Precautions for
using zirconia
implant abutments
By Moustafa N. Aboushelib, DDS, MSc, PhD,
and Rien van Paridon, DDS, PhD

Giuseppe Vercellotti, co-owner
and chief operating officer of
Piezosurgery Incorporated.

What sets
Piezosurgery
devices apart
from others?
Interview: Piezosurgery’s
Giuseppe Vercellotti
By Sierra Rendon, Managing Editor

Implant Tribune recently had the
honor of interviewing Giuseppe Vercellotti, MSc, co-owner and chief operating officer of Piezosurgery Incorporated. Vercellotti’s father, Tomaso
Vercellotti, is the inventor of the revolutionary technology.
What is Piezosurgery® and where
does it originate from?
Piezosurgery is a patented ultrasonic
technology specifically engineered for
bone surgery. Piezosurgery was developed in the late 1990s by Tomaso Vercellotti, MD, DDS, and Mectron Medical
Technology to overcome the limits in
precision and safety of traditional bonecutting instruments.
This technology employs the vibration of piezoelectric ceramics to cut
bone but not soft tissues. Despite the
fact that they are based on similar
physical phenomena, Piezosurgery is
so technologically advanced that it has
no elements in common with normal
ultrasonic ablation devices. The operation of this ultrasonic surgical device is
driven by sophisticated software, which
controls and optimizes the ultrasonic vibration necessary for bone cutting. The vibration is generated in the
handpiece and exerts its cutting action
through insert tips specifically designed
g IT page 2B

The introduction of zirconia to
the dental field opened the design
and application limits of allceramic restorations.
Thanks to its high strength and
fracture toughness, long-span posterior restorations are now possible
with high accuracy and success rate.
Additionally, its white color allows
better reproduction of the required
color especially in the anterior zone.
These properties make zirconia
an interesting material for the construction of implant abutments and
superstructures.1
The fabrication of zirconia
implant abutments utilizes stateof-the-art CAD/CAM technology,
which uses patients’ models for the
production of an individual customized abutment.2
Moreover, the CAD phase allows
accurate positioning and angulation of the zirconia abutment ensuring obtaining the best esthetics.
The fabrication of zirconia
implant abutments is complicated

Moustafa Aboushelib)
by the problem of providing adequate
fixation to the implant body.
For titanium abutments, the fixation screw exerts direct pressure on
the abutment, which in turn is provided with external or internal hex to
provide connection with the implant
body.
On the other hand, zirconia is a
brittle material and friction between
the fixation screw and the internal
surface of the ceramic abutment could
produce high internal stresses that

retention with the implant body.
could lead to unexpected fracture.3
This problem is solved by insertion
of a friction fit internal metallic nut
(Procera zirconia abutment for Straumann implants), which is equipped
with an external hex for establishment
of proper contact with the implant
body (Fig. 1).
Additionally, the fixation screw
interlocks with the metallic nut during tightening procedure (Fig. 2). This

for drilling, cutting and remodeling
mineralized tissues. The cutting action
produced by the unique modulated
ultrasonic vibration of Piezosurgery is
micrometric (extreme precision) and
selective (no trauma to soft tissue);
additionally, combined with irrigation,
the vibration produces a “cavitation
effect” that helps to keep the surgical
site sterile and bloodless.
Over the years, as the result of Mectron’s continuous technological innovation, more than 50 insert tips have been
designed and engineered to provide
surgeons with the best cutting tools
for each anatomical situation. Indeed,
Piezosurgery allows one to perform
bone surgeries with high precision,
greater respect for soft tissues, greater
visibility and enhanced healing.
What are the advantages of Piezosurgery in implant and bone surgery?
The surgical advantages of Piezosurgery are many and truly remarkable.1
First, Piezosurgery delivers high precision. The ultrasonic wave employed
by the device is a “microvibration,”
which compared to the macrovibrations
of traditional bone-cutting instruments
makes this technology incredibly more
precise and safe. Indeed, the cutting
action does not require as much pressure and can be interrupted at any time
to check the progress of the surgery.
AD

Implant Tribune | June 2010
The cutting action is then resumed
and refined as needed, with precision
and safety for both the surgeon and
the patient. Second, Piezosurgery’s cutting action is harmless to soft tissues.
Thanks to the specific resonance range,
the device is extremely effective on
mineralized tissues but totally harmless
to soft tissue, allowing for a safety level
never experienced before.
This feature is obviously of crucial
importance when operating in proximity of delicate soft-tissue structures, such
as blood vessels, nerves, mucosa, etc.
Third, thanks to its dual-wave technology, Piezosurgery delivers maximum
intraoperatory visibility.
When the “hammering effect” produced by the wave modulation on the
insert tip hits the irrigation solution, the
latter is converted in a fine spray. The
sprayed molecules of the irrigation fluid
hit the cutting site, cool it down and
produce a temporary hemostatic effect,
allowing for maximum visibility during
surgery. Once terminated, the surgery
bleeding resumes, hence starting all
biological processes leading to proper healing. Lastly, one of the greatest
advantages of Piezosurgery is the fact
it is gentler to the tissues and, in fact,
induces faster healing. Histological and
biomolecular studies have shown that
compared to traditional techniques, the
use of Piezosurgery is not only characterized by minimal postoperative bone
loss but actually promotes faster heal-

ing.2,3 In my opinion, this incredible feature makes Piezosurgery the preferable
instrumentation for most bone surgical
applications.
How did your father, Dr. Tomaso
Vercellotti, get involved with Piezosurgery?
Prompted by the limitation in precision and safety of traditional bonecutting instruments, my father pioneered the use of piezoelectric ultrasonic frequencies for bone surgery.
Upon realizing that the effectiveness
of conventional ultrasonic instruments
in cutting bone was extremely limited,
he set off, in conjunction with Mectron
Medical Technology, to develop a new
technology that would allow overcoming such limitations. Their joined efforts
resulted in the creation of Piezosurgery,
a technology that has truly revolutionized the way we approach bone surgery.
My father’s clinical and scientific
efforts were truly indispensable to make
Piezosurgery into a surgical revolution.
First, he wanted to ensure that this
new technology would truly benefit
surgeons and patients alike, improving surgical predictability and reducing
morbidity and complications.
To this goal, my father engaged in
several research collaborations with
clinicians and institutions across the
world. In addition to studies on cutting
efficacy of the technology and bone
healing response in animal models, fervid clinical research activity has arisen
immediately since the initial distribution of the Piezosurgery technology.
To date, Piezosurgery is the only
piezoelectric surgical technology that
has been demonstrated to be effective
and successful by the clinical community through peer-reviewed publications. The number of publications on
Piezosurgery increases every day, testimony of the clinicians’ understanding
of the truly revolutionary nature of this
technology.
The results of this research, published in more than 70 scientific articles,
prove the advantages of Piezosurgery
and make a compelling, evidencebased argument for its adoption in a
variety of bone surgical applications.
Why did he get so passionate about
this procedure?
My father realized immediately the
technology he had developed had
remarkable characteristics and understood he had an opportunity to simplify
and improve a variety of surgical procedures. Along with several international
colleagues, for several years he has
been developing new surgical protocols
and procedures. As a result, an entirely

design is associated with the problem of generation of internal stresses,
which could lead to unexpected fracture of the zirconia implant abutment.
This article will evaluate the fracture causes of several broken zirconia implant abutments. Fractographic
analysis of the broken segments will
allow recognition of the location and
site of the critical fracture.

Fig. 2a: A broken maxillary
premolar was extracted and
implant was immediately inserted.

Fig. 2b: Procera zirconia abutment.

Fig. 2c: Procera zirconia veneered
crown inserted over the zirconia
abutment.

Case presentations: Case 1
A broken zirconia implant abutment
was sent by the treating dentist for
fracture analysis. Patient’s records
indicated that the patient complained
of loosening of the implant-supported
zirconia-veneered crown (#21).
The treating dentist also complained that the internal metallic nut
AD

lost friction contact with the zirconia
abutment and that he had to re-assemble the components before screw fixation. The abutment was fractured after
two incidents of screw loosening.
The same problem led to fracture
of the second abutment, after which
the dentist decided to insert a tita-

nium abutment.
Scanning electron microscopic
examination indicated that the abutment was fractured due to pressure
from the metallic screw nut.

The solution
Once the metallic nut has lost friction

fit with the zirconia abutment, it cannot be correctly reinserted inside the
abutment, and areas of friction contact
between the improperly assembled
components could lead to generation
of high internal stresses causing fracture of the zirconia implant abutment
as was reported for the two examined
abutments. A new abutment should be
used in such case.

Case 2
This next case featured a broken zirconia implant abutment. SEM analysis
revealed that it was an angled abutment, which corrected the tilt of an
implant replacing a maxillary lateral
incisor. The entire buccal wall was
fractured beneath the temporarily
cemented zirconia-veneered crown.

The solution
Zirconia is a brittle ceramic material that must be used in adequate
thickness to gain full potential of
its high strength. A minimal wall
thickness (0.5-0.7 mm) is required
in the entire structure of the zirconia
implant abutment.
This thickness must be increased in
areas of high stresses to avoid unexpected fracture. Tilt correction resulted in over-reduction of the buccal wall
(0.3 mm thickness), which resulted in
fracture of the weakened segment.
To reduce possibility of fracture,
it is recommended to use a metallic
abutment for correction of angle of
insertion.

Case 3
The final case featured a broken
veneer porcelain from a Procera zirconia superstructure. This new design
combines both the implant abutment
and the framework of the restoration
in one single structure, thus reducing
the number of components the dentist
uses during the prosthetic phase.
This single component zirconia
structure does not utilize an internal
metallic nut for achieving contact with
the implant body.
On the contrary, this single component super structure utilizes the fixation screw to obtain direct fixation to
the implant body.

The solution
Using single component superstructures has several advantages as they
simplify the handling procedure, do
not require anti-rotation feature and
reduce the number of structural interfaces of the entire restoration. On
the other hand, they require careful
design to provide adequate support for
the veneer ceramic.

metallic nut, the friction fit system
lost adequate retention after a short
service time in the mouth leading to
loosening of the inserted restorations.
According to complaints of the
treating dentists, it is not recommended to reassemble the metallic nut and
tighten the fixation screw as this will

not result in reliable retention of the
restoration. In such case, it is recommended to insert a new abutment
from the manufacturer using patient’s
records.
Moreover, over-tightening the fixation screw beyond the recommended
torque could lead to generation of

wedging forces inside the zirconia
abutment.
The screw head could exert pressure on the metallic nut leading to
spreading of its vertical walls.
Using a confirmatory X-ray before
tightening the fixation screw and
keeping to the recommended torque
could prevent such problem. For cases
with marked angle correction, it is
recommended to use a metallic abutment in order to avoid over-reduction
of the axial walls.
On the other hand, using single
component zirconia implant superstructure, which is composed of zirconia abutment and the framework as
one component, could facilitate easier
handling and simplify the insertion
procedure due to reduction of the
components used.
Moreover, careful design consideration of the requirements of both the
abutment and the zirconia framework
is mandatory to ensure good function
of each element. Lack of adequate
support beneath the veneer ceramic
or over-reduction of the axial walls of
the zirconia abutment could lead to
unexpected fracture. IT

new surgical discipline based on the
advantage of Piezosurgery’s unique
features was developed. This new discipline, known as Piezoelectric Bone
Surgery (PBS), has notably simplified a
variety of clinical applications and has
allowed surgeons across the world to
perform procedures that would have
been almost impossible with any other
instruments.
Thanks to the intense clinical
research, many surgical techniques
have been radically simplified and predictability has increased, with dramatic
reduction of patient morbidity.4,5 As an
example, the use of Piezosurgery is
changing evidence-based medicine in
the surgical studies of the maxillary
sinus, where membrane perforation
rates have been decreased from 30 percent to 7 percent.6
What is the best and least indicated use of the Piezosurgery?
Piezosurgery is extremely versatile and
can be used in a great variety of surgical applications. Indeed, through the
sapient use of osteotomy, osteoplasty
and drilling techniques, the device
allows one to perform bone surgery
even in the most difficult anatomical
situations. Examples of procedures that
can be performed with Piezosurgery
include extractions, sinus lifts, ridge
expansion, bone block harvesting, bone

chips harvesting, accelerated surgical
orthodontics, nerve lateralization, retrograde endodontics, crown lengthening and implant site preparation in delicate anatomical situations. In general,
Piezosurgery is ideal for all surgeries
that require fast, precise and safe bone
cutting. Our device is not indicated
for procedures that involve cutting soft
tissues, poorly mineralized bone structures and dental enamel.
Are there other units in the dental
industry, and what is the difference
between the technologies?
Following the invention of Piezo-surgery by Tomaso Vercellotti and Mectron Medical Technology, several companies, recognizing the great potential
of our technology, seized the opportunity to enter the market with imitations
of our device. Despite other companies’
claim that all devices are equal, that
is simply not the case. In my opinion, while this may be a commercially
sound strategy, it is a true disservice to
the clinical community. Unfortunately,
equating all devices creates confusion
and leads clinicians exposed to inferior
devices to conclude that the technology
per se is not valid.
However, it is important for clinicians to be aware that Piezosurgery is
not a generic term and does not refer
to any technology or application. Piezosurgery refers to the only patented,
evidence-based piezoelectric technol-

ogy for bone surgery. When clinicians
try and use our technology, they realize that imitations do not compare to
it at all. As a testimony to this fact, all
major opinion leaders in the United
States employ and endorse only the
real Piezosurgery technology.
There are experiences and insights
in the technology that only the original
developer can have, and that cannot
be simply retro-engineered. The imitation units utilize different ultrasonic
frequencies, different power levels and
inferior insert tip designs. In this latter
regard, for instance, no other device
has saws that are as thin and fast as
ours. Indeed, Mectron Medical Tech-

nology developed a proprietary manufacturing process that takes months to
complete, and the resulting insert tips
are unrivalled in terms of precision and
performance. Because no other company could replicate this process, the performance of imitation devices in cutting
bone thicker than a few millimeters is
unsatisfactory for most clinicians who
perform heavy-duty bone surgery.
A major difference between our
technology and its imitations is that
only Piezosurgery is clearly and
unequivocally proven and supported by
scientific research. To my knowledge,

there are only a handful of publications
relative to other technologies, and none
proves substantial equivalence to Piezosurgery in regard to biomolecular, histological and clinical results. In a world
where medicine is constantly striving
to improve, only evidence-based technology should be trusted and incorporated in daily practice. Unfortunately,
sometimes commercial interests and
strategies confound the public, hence
hindering the progress of the discipline.
As a scientist, I understand that a discipline’s progress is achieved through
trial and error, independent verification and hypothesis testing. Therefore, I
always encourage clinicians to research
Piezosurgery thoroughly and independently, seeking the advice of reputable
experts and always keeping in mind
what is best for their patients.
Lastly, at Piezosurgery Incorporated, we are experts dedicated full-time
to the Piezosurgery technology only,
and truly believe that our products can
improve the quality of life of both surgeons and patients. To fulfill this goal,
we value clinical education and customer service. For instance, when a
clinician incorporates Piezosurgery in
his or her practice, our product specialists provide in-office training for
the staff and the surgeon and assist to
surgeries. Additionally, on a monthly
basis Piezosurgery Incorporated offers

complimentary clinical, hands-on
courses across the United States to all
of its customers. In our experience, best
results using Piezosurgery are obtained
through education.
In short, despite the fact that several companies attempted to produce
competitive products, the Piezosurgery
technology remains unrivaled, and is
the only one supported by research and
education.
What are some of the recent innovations?
Over the years, Dr. Vercellotti and
Mectron Medical Technology have
continued to perfect the Piezosurgery
technology to make it applicable to a
wider array of surgeries. This constant
evolution of the product is clearly seen
in the development of new insert tips
for implant site preparation and microsaws. Implant site preparation tips
— available in a series up to 4 mm in
diameter — are used in the preparation of the implant site in anatomical situations when placing implants
with conventional tools is risky if not
almost impossible. The microsaws are
designed for use in thin ridge splitting
and accelerated surgical orthodontics.
These saws are 11 mm long and have
a section of 0.35 mm, hence allowing
extreme precision in the osteotomy at
the same time sparing bone when it is
precious to save!
Another recent innovation was

the development of the Piezosurgery
3 device, now available in the North
American market. This new device has
a specific function optimized for implant
placement, new and simpler settings,
and is up to 30 percent faster than the
previous model. Additionally, thanks to
the development of more sophisticated
software, the Piezosurgery 3 device has
improved self-diagnostic and safety features, which allow the surgeon to operate with confidence.
Any other directions you and your
company are involved in?
As a company focused on bone surgery, Piezosurgery Incorporated is constantly seeking ways to improve the
surgical experience for clinicians and
patients alike. We are currently preparing to launch the Piezosurgery Medical
device in North America. The Piezosurgery Medical device is the most sophisticated and advanced device for Piezoelectric Bone Surgery and brings the
advantages of our unique technology
in a wider array of surgical procedures.
Specifically designed for hospital-based
surgical procedures, the Piezosurgery
Medical device is intended for use in
a variety of medical specialties, such
as neurosurgery, otolaryngological surgery, minute orthopedic surgery and
oral and maxillofacial surgery. IT
