DR. DOMENICO MASSIRONI
AND THE MODIFIED CHAMFER
During the course, Dr. Massironi demonstrated his vision of minimally invasive
dentistry to maintain tissue integrity as
far as possible for a predictable and harmonious result. Over the four days, the
participants were taught the modified
chamfer technique, which can be used
with every type of material and restorative technique currently available.
This marginal finish design is part of a
greater preparation system using rotating
instruments driven by electronic devices,
such as an induction micromotor, and
pneumatic oscillating instruments, without rotation of the working instrument,
that include sonic inserts and manual
instruments, such as rounded chisels. This
method is almost entirely independent of
individual skill and thus suitable for every
clinician, as it is not operator sensitive. It

involve both clinicians and dental technicians with the aim of achieving a perfect
anatomical, functional and esthetic integration of the prosthetic restoration into
the patient’s mouth. In this regard, the
preparation of the tooth has always represented one of the most important procedures for the patient’s rehabilitation by
fixed prosthesis.
The modified chamfer described by
Dr. Massironi consists of a preparation
design with a more rounded chamfer curve
compared with the traditional chamfer and
longer than the rounded shoulder, in order
to gain a profile that adapts well to

different types of restorative material. This
modification results in a shallow (and thus
less aggressive) preparation that is less
operator sensitive compared with the
more traditional shapes, such as a rounded
shoulder or 90° shoulder.
The choice of marginal finish for fullcrown prosthetic preparation is usually
according to the clinician’s skill. The latter
depends on what the clinician learned
during his or her undergraduate education
or in postgraduate courses presented by
more experienced colleagues, or his or
her personal expertise. For these reasons,
such choice is often motivated by ease

and experience criteria, though sometimes it may depend on the type of restorative material or on the intrinsic characteristics of the tooth. Furthermore,
abutment height, number of teeth to be
splinted, adhesive cementation system
and esthetic needs may affect the choice.
The proposed modified chamfer design is
innovative and universal, because it may
be adapted to every kind of prosthetic
restoration and marginal closure, including the complete marginal border, the
microborder where the metal, opaque
material and ceramic converge, metalfree methods and CAD/CAM technologies, and shoulder structures or full feldspathic ceramic. Its great versatility is also
associated with its easy clinical use,
because its particular shape makes it less
sensitive to clinical ability; thus, it is less
operator dependent compared with other
common horizontal marginal finish
designs.
The main challenge nowadays is finding
the right balance between a minimally
invasive approach and an excellent esthetic result. Esthetics is a direct consequence
of maintaining the tooth’s health and
function.

“One has to have some
level of passion. Things

opened for me and I just
sort of ended up where
I am, but it was always
something that I was
fascinated with.”

INTERVIEW
with — Prof. Edward A. McLaren
Nathalie Schüller for Dental Tribune International: Prof. McLaren, you began your
career as a general practitioner. What
sparked your interest in esthetic dentistry
and dental design? What were your influences? Perhaps a mentor?
A: I was always interested in dentistry as a
child. After I became a general dentist,
I gravitated toward treating more complex
cases very early on and I wished to specialize. In practicing, I really enjoyed most the
artistic aspect of what I was doing and
I became involved in esthetic dentistry
naturally, because of the interest in that.
I had the opportunity to see the work
of master ceramist Willi Geller when I was
in dental school; it was something I had
never seen or experienced in dental
school—it had not even been talked
about—and it really motivated me. If I had
two mentors, one would be a dentist,
Dr. John Sorensen, and the other a technician, Klaus Müterthies; they took me
under their wings and motivated me to do
what I do.
But like anything, one has to have some
level of passion. I have always enjoyed
working with my hands and the aspect of
esthetic dentistry relating to art is

appealing to me. Things evolved and pathways opened for me and I just sort of ended up where I am, but it was always something that I was fascinated with.

Q: You do your own ceramics. Would you say
that you are a perfectionist or an artist in
your own way?
A: I would like to define myself as an artist.
The more I do that, the more artistic I feel,
the more passion I feel toward esthetic
dentistry and designing smiles. First of all,
one needs to define oneself in a certain
way. A musician is someone who just plays
music, even if she is not very good at it. It
really does help one’s mindset, because we
tend to be self-negative. If one truly wants
to be something, one has to start seeing
oneself doing it.
Q: Is creating your own ceramics also because the results you envision are difficult to
relate to others or it is
difficult to let someone
else do it for you?
A: I would not recommend dentists learn to
do ceramics themselves. Like anything
else, it takes five to ten
years to become pretty
good at it. I do it just
because—and this applies generally to the
things that I do—it is the
thing that gets me into
the most peaceful
state. When I am with
patients, sometimes I am stressed, the
phone is ringing, so even though I love
doing that, when I sit down and create ceramics, it just puts me in such a state of
bliss. That is what I enjoy most about it.
Many dentists take my course thinking
they want to save money by not paying a
ceramist; well, that is the worse reason to
do it. It has to be something that one is
passionate about. What makes a good
esthetic dentist? Someone who likes art,
whether doing the teeth himself or herself,
as composites, or having to evaluate what
is good and bad dental art. That requires a
certain personality. Some people have it,
some do not and one just needs to be honest with oneself. It is about finding something that does not feel like work when one
is doing it; one just enjoys it.

esthetic dentistry definitely
needs to become a

SMILE REHABILITATION
— A direct therapeutic approach assisted
by digital diagnosis and mock-up
Dr. Didier Dietschi, Switzerland

A successful rehabilitation in the esthetic
zone depends on criteria that are wellknown today, and the use of a direct technique is not an exception to the rule. On
the contrary, a general approach without
preparation—or at least an ultraconservative approach (reshaping the enamel or
preparing a cavosurface bevel if necessary)—might even add a hint of additional
complexity. As a reminder, the most
impor tant parameters that must be considered are the following:
– the integration of the shape (teeth in
relation to the smile and the face) and
implicitly its impact on function;
– the shade in the broad sense (in relation
to the tissue and the adjacent teeth),
encompassing mainly the color, the
luminosity/translucency, the chroma,
the opalescence and the fluorescence;
– the surface micromorphology and the
luster of the restorative material; and
– the biological, functional and esthetic
continuity of the restorations.
When considering a rehabilitation in
young patients, who often need professional dental care from their teenage
years, the direct technique is most frequently required because of the anatomical and functional immaturity of the
dental arches. The procedure should include the use of a material or technique
that will make possible the necessary adjustments and modifications resulting
from the ongoing bio-functional dental
development of the patient. Among the
criteria to be considered when selecting
the composite system, the material
strength and its ease of use should be prioritized in order to achieve an optimal

esthetic result. The layering technique
must therefore be effective and simple;
in other words, it is futile to perform complicated multilayering methods in the
daily practice and there is a definite advantage to using products that are based
on the Natural Layering Concept (e.g.,
inspiro, Edelweiss DR; Miris, Coltène/
Whaledent; Essentia, GC; Enamel HRi,
Micerium). This article will highlight the
advantages of this technique that, as its
name suggests, makes use of the anatomical characteristics of the natural tooth
(contour, volume and thickness of the
dentin and enamel). This significantly simplifies the clinician’s work, provided it is
associated with functional and esthetic
planning tools, as described next.
Once the choice of therapeutic approach and restorative system has been
confirmed, it is very important to develop
a comprehensive esthetic and functional
plan in order to improve the communication with the patient and to help the dentist to elaborate his or her restorative and
layering techniques if needed. Nowadays,
simplified approaches are available, compared with the conventional wax-up and
hand-fabricated acrylic mock-ups; indeed,
digital imaging and even programming
tools of numerous CAD/CAM systems
(e.g., CEREC, Dentsply Sirona) offer innovative solutions, also outlined in this
article.1, 2
A successful treatment, especially an
esthetic treatment, relies on the implementation of a standardized therapeutic
approach and clinical protocol, including
ideally any development aiming to make
them more reliable and simpler. The esthetic treatment plan using software tools
(general software, dental software or a
CAD/CAM system) has made a comeback
and its use has become more prevalent,
and is likely to remain so.1, 2 Besides a

legitimate concern of simplification and
cost-effectiveness, the thrust of this approach is to contextualize and allow the
preview of the treatment during planning,
before any procedure has been performed in the mouth. The advantage is
twofold, both in terms of communication
and prior acceptance of the result by the
patient. Of course, sensitive situations
with patients who had expected a result
that is impossible to achieve with the therapeutic means at the clinician’s disposal
should be avoided.
With regard to the choice of restorative
material, while also attempting to meet
the multiple requirements related to the
dental biomechanics, function and the
esthetic aspects, the decision criteria
should be redefined in light of the latest
developments in composites and their
longevity properties. A comprehensive
perspective encompassing the long-term
outcome of the tooth and its restoration
should be explained to the patient in order
to assist him or her in determining the
most appropriate choice. Very often, the
best way is to sacrifice the weakest tissue.
Today, a basic approach involving the use
of direct composite resins in addition to
whitening and microabrasion would therefore be a sensible approach for young
patients in need of esthetic treatment, as
highlighted in this article. In this area, a
concept embracing both the shade and
the layering has gradually established itself as the most effective solution.

MANAGING
THE PERIIMPLANT
MUCOSA:
— A clinically reliable method
for optimizing soft-tissue contours
and the emergence profile
Drs. Andrea Parpaiola, Luca Sbricoli,
Riccardo Guazzo, Eriberto Bressan &
Diego Lops, Italy

Introduction

— Dr. Diego Lops

22 — issue 2017

Distinctive characteristics of the periimplant mucosa differentiate it from periodontal tissue.1 The difference lies in the
absence of cementum. In fact, the collagen bands lie differently at the site of the
implant. The fibers are set in the periosteum at bone crest level and spread parallel to the implant surface, or they align
in broad bands that, in more distant areas,
expand almost perpendicular to the implant surface. These horizontal fibers
seem to bend vertically and appear to
run parallel to the implant’s surface in
the areas nearest to the implant.1, 2 The
connective tissue at the implant interface contains a larger amount of collagen, but fewer fibroblasts and vascular
structures, than the tissue adjacent to
natural tooth structure. 3
The successful restoration of lost
teeth in the anterior region of the mouth
has to meet both esthetic and functional parameters. In addition to the correct
placement of the implant fixture, it is
essential to achieve a soft-tissue morphology that is as physiologically realistic
as possible. An impression obtained with
standard copings enables the 3-D position of the implant fixture to be reproduced on a laboratory model. However,
the reproducibility of the periimplant
soft tissue is often difficult to control,
and this can compromise esthetics in the
final implant restoration. Most healing
abutments have a cylindrical shape,
which is not suitable to reproduce

correctly the emerging profile of the
natural teeth. The dental technician can
model an implant-supported prosthesis
with a cylindrical profile or with a more
appropriate esthetic profile based only
on an assumption of the shape suited to
the clinical situation. In fact, final tissue
heights of the papillae and buccal gingival margins, relative to their pre-implant
position, are ultimately dictated by the
post-healing levels and position of the
interproximal and facial bone.
Because of its characteristics, the
periimplant mucosa can be modified by
a sculpting process based on the principle that soft tissue becomes modifiable
after controlled, constant compression.
Especially in patients with a thick gingival
biotype, this tissue can be manipulated
to reproduce the normal scalloped, parabolic gingival contours. Different approaches have been suggested by the
current literature on soft-tissue profiling.4–6 All of these focus on establishing
a contour of the provisional prosthesis
that is as accurate and stable as possible
so that it can be faithfully reproduced in
the definitive prosthesis.
The present paper describes a method
that has been consolidated over several
years of clinical practice for the periimplant soft-tissue profiling in the anterior
areas. By following the procedure described in the next section, it is possible
to recreate, in cooperation with the dental
technician, the correct emergence profile for both single and multiunit prostheses.

Clinical procedures
This prosthetic procedure is to be used
after the healing of the periimplant
soft-tissue by means of standard healing
abutments so that a round shape of the
periimplant mucosa can be achieved. An
impression can then be obtained by
screwing the standard pickup coping to
the fixture. A polyether (Impregum, 3M
ESPE) material can be used for the impression in order to provide a provisional
screw-retained prosthesis (Fig. 1).

This provisional restoration is provided to
create and condition the periimplant
soft-tissue contours, thus reproducing
the physiological scalloped, parabolic appearance and the tropism of the adjacent
gingiva. The resin provisional prosthesis is
kept in the oral cavity for a period of three
to six months to ensure a stable outcome
of the periimplant soft-tissue conditioning process. During this period, the patient should be followed monthly and the
clinician should adapt the provisional
prosthesis by adding or removing small

amounts of resin as necessary in order to
obtain the required shape for the gingival
contours and the appropriate emergence
profile. This conditioning process has to
be carried out gradually to avoid excessive
compression, which would cause unacceptable discomfort for the patient.
Once the required gingival morphology
has been achieved (Fig. 2), the procedures
for providing the definitive restoration can
be carried out. The implant analogue is
embedded into laboratory stone (or plaster) in a mixing cup and allowed to set. This

procedure can be done prior to the clinical
appointment to save chair time. At the
time of the clinical appointment, the provisional restoration is removed from the
oral cavity and screwed to the implant analogue. A polyether material is then placed
into the mixing cup (Fig. 3a) so that the
provisional restoration is put into the impression material at the level of the prosthetic emergence profile (Fig. 3b).
This generates a static reproduction of
the soft tissue and in particular of the subgingival portion of the provisional prosthesis. After polymerization of the polyether,
the provisional prosthesis is unscrewed
(Fig. 3c) from the implant analogue and
replaced, in the same supporting cup, with
the stock hexed transfer coping for the
final impression. A space is thus created
between the polyether material and the

24 — issue 2017

impression transfer coping (Fig. 3d); this
space reproduces the morphology of the
periimplant soft tissue. Such procedures
are more suitable for screw-retained provisional restorations because of the simple
removal of the provisional prosthesis from
the implant analogue in the mixing cup.
Next, cold self-curing resin (TEMP RED,
Micerium) is poured into this gap and left
to set (Fig. 4a). A custom transfer coping
for this single implant site is thus obtained
(Fig. 4b). This modified transfer coping is
then removed and screwed on to the implant in the oral cavity (Fig. 4c). The resulting device is an exact periimplant
soft-tissue replica and fits perfectly to the
shape of the marginal mucosa after the
soft-tissue conditioning. No compressive
effect on the mucosa or impression material gaps are generated by the rigid resin
around the transfer coping as sometimes
occurs with the silicone or polyether materials commonly used for precision impressions. A conventional impression can
then be taken. By means of a custom impression device, a definitive impression is
obtained, so the customized transfer coping with the resin remains embedded in the

Digital Workflow and
Esthetics

Article

impression material on the device (Fig. 4d).
Finally, a CAD/CAM abutment can be provided to reproduce the emergence profile
obtained with the provisional prosthesis.
The definitive restoration will be put into
position and naturally follow the scalloped
periimplant marginal mucosa (Fig. 5a). A
stable outcome can be achieved because
of the absence of any soft-tissue compression (Fig. 5b). This method may be used
for the restoration of both single and multiple gaps (Fig. 6).

Discussion
An emergence profile that mimics the
natural tooth should be obtained for successful esthetic implant restoration.
Moreover, it allows proper hygiene, which
is fundamental for implant maintenance.5
The best way to achieve the correct emergence profile is to sculpt the periimplant
mucosa by means of a provisional prosthesis. Only the thick gingival biotype can
be manipulated, as postulated by
Berglundh et al. 3 and Simeone et al.4 In
fact, the thin gingival biotype is not

suitable for sculpting because its compression does not lead to a controlled
scalloping, but to a high risk of soft-tissue
collapse and gingival recession.7
Standard healing abutments and transfer copings do not simulate the crosssection of natural teeth8 because they are
round. Many authors agree that the final
prosthetic rehabilitation must match the
intraorally obtained soft-tissue modifications.5, 9–11 Prefabricated provisional crowns
cannot mimic the complexity and the variations of human soft tissue. Therefore,
only a chairside modification of the provisional restoration can accomplish the optimal result. Moreover, the same authors
agree that provisional restoration has to
be screw-retained to prevent the irritating
side effects of provisional cement on the
periimplant soft tissue, especially in situations in which frequent removals of the
provisional restoration are required. In
addition, crucial for achieving a successful
esthetic outcome is the transfer of the
impression information to the dental laboratory.12 The operator should choose an
easy and reproducible technique to transfer the emergence profile to the impression and therefore the model cast in order
to allow the dental technician to create a
suitable contour for the best esthetic outcome of the final restoration.
The self-curing resin used for contouring the impression coping is common in
the dental practice; moreover, it is easy to
manipulate and inexpensive. It can be
easily poured into the gap between the
coping and impression material as long as
it is fluid. Because of its low shrinkage, the
modified impression coping accurately
reproduces the soft-tissue contour

Esthetics

obtained with the provisional restoration.
Consequently, the exact shape of the
resin-generated emergence profile will be
transferred to the definitive restoration.
Another important advantage of this
technique is that the patient is not left
without the prosthesis for a long period
during the definitive impression procedures; in fact, the customized transfer
coping can support the periimplant
mucosa. Tissue collapse and volumetric
changes will be avoided and the softtissue sculpting will remain stable. Furthermore, the technique presented is
easily reproducible and does not require
particular operator skills.

Conclusion
In highly demanding areas, where a good
esthetic outcome is as essential as the
function of the implant-supported restoration, soft tissue can be modified to
obtain an optimal emergence profile and
gingival contours with a physiological
appearance as realistic as possible. The
method described allows for faithful reproduction of the conditioned soft tissue
when the final impression is taken; thus,
its reproduction on the definitive restoration is possible. The main advantage of
this approach is the easy and reproducible
use of an inexpensive material that is
easily available to clinicians.

“The course is

any particular
group based on
their experience
or age; we
provide a map

surgery.”

Q: Prof. Labanca, how did you become involved in the Clinical Masters™ Program?
A: I started offering this course in Brescia,
Italy, in 2001, once a year, to Italian-speaking dentists. From 2005, I also offered the
course in Vienna, Austria, still for Italian
dentists, until 2015. Starting in 2016,
I brought it back to Brescia, where I teach
anatomy at a medical school. It has been a
great success; so much so that last year we
had to offer two courses in Italy and had
many new participants who learned about
it from their colleagues. This means that
we have to do very little to promote it.
I wanted to bring this course to an international audience as well and started to
offer the course again in Vienna in 2016,
but in English. I had known about and been

34 — issue 2017

interested in the Clinical Masters™ Program as a mean of making the course international. I feel our course is so important and unique that dentists all over the
world could benefit from it. Becoming part
of the Clinical Masters™ faculty gave me
a great opportunity to do so.
Q: For what reason did you decide to offer
your course in Vienna rather than Italy, since
you were already offering it there?
A: This is an essential course and it can only
be given in an anatomical institute, not in
a dental school or in any private venue.
Mainly, the location in Italy did not allow
us to offer the course to as many participants as we could (12 in Italy, 20 in Vienna).
Also, Vienna is more central and thus more

Interview

accessible from other countries, so it is
better suited as an international location.
Q: Why do you think there is a need for this
course? Do dentists not receive this kind of
training during their studies?
A: There is usually a huge lack of information about anatomy. The participants in this
course may be students or practicing dentists. Perhaps they do not have enough
experience of surgical treatments or they
might have done their surgical training
without sufficient anatomical guidance.
Learning more about anatomy is the right
way to start. In a way, it is like getting a
map of a city. One might need a map of
Vienna because one is new to the city and
needs to find one’s way about or because

one has been living there for years, but did
not know enough of the city. A map will
allow one to understand why it is better to
go this way, move in this or that direction.
The course is not aimed at any particular
group based on their experience or age;
we provide a map of anatomical surgery.
Through this course, participants will gain
more skills and confidence in moving inside
the “city”, guided by the anatomical landmarks of their patients.
Q: What would you say are the most important aspects that make this course unique?
A: There is a major difference between this
and other courses in which cadavers are
dissected. In anatomy, dissection is useful
and important, but not for learning how to
perform surgical procedures.
Our course is an anatomical and surgical
course. We demonstrate the most important surgical procedures, for example a
sinus lift augmentation, guided by the
anatomy. We do not tell the participants
how to perform a sinus lift, since the
course is not about surgical techniques or

the materials and instruments they need,
as well as the latest versions available on
the market. The advantage for companies
is that they can assist the participants who
use their products and share the information about the course.
Lastly, we work with fresh specimens,
not fixed ones. If one uses a fixed specimen
in performing anatomical procedures,
some structures are lost. A fixed specimen
is perfect for dissection where one only
needs to see the anatomical structure that
is the focus, but one needs to see the most
important structures, the nerves and arteries, in performing any surgical procedure. The fresh specimens are frozen and
kept at –80 °C and then thawed so that
they are perfectly preserved and their anatomical structures clearly recognizable.
With our specimens, all the arteries have
been injected with a special rubber (red
resin) to retain the same dimensions and
consistence of those of a living patient.

which procedure should be used. Technique and surgical procedure are mainly a
matter of personal preference or background. Our goal is to give participants, no
matter the technique they use, information to avoid anatomical risks. For example,
in placing an implant, we focus on the relevant anatomical structures to be considered. That is the main issue. Surgical techniques may be different, but anatomy is
the same all over the world.
Furthermore, this is the only current
noncommercial course. Companies provide us with materials of course, but they
are partners and supporters only. My colleagues, professors of anatomy whom I
teach with, and I are totally independent.
We do not receive payments from any of
the companies that provide materials and
instruments, allowing us to maintain our
independence. We seek to share anatomical information, and this is not linked to
products or materials as surgical procedures are. We have an association with 15
companies, the most significant in their
field. The participants have access to all

Interview

Anatomical
Surgery

Q: How is the course organized? How many
people attend the course?
A: We have ten workstations at which the
twenty participants work in pairs. Every
workstation has two tutors, one for anatomical questions and one for dental and
surgical questions. Questions arise in both
disciplines and I can answer the ones related to surgery, but an anatomical specialist answers questions on the anatomy.
Anatomy is a very wide field and our tutors
are full professors specialized in orofacial
anatomy.
Such topics as diagnosis, developing a
treatment plan, biological assessment,
guided surgery and using the materials
available are covered during the teaching
section. In the practical part, we perform
surgical techniques to demonstrate the
areas of risk, prevention and management
of failures, and pain management in
dentistry.

COMBINED SURGICAL
AND NONSURGICAL
— endodontic retreatment for
the management of an unusual
clinical case
Dr. Francesco Maggiore, Italy

Introduction
The ultimate goal of endodontics is to
treat or to prevent endodontic pathology
by properly cleaning, disinfecting and filling the complete root canal system. This
is generally achieved by one of the three
major endodontic therapies:

present article reports on an unusual clinical case treated by nonsurgical endodontic retreatment followed by surgical endodontic retreatment in order to remove
a foreign metallic object from the periapical tissue and to properly treat the
apical third of the root. The object was
afterward identified as a wrongly positioned endosseous implant that was responsible for the symptomatology.

patient rescheduled for surgery at the next
appointment.

tooth was opened and the canal filled with
a pulp canal sealer and warm gutta-percha
released from the Obtura II syringe
(Obtura Spartan Endodontics). After
completion of the root canal filling, the
surgical treatment followed. A paramarginal flap was incised (Fig. 5), and after
elevation of the soft tissue, an endosseous
implant became visible under the mucosa
(Fig. 6). The implant was wrongly positioned in the submucosa rather than in
the bone and was actually responsible for
the painful symptomatology.
In order to eliminate the metallic object,
the bone around the post was gently curetted (Fig. 7) and the implant was

vibrated with ultrasonic tips. The implant
was very tightly wedged in the root, and it
was thus decided to cut the apical part of
the root containing the metallic post.
Once the apical part of the root, together
with the metal post, had been removed
(Fig. 8), inspection of the resected root
surface was performed under the operating microscope under high magnification.
The resected root presented with a metal
ring that corresponded to the cave part of
the implant (Fig. 9). Since the metal ring
contained old gutta-percha that was potentially infected, attempts to loosen the
metal ring with ultrasonic tips were made
(Fig. 10). Using ultrasonic tips, the metal

ring was displaced (Fig. 11). The apical part
of the root was further cleaned with ultrasonic tips and filled with grey mineral trioxide aggregate (MTA; Figs. 12 & 13). The
surgical flap was closed using 7-0 monofilament sutures (Fig. 14). The immediate
postoperative radiograph showed good
adaptation of the MTA in the apical part of
the root (Fig. 15). The sutures were removed 48 hours after the surgery (Fig. 16).
At the following control appointment,
the patient was asymptomatic and the soft
tissue showed good healing. The patient
was recalled one and three years after the
surgery. At the recall appointments, the

tooth was asymptomatic and showed good
stability. The three-year follow-up radiograph showed bone regeneration and reformation of the lamina dura around the
amputated root (Figs. 17 & 18).
The patient was referred to our clinic
for endodontic treatment on a different
tooth ten years after the surgery. A control of tooth #23 was done. It had remained
symptom-free, and the ten-year follow-up
radiograph showed a stable bone condition
and the absence of any apical radiolucency
(Fig. 19). Inspection of the soft tissue
showed barely visible evidence of the incision (Fig. 20).

Discussion
The present case report has demonstrated that sometimes an approach combining both orthograde and surgical treatment is required in order to treat
previously endodontically treated teeth
and to provide a long-term favorable outcome. The decision to proceed surgically
or nonsurgically is sometimes determined
by the intraoperative conditions. It should
be noted that CBCT was not available to
the clinicians at the time of the surgery.
Nowadays, preoperative examination
using CBCT provides valuable information
for the diagnosis and treatment of endodontically compromised teeth. Furthermore, the case report has shown that the
microsurgical approach under the high
magnification of the operating microscope, together with the use of dedicated
ultrasonic tips and biocompatible material, was crucial for the long-term success
of the treated tooth.

INTERVIEW
with — Dr. Francesco Maggiore

Q: Dr. Maggiore, you are considered a prominent expert in the field of endodontics, what
is the state of endodontics today?
A: Endodontics is a very solid discipline
and represents one of the most fascinating specialties in modern dentistry. The
technological and scientific achievements
of the past decades have been enormous.
For years, the goal of the specialty has
been to raise the bar of endodontics, that
is the standard of the routine root canal
therapy performed by both general dentists and endodontic specialists. Probably
now we are confident in saying that the
bar has been raised and many endodontic treatments once considered challenging are actually properly managed by specialists and by well-trained general
dentists.

trying to detect the apical constriction.
It was the era of what I call “tactile endodontics”—everything relied on fingers.
Nowadays, under proper magnification
provided by the operating microscope,
we can clearly see the exact number and
location of root canals, and using an apex
locator, we can precisely detect the apical
constriction. With the right skills and
training, the use of the operating microscope allows the operator to have each
step of the procedure under visual control. This can be accomplished by microscope users, both endodontic specialists
and general dentists alike. This is what I
term “visual endodontics.”
The scientific advancements are many,
including the knowledge of the anatomical variation of each tooth and the histological response of the human body to
different materials or biomaterials used
in endodontics. Scientific advancement
is the understanding of why, when and
how an endodontic file breaks and eventually how to prevent separation. Scientific advancement is also the awareness
that we are dealing with a sophisticated
biofilm complex rather than with single
bacterial species. This has given rise to
the prominent role of irrigation protocols
and modalities in everyday practice.

Q: What have the major advancements in
endodontics been? You mentioned technological and scientific achievements.
A: Yes, not only has technology advanced,
but science has too. Electronic apex locators, operating microscopes, nickel–
titanium rotary instruments, warm guttapercha filling techniques, CBCT and
bioceramic materials are only some of
the technological innovations that have
drastically changed the way endodontics
is practiced today compared with a few
years ago. In the past, practitioners had Q: What are the differences between general

[45] => Editorial_03.indd
The scientific advancements are
many and include knowledge of the
anatomical variation of each tooth,
the histological response of the
human body to different materials,
and the biomaterials used in
endodontics.

A: There are many differences and probably different commitments. A general
dentist has to provide the full range of
treatments for his or her patients, including endodontic treatment. This is a considerable task. In the U.S., the majority
of root canal therapies are actually performed by general dentists and this is
probably true everywhere around the
globe.
General dentists should be confident
in providing primary endodontic therapy,
that is, conventional endodontics. They
should take advantage of the technological innovations in endodontics and use
them to their best ability. They should also
be aware of what can be achieved in the
hands of a specialist, that certain treatments are feasible, that many endodontically compromised teeth can still be saved
and have a good long-term prognosis.
Endodontic specialists complete
advanced education in endodontics
through a postgraduate program. Generally, they limit their practice to endodontics. They provide conventional endodontic treatment, but mainly treat
challenging cases of complex anatomy,
multirooted teeth, traumatized teeth,
endodontic retreatments and endodontic microsurgery.
Many patients would like to retain their
natural dentition for as long as possible.
Endodontic specialists can provide a wide
range of treatments in many cases. Communication between general dentists and

Interview

Endodontics

endodontists is very important for successful patient management. In this
regard, case selection is a key factor for
a general dentist. In fact, many general
dentists know that, in certain clinical situations, the best service they can provide
to their patients is to refer them to the
specialist. A cautious general dentist
knows also when the case has to be
referred, before it is too late, that is,
before a perforation occurs or before an
instrument separation ruins his day. Even
in these challenging situations, however,
very often, a specialist can still save the
tooth. This is probably one of the commitments of an endodontic specialist, to
shift the prognosis of an endodontically
compromised tooth.
Q: What is the aim of your course in the
Clinical Masters™ Program in Endodontics?
A: The purpose of the course is to share
with participants our clinical experience
and knowledge. Most of my everyday clinical work focuses on retreatments, nonsurgical and surgical. Over the years, we
have identified which instrument or
approach works best in the particular clinical situation. Participants will be guided
through treating complex clinical cases
and learning new technologies, materials
and techniques step by step, keeping in
mind the philosophy of a safe and efficient
approach.
Thank you very much for the interview.

Q: How have technological advancements
changed oral implantology since you first
started practicing in this field?
A: Implant dentistry is changing at a rapid
rate, primarily driven by the results of
current research and the advancement in
technology and products. Only by updating our knowledge and skills constantly
will we be able to keep pace with current
trends.
When I started, there were no tapered
implants, implants with internal hex, advanced surface technologies, computerguided surgical stents, drill stoppers or
other such useful tools. I would say the
most useful tool in our armamentarium
these days is CT imaging. Today’s oral implantology clinicians have the advantage
of cone beam volumetric imaging. CT
technology allows us to visualize the patient’s anatomy and pathology like never
before. With these images, we can
measure the exact distance available for
implant placement below or above certain
anatomic landmarks, measure the exact
bone density, measure precisely the width
of the available alveolar ridge and select
the most suitable locations for the
planned implants. This leads to improved
planning and reduced morbidity and reduces our liability.

INTERVIEW
with — Dr. Louie al-Faraje

Q: What sets the California Implant Institute apart from its competitors?
A: Oral implantology is a complex discipline. Many factors must be taken in consideration when developing a treatment
plan involving dental implants. These factors include the patient’s anatomy; the
patient’s general health; the patient’s bone
density; horizontal and vertical spaces of
occlusion; the soft-tissue biotype; parafunctions (if any); the smile line; the patient’s age, sex and size; opposing dentition
and the location of the implants in the
mouth (posterior vs. anterior placement).
The California Implant Institute offers the
most comprehensive dental implant training program in the world, covering all
areas that are pertinent to oral implantology. The extensive live-patient surgical
component of the master’s program is
unique. Our curriculum and world-famous
faculty make ours the most sought after

through in-class lectures, hands-on laboratory sessions, online webinars and live
surgical demonstrations.
Module 2 is the hands-on cadaver module,
in which participants improve their clinical
skills by performing advanced and complex procedures on human specimens.
Module 3 consists of the live-patient surgical training programs held at the institute’s Baja office in Rosarito, Mexico. All
dentists and patients are shuttled from
San Diego to the Mexico site. The participants take a total of four live-patient externships of six days each. Each externship
includes 3–4 hours of treatment planning
each morning. Course material and surgical DVDs are provided before each program to enhance the learning experience.
Module 4 offers the unique opportunity
for participants to shadow and assist one
of the institute’s prosthodontists on-site.
During this module, the participants are
exposed to complex cases, treatment
planning for those cases, occlusion design
and proper hygiene protocols for implant
patients. Other topics include documen-

tation of implant cases, the informed patient consent process, capturing the necessary extraoral and intraoral photographs
for precise implant treatment planning,
digital smile design for aesthetic and complex cases, and dental laboratory training
for immediate implant provisionalization.
Module 5 provides live-patient oral sedation training.
Module 6 is a five-day module covering a
wide range of topics related to CAD/CAM
and computer-guided surgical training,
with a hands-on workshop.
Module 7 is the academic and research
component of the program. Dentists are
encouraged to make use of the institute’s
resource center throughout in order to
complete the following academic assignments:
– Watch 50 surgical videos on the institute’s private YouTube channel
– Complete the research/literature review
assignment
– Provide documentation for five clinical
cases:
– Two single-implant fixed cases
– Two multiunit implant cases (bar
overdenture and locator overdenture
will fall under this category)
– One full-arch fixed implant case.
Q: What have previous participants said
about the program?
A: “The surgical externship courses were
an incredible learning experience for me.

What to see and do
Como is a very small old town and the best
way to get to know it is by exploring its narrow passages, old streets, quaint markets
and piazzas, stopping to enjoy a cappuccino on the terrace of one of its many
cafés.
The remarkable eleventh-century Romanesque Basilica di Sant’Abbondio has a
beautiful fresco series inside the apse and
a university occupies what was once the
cloister.
Lake Como’s shores feature a varied
landscape of fields, forests, imposing
rocks, charming villages facing the lake
and magnificent mansions with beautiful
gardens, particularly from Cernobbio to
Gravedona and Bellagio. The following include only some of the innumerable sights:
The middle of Lake Como, where its three
branches come together, offers a spectacular view of the whole promontory of
Bellagio, of the northern Grigna mountains overlooking Valsassina, and of the upper basin against the backdrop of the Alps
if the skies are clear. It has the mildest
climate and can be reached by boat.

Besides the glorious views of the Lecco
branch of the lake, which turns southwards, there are natural springs, like
Fiumelatte, described by Leonardo da
Vinci, and the impressive Orrido di Bellano
(gorge), situated not far from the Renaissance Villa Monastero at Varenna.

BUCCOLINGUAL IMPLANT
POSITION AS A
CONSEQUENCE OF THE
ABUTMENT SHAPE
— A paradigm shift

Introduction
Implant rehabilitation in the esthetic zone,
especially in the upper arch, has always
posed a number of challenges. Although
high survival rates for implants in this
region are well established, the new concept of success that involves soft-tissue
integration depends on several factors.
The pink esthetic score, white esthetic
score and implant esthetic score1-3 are
indexes usually used to evaluate the
esthetic success of an implant rehabilitation. Many factors play an important role
in the esthetic outcome of any implantsupported restoration. Among some of
the major keys to success are an awareness
of the possibility of sudden resorption of
the buccal plate (bundle bone), along with
accurate 3-D implant planning and positioning.
Many publications have addressed the
problem of buccal plate resorption4, 5 and
a recent literature review6 investigated
the magnitude of dimensional changes in
alveolar hard and soft tissue occurring for
up to 12 months after tooth extraction in
humans. The review found that, six months
after tooth extraction, horizontal bone
loss ranged from 29 to 63%, and vertical
bone loss ranged from 11 to 22%.

Advanced
Implant Esthetics

Article

If not promptly and correctly addressed,
this phenomenon may compromise the
final esthetic restorative result and even
affect implant survival. Stability of the
alveolar bone is paramount for maintaining the stability of the surrounding softtissue and guaranteeing a high level of
esthetics over time.
Regarding implant positioning, several
papers have offered guidelines regarding
optimal 3-D positioning. However, since
the most commonly used finishing line for
restorative abutments is the horizontal
type, guidelines for implant positioning
have been conceived exclusively for that
kind of geometry, but what if the abutment
has a vertical rather than a horizontal finishing line?
The close relationship between the
implant position, the abutment finishing
line geometry, and the crown angles and
contours is evident. The aim of this paper
is, thus, to provide recommendations based
on clinical evidence regarding the buccolingual implant position in the esthetic
zone whenever a feather-edge (shoulderless) abutment is chosen. In such cases,
new guidelines should be taken into consideration to ensure a better soft-tissue
response.

(a) In the mesiodistal
direction, the implant
should be placed
1.5–2.0 mm from adjacent

other implants.
(b) In the apicocoronal

below the midfacial aspect
of the free gingival margin.
(c) In the buccolingual

Implant position in the esthetic
zone
The optimal implant position and diameter
for the esthetic zone have been investigated extensively, with many authors proposing different approaches. Buser et al.,
attempting to identify the ideal implant
position, stated that, in the mesiodistal
dimension, the implant should be positioned no closer than 1.0–1.5 mm to the
adjacent root surface(s);7 between two
adjacent implants, the mesiodistal distance
should be within 3.0 mm. However, when
applying platform-switching, placement
of implants closer than 1.5 mm to the
adjacent tooth has been deemed acceptable and capable of maintaining the bone
peak.8
In the apicocoronal direction, Tarnow’s
assumption that “a maximum of 5 mm
distance from the alveolar crest to the
contact point is necessary to obtain correct soft tissue esthetics in natural teeth”9
has been verified also for implants.10 Choquet stressed the importance of the apicocoronal position for preserving papillae
and found in a retrospective study that,
when the distance between the contact
point and the bone was 5 mm, the papilla
was present in 100% of the cases. More
properly, the platform of the implant
should be located 2–4 mm below the

Implant Esthetics

midfacial aspect of the free gingival margin.11 Bashutski12 and Grunder13 agree that,
in the buccopalatal dimension, the implant
should be inserted to preserve at least
2 mm of buccal bone.
Factors affecting mucosal recession
around single-tooth immediate implants
have also been evaluated in a systematic
review.14 The authors suggested that, in
highly esthetic cases, undersized implants
should be selected and placed at the cingulum to enhance soft- and hard-tissue
growth (Figs. 1a–c).

Importance of the biotype
One prerequisite for managing implant
restorations in the esthetic zone is the
presence of thick soft tissue surrounding
the implant. Gingival biotype is used to
describe the thickness of the gingival tissue
in the faciopalatal dimension and it is classified into two main categories: thin and
thick.23 The difference between the two
biotypes is defined by the visibility of a
periodontal probe through the gingival
tissue: If it is visible, the biotype will be
regarded as thin; if it is not visible, it will be
classified as thick.
A study performed by Kan et al. analyzed
the dimension of the periimplant mucosa
around two-stage maxillary anterior singletooth implants in humans after one year
of function. The study showed a greater

periimplant mucosal dimension in the presence of a thick periimplant biotype compared with a thin biotype.24
It has also been suggested that a direct
correlation exists between gingival biotype
and susceptibility to gingival recession after
surgical and restorative procedures. There
is agreement in the literature regarding
the influence of soft-tissue thickness on
implant survival and long-term success. Fu
et al. have proposed an approach to increasing soft-tissue thickness through the
esthetic triad and PDP management, in
which “P” is the implant position, “D” is the
implant design and “P” is the prosthetic
design.15 They indicate as key factors the
use of platform-switched or parallel-walled
implants, more palatal and apical implant
placement, and concave prosthetic designs
to reduce periimplant bone and softtissue loss.

Abutment shape and contour
Working on the abutment shape and contour has been one of the present authors’
main tasks in recent years, with a specific
focus on the portion of the abutment

58 — issue 2017

located below the gingival level. The
implant–abutment contours can be divided
into two separate portions: the critical
contour (the area of the implant abutment
and crown located immediately apical to
the gingival margin) and the subcritical
contour (located apical to the critical contour). These two entities will exist provided
that sufficient running room (defined as
the distance from the implant neck to the
free gingival margin) is present. Both the
critical and the subcritical contours, if properly modulated and shaped, may be used
to modify the esthetic outcome of the
restoration.16
As already summarized, to prevent buccal bone resorption, the literature suggests
placing the implant at the cingulum of the
future restoration14 or 1.5–2.0 mm palatal
to the incisal margin of the central maxillary
incisor.13 However, this approach can lead
to problems that may jeopardize the
esthetic outcome and the survival of the
implant. For one thing, the crown contour
created by such placement is substantially
different from what exists in nature. In
natural dentition, the tooth contour is basically formed by two separate entities: the
emergence profile and the cervical contour.

Crown contour and emergence
profile
The emergence profile is straight and corresponds to the part of the tooth emerging from the gingiva. The cervical contour
is convex and located at the bottom of
the gingival sulcus, corresponding to the
area where the enamel overlaps the cementum at the cementoenamel junction
(Figs. 2a & b). This convexity has been
identified by Wheeler,17 who referred to it
as the cervical ridge or cervical contour,
and it has the function of holding the
gingiva under definite tension.

The amount of this convexity is given by
the value of the emergence angle (EA),
which is defined as “the angle formed by
the junction of a line through the long axis
of the tooth, and a tangent drawn to the
coronal of the tooth as it emerges from
the sulcus”18, 19 (Fig. 3). The EA was recently
measured on natural maxillary extracted
teeth19 and it was found to have a mean
value of 15°.
In implant rehabilitation, the value of
the EA and the convexity of the cervical
contour are influenced by the buccopalatal
position of the implant. The more palatal
the implant placement, the greater the
EA and cervical contour. Since the main
task of the restorative dentist is always to
make artificial crowns appear to be and
function like a natural tooth, the artificially
recreated angles and contours should be
reproduced as closely as possible to nature.

Changing the implant position
according to the abutment shape
For the past decade, the present authors
have been working mainly with shoulderless abutments (both for implants and
natural teeth). In doing so, it has become
apparent that implant placement following
the conventional guidelines often results
in the fabrication of crowns with subcritical contours that differ greatly from those
of a natural tooth. Figures 4a–g show an
implant placed according to the conventional guidelines (i.e., at the cingulum of
the future restoration) and restored using
a shoulderless abutment. This resulted in
a final restoration with an excessively convex EA that in the short term (one year)
was already causing the surrounding soft
tissue to react adversely.

Fig. 6a

Conventional guidelines for implant
placement have been conceived and
widely adopted for restorative abutments
made with a horizontal preparation
(shoulder or chamfer). However, as can
be seen in Figure 5, placing an implant
with a shoulderless abutment with a cingular (Fig. 5b) or palatal (Fig. 5c) position
would lead to a crown with an EA and
cervical contour far from the anatomical
ones described by Wheeler and Du.17, 20
However, when the implant is slightly
more buccally positioned, as in Figure 5a,
the EA and cervical contour look much
more natural and physiological.
Currently, there is no evidence that
an excessive artificial cervical contour
is either beneficial or detrimental to
soft-tissue stability, even though, according to the authors’ clinical experience,
some adverse soft-tissue behavior has
been noted when such crown contours

Fig. 6b

are designed (Fig. 4f). However, increasing the convexity of the subcritical contour will create an undercut which will
ultimately make cement removal, for a
cemented crown restoration, much more
difficult. Leaving residual cement inside
the gingival sulcus is more likely to occur
with restorations such as those illustrated
in Figures 5b and c, thus placing the
implant at great risk of periimplantitis
and possible loss21 (Figs. 6a–c).
Whenever a shoulderless preparation
is the geometry of choice, it is therefore
advisable to change the position of the
implant in a more vestibular direction,
with the long axis corresponding to the
incisal edge of the future restoration
or of the adjacent teeth. This position
will allow the creation of physiological
crown profiles and angles closely re sembling those of a natural tooth 22
(Figs. 7–9).

62 — issue 2017

Whenever a vertical (shoulderless) preparation has been chosen for the definitive
implant abutment rather than a horizontal (shoulder or chamfer) preparation,
changing the buccolingual position of
the implant is recommended, especially
in the esthetic zone. The long axis of the
implant should correspond to the incisal
edge of the future restoration or of the
adjacent teeth, assuming that 1.5–2.0
mm of the buccal bone can be maintained. This is the only position that

enables fabrication of a restorative crown
with a cervical contour resembling, as
close as possible, what nature originally
provided. It also eliminates problems
with cement removal, greatly reducing
the incidence of iatrogenic periimplantitis and making hygienic procedures
much easier. Scientific data substantiating these observations are lacking. Therefore, randomized and prospective clinical trials are necessary.

XA ABUTMENT
Developed in collaboration with BORG center, the new
XA range of prosthesis comes from the biological
concept that correlates healthy soft tissue and longlasting hard tissue. The presence of a micro-threading
at the basis of the abutments guides the fibroblast
growth and stimulates the production of collagen,
supporting the bone regeneration thanks to the tapered
morphology of the abutment and helping in preserving

ABOUT
THE STEIGMANN INSTITUTE
COURSES
Dr. Marius Steigmann, Germany

Clinically, it is a tremendous challenge to
create natural gingival esthetics after
immediate or delayed implant placement.
Stability of the soft tissue during implant
surgery is of major importance for the
implant site and adjacent teeth. For cases
in which only the tooth is compromised
and not the soft-tissue or osseous form,
a flapless surgery can be performed. In
cases of localized horizontal or vertical
deficiency, dehiscence or fenestration,
another approach is necessary. From a
prosthetic prospective, the soft-tissue
architecture around implants has to be
similar or close to that of the natural
tooth. While the dental laboratory can
deliver the best functional and esthetic
work, it will be harmonious only if the
soft-tissue dimensions are maintained or
developed surgically or with the help of

the prosthetic reconstruction. Singleimplant placement has proved to be more
predictable than multiple-implant placement. In the case of multiple implants and
delayed loading, it is possible to form a

soft-tissue profile with provisionals or
proceed directly to the final reconstruction. This is done with the help of a wax-up
on the final metal frame to control the
pressure of the soft-tissue intraorally.


[69] => Editorial_03.indd
Soft-tissue management
for bone augmentation
Different tissue biotypes react differently
to surgical trauma. For this reason, we
have adapted the surgical approach to the
biotype (tissue thickness) specific to each
patient and the location in the oral cavity.
The tissue thickness dictates the way it is
manipulated for high-volume augmentation. Thick biotypes can be managed in a
conventional manner. However, thin biotypes require new surgical approaches
with specific instruments. This course will
describe step by step the gain of softtissue for tension-free closure even in
cases of reduced soft-tissue thickness.
The course will define predictable
soft-tissue manipulation around implants
according to soft-tissue biotype. Learning
from our clinical experience in soft-tissue
manipulation, we can adapt soft-tissue surgery. We need to graft more, to manipulate
the soft tissue, to treat each particular
case.
There is little data in the literature on
adapting surgery according to soft-tissue
thickness. Most articles describe the same
kind of surgery for all cases, with no distinction between biotypes. With this in
mind, we have to adjust surgery to the
tissue conditions for better soft-tissue closure in cases of grafting and for better
esthetics. This means individualized flap
design for every tissue type. The next step
will be the development of instruments,
but more than that, of implant surfaces
and biomaterials that address not only the
bone but also the soft tissue. Adapting
therapy to soft-tissue biotype is changing
the way we approach implant dentistry.

Soft-tissue management
for the esthetic zone
Function and esthetics with implant treatment depend on case selection, surgical
planning and prosthetic reconstruction.
Each of these has evolved dramatically
over the years. The latest implant designs
increasingly help the clinician in achieving
these goals in the esthetic zone. Incorrect
flap design leads to dramatic failure in this
sensitive soft-tissue zone. The course will
address the requirements for modern flap
design according to the necessary amount
of bone and soft-tissue regeneration.

Prosthetic soft-tissue
development in implant
dentistry
The main purpose of this course is to
explain, demonstrate and teach softtissue development around implants with
the help of prosthetic components in
fixed, single- and multiple-implant
placement.
The course will cover abutment design
for ideal soft-tissue support, pontic design
for esthetic soft-tissue development,
emergence profile design for the crown
and abutment, different wax-up modalities, esthetic try-ins for different therapeutic phases, crown margin definition,
gingival management with temporaries,
and mock-ups.

Soft-tissue complications
and full-arch restoration
With the increasing number of implants
being placed in the esthetic zone according to immediate or delayed protocols, we
face soft-tissue complications like recession of the soft-tissue and papillary loss.
There are no predictable methods documented in the literature regarding how to
increase the soft-tissue height for the
papillae or correct recessions around
implants.
The course will demonstrate individualized approaches to correct papillary loss
in the esthetic zone using modern flap
design techniques. Furthermore, increasing soft-tissue thickness and moving the
soft tissue coronally after recession around
implants through surgery and prosthetic
methods will be described.

Advanced
Implant Esthetics

Soft-tissue management:
Vertical augmentation
Vertical bone loss represents a major surgical challenge in the implant treatment
of the posterior mandible, owing to anatomical factors and technical difficulties.
Proper management of the soft-tissue is
crucial for success of any regenerative
procedure: A complete and stable closure
of the flaps during healing is essential to
prevent contamination and infection and
allow for undisturbed graft healing and
incorporation. This prerequisite can be
accomplished only if buccal and lingual
flaps are sufficiently released, in order to
obtain a passive coverage of the augmented area, stabilizing it with tension-free
sutures. In the posterior mandible in particular, the use of conventional periosteal
incisions is not always sufficient for a
proper buccal flap passivation, often
being limited by anatomical factors.
Over time, bone augmentation has
moved from highly specialized clinics into
the dental office. With the help of modern
grafting material, the augmentation
volume in the dental office has increased
year by year. However, the main issue
remains soft-tissue closure for highvolume augmentation, especially in the
posterior mandible and posterior maxilla.
We have developed special flap designs
and suturing techniques specific to location to address this ongoing problem of
soft-tissue management. The participants
will learn about and practice soft-tissue
closure according to location.

INTERVIEW
with — Drs. Rodríguez Ciurana & Vela Nebot
Q: Drs. Vela and Rodríguez, you refer to
your newest XA abutments, developed with
Sweden & Martina, as paradigm shifting.
Could you please explain what has led you
to this point?
A: The main concern of the clinician is to
minimize the inexorable bone resorption
and apical migration of the soft tissue that
involves multiple problems, including
esthetics and the survival of the restoration in the medium and long term owing
to periimplantitis. We consider that our
approach is a paradigm shift because using
XA abutments and a suitable rehabilitation
protocol not only avoids apical migration,
but also promotes coronal migration of
bone and soft tissue over time. This means
esthetic improvements, as well as protection against periimplantitis.

plant tissue. The evolution of the concept
reflects different phases of our work over
the years. The BORG Center was established in 2012, and the BORG members
began their clinical research in 2004, at
which time we followed the standard protocol: an implant without platform switching (PS), an abutment with an anatomical
profile imitating the shape of the tooth
(divergent shape) and a protocol entailing
multiple disconnections. However, with
this approach, the tissue tended to apical
migration.

74 — issue 2017

Q: Apical migration means gingival recession. Did this not compromise the esthetics?
A: Of course. In fact, gingival recessions
gave rise not only to esthetic risk but also
to the risk of periimplantitis. We therefore

topics and be led by world-famous practitioners in different parts of the world.
The offering includes courses on basic
implantology in Germany and China, a
workshop on the MULTIFIX solution in
Portugal and a course taught in Turkey on
the fundamentals of aesthetic smile design.
Dr. Eric Van Dooren, a key opinion leader
in implant dentistry and the co-developer
of MIS’s V3 implant, will be teaching a
course on the VCONCEPT in his training
center in Antwerp in Belgium, where he
has been conducting courses and workshops for the past 12 years. He explained
that the purpose of the center is to offer
courses with a focus on periodontology,
prosthetics and implantology that give

participants the opportunity to witness
live surgeries. Participants enjoy high-tech
audio-visual and are able to take advantage
of live streaming.
The latest series of courses will focus
on the integration between prosthetic and
surgical implant treatment concepts and
will highlight soft-tissue management in
the aesthetic zone, both through theoretical material and a live surgery demonstration.
Van Dooren added: “Since we are focusing on new concepts and trends, the
VCONCEPT really helps us in explaining
that modern implant dentistry is changing
compared to a few years ago.” Van Dooren
also incorporates the MIS MGUIDE guided

Participants who have taken Van
Dooren’s courses in previous years have
provided positive and enthusiastic feedback. The hands-on experience with the
MGUIDE system has led to a great response
from dentists, who have begun using these
methods in their practices since attending
the course.
Van Dooren plans to continue lecturing
on these topics and incorporating the V3
