not currently breastfeeding or those
more than six months postpartum.
The study ﬁndings corroborate

those reported in other countries
and suggest the importance of promoting strategies to maintain optimal body weight and enhance
HDL-C levels among reproduc-

tive-age and pregnant women to
potentially reduce the risk of OFCs
in their children.
The study, titled “Maternal metabolic status and orofacial cleft risk:

A case-control study in Thailand”,

2024 in the International Dental
Journal, ahead of inclusion in an

New study shows bacteria
love some restorative materials
more than others
By Dental Tribune International
Although various synthetic materials have achieved near-perfect
results in dental restorations, they
cannot completely replicate natural
tooth structure, often resulting in
clinical failure due to secondary caries and periodontal disease. Two
major contributing issues are the
formation of bioﬁlm and bacterial
adhesion to restorative materials.
Using single-strain bacterial adhesion models, researchers in Japan
have investigated the inﬂuence of
dental material type and surface
properties on bacterial adhesion.
The ﬁndings suggest that the chemical composition of the material
plays a crucial role in bacterial adhesion, potentially more than surface
roughness or surface energy.
The study investigated three
grades of yttria-stabilised zirconia
and a CAD/CAM composite resin.
Bovine dentine served as the control. The surface roughness of all

materials was maintained at a highly
polished level. The materials were
tested against the strains of ﬁve
bacterial species: Porphyromonas
gingivalis (implicated in periodontal
disease), Streptococcus oralis, Streptococcus sanguinis, Streptococcus
gordonii (all three early-colonising
bacteria) and Streptococcus mutans
(associated with dental caries).
The results showed that there
were no signiﬁcant diﬀerences in
surface roughness among the
highly polished samples. Surface
wettability varied, but no correlation was found between surface energy and bacterial adhesion. The yttria content in the zirconia did not
signiﬁcantly aﬀect bacterial adhesion. However, the composite resin
exhibited higher bacterial adhesion
compared with zirconia, attributed
to its higher carbon, oxygen and silicon contents.
Bacterial adhesion patterns differed among the materials. For
P. gingivalis, the control group

showed the highest adhesion and
the composite resin the lowest. For
S. oralis, S. sanguinis and S. gordonii,
the highest adhesion was observed
on the control and composite resin
surfaces, followed by the zirconia
samples. For S. mutans, the control
group showed signiﬁcantly higher
adhesion compared with the experimental groups. The researchers
noted that “the results clearly show
that the material type strongly affects bacterial adhesion during the
ﬁrst hour of incubation, which is an
important factor for clinical use”.
This study conﬁrms that dental
material type signiﬁcantly inﬂuences bacterial adhesion, even
when surface roughness is controlled. The composite resin, despite
its polished surface, showed higher
bacterial adhesion, similar to the
control with a rougher surface. Considering both mechanical and biological properties when selecting
materials for dental restorations is
key, according to the researchers.

They recommended further research, including co-culturing models and long-term studies, to fully
understand the biocompatibility
and clinical performance of these
materials. “Given the complexity of
the physicochemical properties of
diﬀerent materials, we suggest that
biological indicators related to bacterial adhesion should be explored
for optimal clinical outcomes,”
wrote the researchers. Employing
bioactive agents and superhydro-

phobic surfaces in restorative materials may oﬀer future solutions for
reducing bacterial adhesion and improving clinical outcomes.
Editorial note: The study, titled
“Does dental material type inﬂuence
bacterial adhesion under the same
polishing conditions? Direct observation using a ﬂuorescent staining technique: An in vitro study”, was published online on 1 June 2024 in Dental
Materials Journal, ahead of inclusion in
an issue.
