AO elects Taylor as 32nd president
Aims to lead strategic global course
By AO Staff
D
r. James C. Taylor from Ottawa,
Canada, recently became
the newest president of the
Academy of Osseointegration
(AO) at the organization’s annual
business meeting in Los Angeles.
As the academy’s 32nd president, and
the first from Canada, Taylor succeeds
Dr. Michael R. Norton from London,
England, at the helm of AO.
“I’m honored to have the opportunity
to lead our academy in its global
role of enabling the development,
dissemination and application of
knowledge in the domain of implant
dentistry, for the well-being of our
patients,” Taylor said. “The academy is a
grand constellation of interrelated and
interdependent elements, perpetually
interacting to create a whole that is so
much greater than the sum of its parts,
which makes AO the world’s premier
international academy in the domain
of evidence-based and patient-centered
care in implant dentistry.”
As part of his presidential address,
Taylor outlined his vision for continuing
to move AO forward on its robust
strategic course and highlighted his
upcoming agenda to foster AO’s message
of multidisciplinary and evidence-based
patient care in implant dentistry around
the world.
“I can say from personal experience
that it is rare to assume the presidency of
an organization that is already on a sound
and successful strategic trajectory. This
is a trajectory that I had the privilege of
helping to shape and implement during
the presidencies of my predecessors,
and I plan to stay that course during my
presidency,” he continued.
Looking ahead to his year as president,
Dr. James
C. Taylor
of Ottawa,
Canada.

JOI: Patient satisfaction and clinical data
shape effectiveness of dental prostheses
T
he growing success of dental
implants provides an alternative
to traditional dentures. Implantsupported
fixed
complete
dental prostheses (IFCDPs) are changing
modern dentistry and allowing for a new,
innovative way to treat endentulism
(toothlessness). As more dental providers
move toward IFCDPs, data on both patient
satisfaction and clinical outcomes are
necessary.
Researchers from the University
of Illinois at Chicago and a private
practice in Dallas recently performed
a retrospective study published in
the Journal of Oral Implantology that
focused on patients’ oral health, quality
of life and IFCDP complications. 37
patients with 49 prostheses participated
in this study by completing a written
questionnaire, attending an in-person
interview and having an oral exam of
their IFCDPs.
The synthetic materials contained in
the IFCDPs included 22 metal-acrylic
(MA), 14 retrievable crown (RC), seven
monolithic zirconia (MZ) and six
porcelain-veneered zirconia (PVZ). The
most common complications found for
each compound were: MA had posterior
tooth wear; RC contained fractures
and chipping; MZ contained wear of
opposing restorations (wear on natural
teeth); and PVZ had chipping of opposing
restorations. The researchers deemed
six prostheses as failures, mainly due to
fracturing and chipping. This included
two MA, two PVZ and two RC.
When reviewing patient questionnaires
and interviews, the researchers found
that the overall level of satisfaction
patients had with their prostheses was
high. 87 percent of patients were very to
extremely satisfied, and 89 percent felt
their IFCDPs “looked great.” However, the
PVZ prostheses were shown to have the
most negative effect on patients, while
the MZ had the least.
The chief complaint was functional
limitation with regard to chewing,
differences in speech patterns and
hygiene. The researchers noted, “This
leading-edge study helps clinicians
recognize common problems with
full arch dental implant-supported
prostheses, so that they can provide
predictable results for patients …
“It is clear that patient satisfaction was
closely related to patient expectations
and patient education. By selecting the
prosthesis that best suits each patient,
and by sharing with patients the types
of problems they might have, fewer
complications and greater patient
satisfaction with care is possible.”
This research is limited in its scope of
observed complications as well as the
size of the study group. The researchers
are viewing it as a preliminary study
and verification of outcomes needs to be
conducted with a larger sample size and
more real-time data, vs. a retrospective
analysis.

JOI: Removal of exposed titanium mesh
leads to more successful dental implants
I
mplant dentistry practitioners are
increasingly seeing more difficult
cases of implantation in which they
must first overcome insufficient
bone volume within the upper and lower
jaw. These types of difficult cases have
led to new surgical techniques, such
as utilizing titanium mesh to assist in
guided-bone regeneration.
While this technique can lead to a
successful implant procedure, the use of
titanium mesh has been known to cause
complications in some patients.
Researchers
from
Loma
Linda
University, King Saud University (Saudi
Arabia)
and
Imam
Abdulrahman
Bin Faisal University (Saudi Arabia)
recently published a study in the Journal of
Oral Implantology that introduces a new
method for treating exposed titanium
mesh. Through four case studies, the
researchers show that by removing the
exposed titanium mesh and leaving the
remainder to continue the regenerative
process, dental implantation can be more
effective and successful.
Between 2015 and 2017, four patients
were treated with titanium mesh. The
patients were between the ages of 27 and
50, and each had two previously failed
bone regenerative procedures.
In all four cases, the surgical technique
used to incorporate the titanium
mesh with the bone graft was the
same; however, each patient received a
different type of material or membrane
to cover the titanium mesh. Each patient
also experienced mesh exposure at a
different rate, ranging from one to six
weeks post-operation. The exposed
mesh was removed between four and
10 weeks after exposure occurred. The
remaining titanium mesh was removed
approximately six months after insertion
and one to two months prior to dental
implantation.
In all four cases, the researchers found
that by removing the exposed titanium
mesh and allowing the rest to remain,
the bone volume reached a level that was
adequate for dental implants. Another
benefit of exposure removal was the
creation of a more hygienic space for the
implant. Caring for areas with exposed
mesh caused difficulty and discomfort
for patients, compromising the integrity
of the regenerative site.
“The removal of the exposed part
seemingly did not have a negative effect
clinically on bone integration in the final
volume of the augmented bone, and
allowed for easier hygiene maintenance
by the patient,” said researcher Dr.
Aladdin J. Al-Ardah.
The researchers acknowledge that their
technique has been successful and helps
ensure proper bone regeneration and
hygiene maintenance for dental implant
surgery, but that further analyses are
necessary. Before this technique can be
carried out in routine dentistry, more
clinical research with a greater number of
patients is needed.

Dr. Kenji Higuchi selected as 11th Nobel Biocare
Brånemark Osseointegration Award winner
By AO Staff
D
r. Kenji W. Higuchi, an oral and
maxillofacial surgeon from
Spokane, Wash., is the 11th
recipient of the Nobel Biocare
Brånemark Osseointegration Award.
This annual award bestowed by the
Osseointegration Foundation (OF), the
philanthropic arm of the Academy
of Osseointegration (AO), honors an
individual whose impact on implant
dentistry is exemplary in any or all of the
foundation’s mission categories: research,
education and charitable causes. The
award is made possible by a grant from
Nobel Biocare.
“I am deeply honored. This is especially
gratifying because of my close and
long-term relationship with Professor
Brånemark. It is personally meaningful
to be recognized by the Osseointegration
Foundation for past involvement in
research, education and humanitarian
service, as all these activities have been
of central importance throughout my
career while providing patient-centered
care,” Higuchi said.
OF President Dr. Edward Sevetz
presented the award to Higuchi during
the opening symposium of the academy’s
2018 annual meeting in Los Angeles.
“Dr. Higuchi’s professional and personal
experiences and characteristics qualify
him for being a role model for anyone in
the dental health-care field.
Almost 40 years ago, he developed a close
working relationship with the discoverer
of osseointegration, Swedish orthopedic
surgeon Per-Ingvar Brånemark. Dr.
Higuchi worked side-by-side with Professor
Brånemark and became one of the earliest
surgeons in the U.S. to recognize the
breakthrough of osseointegration and
how it would vastly improve the quality
of the lives of patients,” Sevetz said. “Dr.
Higuchi annually took time out of his own
private practice to coordinate professional
training sessions to ‘raise the bar’ of those
wishing to help patients in their own
locales.”
Higuchi is a diplomate of the American
Board of Oral and Maxillofacial Surgery.
His private practice (Drs. Higuchi and
Skinner PS) emphasizes reconstructive
oral and maxillofacial surgery. Since
1984, he has been the director of the
Spokane Center for Tissue Integrated
Reconstruction. Since 2007, Higuchi
and Professor John Brunski, Stanford
University, have been the principals in
OsseoConception LLC.
He completed his undergraduate
studies at the University of Wisconsin, his
DDS from Marquette University School
of Dentistry and served four years on
active duty in the U.S. Army, including an
Dr. Kenji W. Higuchi, center, was presented with the Nobel Biocare Brånemark
Osseointegration award by outgoing AO President Dr. Michael Norton, left, and Dr. Edward
Sevetz at the recent AO Annual Meeting. Photo/Provided by AO
internship at Letterman General Hospital
at the Presidio in San Francisco. He
obtained his residency with a master’s of
science in oral and maxillofacial surgery
at University Hospitals at the University
of Iowa and has held past full-time and
adjunct academic appointments at that
institution. From 1986-2018, Higuchi
participated in 10 separate multi-center
prospective clinical trials.
“With his humanitarian heart, scienceoriented mind and openly-friendly
personality, Dr. Higuchi is an exemplary
role model to all of us on how to lead our
professional and personal lives,” Sevetz
concluded.
