Prof. Zvi Artzi is an Associate Professor
in the Department of Periodontology at the School of Dental Medicine, Tel Aviv
Zvi has published over 80 articles and research abstracts in
peer-reviewed leading journals in Periodontology and Oral
Implantology. He has lectured extensively at international
conferences. Professor Artzi's current main research topics are
related to osseointegration, bone regeneration, bone substitutes
and advancing surgical modalities.
Why bovine bone mineral is a reliable and predictable biomaterial in intra-oral applications.
The use of bone substitutes is a key factor that influences bone regeneration. Ideal
materials should enhance bone formation with appropriate porosity, structure,
biocompatibility and sterility. The use of substitutes can reduce the need for
autogenous donor bone whilst maintaining long term success of augmentation
procedures. Bovine bone mineral is biocompatible and osteoconductive and has
proved to be appropriate for use in socket preservation, ridge
deficiency, sinus augmentations and repair of periimplant bone
destruction. Both histological and controlled clinical trial data will
be presented supporting the use of bovine bone substitutes.
Professor Nick Donos is the Head & Chair of Periodontology and
the Director of the Division of Clinical Research at the UCL-Eastman
Dental Institute in London. His research track record is
mainly on GTR and GBR and clinical trials in implantology.
Professor Donos has published extensively and is a member of
the editorial board of leading peer-reviewed journals. Nick is the
Director of the ITI Scholarship Centre at the UCL-Eastman
Dental Institute and the Education Delegate of the ITI UK &
Synthetic bone grafts and GTR. From experimental studies to
clinical application in conjunction with dental implants.
The use of different type of bone grafts in combination with GBR aim predominantly
in avoiding the collapse of the flexible barrier membranes into the bone defect. Very
often there is a dilemma regarding the most appropriate type of bone graft to beused.
During the lecture, the experimental studies evaluating the bone
regenerative healing with GBR and synthetic bone grafts as well as
its clinical application will be discussed.
Dr Marco Esposito is a Senior Lecturer in Oral and Maxillofacial
Surgery and the Editor of the Cochrane Oral Health Group.
Marco graduated with honors in dentistry at the University of
Pavia, Italy in 1990 and was awarded a PhD in Biomaterials from
the Göteborg University in 1999. He has authored more than
80 scientific publications in international peer-reviewed
journals. Marco's main research interests are the assessment
of the effectiveness of various therapeutic interventions with
particular emphasis on dental implants.
Comparison of xenografts and synthetic materials
Data from an updated Cochrane systematic review of randomized controlled clinical
trials comparing the efficacy of xenografts and synthetic bone materials in various
clinical applications related to implant dentistry will be presented and critically
Dr Christian Mertens is the Consultant and Assistant Medical
Director, the Clinic for Oral and Maxillofacial Surgery at the
University of Heidelberg. Dr Mertens is a 2001 graduate of the
Faculty of Dental Medicine of the University of Bonn. He is a
Senior Oral Surgeon, a Certified Implantologist and a serving
university lecturer. One of his specialties is augmentative
surgery and the surgical treatment of the atrophic maxilla.
Synthetic bone graft materials for sinus augmentation.
In posterior edentulous maxilla with high degrees of alveolar ridge resorption
maxillary sinus floor-augmentation techniques are used to increase bone volume.
Nowadays synthetic bone graft materials rather than autogenous bone gain more
importance in daily work and show predictable results concerning
conversion into bone in relativly short time. An overview of existing
materials, advantages, disadvantages, limitations and clinical
cases will be presented.
Dr Michael R. Norton is a Specialist in Oral Surgery and is
Visiting Professor at Marquette Dental School in Milwaukee,
USA. He was recently awarded a Fellowship by the Royal College
of Surgeons, Edinburgh for his contribution to the field of
implant dentistry. Michael is a graduate of the University of
Wales School of Dental Medicine. Michael lectures
internationally and is widely published. His literature includes
the Quintessence textbook: Dental Implants - A Guide for the
General Practitioner (1995)
Does xenograft provide an efficacious alternative to autogenous
bone for GBR?
With autogenous bone still considered the gold standard, questions remain about the
efficacy of bone substitutes as an alternative therapy. In addition there are questions
about the nature of defects and whether all defects respond in a
similar manner. This presentation will focus specifically on the use
of bovine xenograft as a material for augmentation using the
principles of guided bone regeneration.
Dr Frank Schwarz is currently the Assistant Professor in the
Department of Oral Surgery at the Heinrich Heine University in
Duesseldorf. His doctorate focused on periodontal treatment
with an ER:YAG laser and in 2002 he received the young
researcher award for his work on Lasers in Dentistry, after
which he worked as an Associate at the Department at the
Ludwig Maximillians University in Munich.
New perspectives in bone regeneration.
The ideal bone substitute should possess, at least some physicochemical properties,
such as biocompatibility, osteoconductivity, resorbability, and steadiness in order to
support wound healing following GBR procedures. Most recent
studies have emphasised that the outcome of bone regeneration
might also be influenced by either the implant surface or
biocoating using osteogenic proteins of the transforming growth

of Restorative Dentistry at the University of Loma Linda (USA)
and is a Program Director Post Graduate of Oral Implantology at
the University of Corsica. He received his DDS at the University
of Paris VII in 1982. Pascal is an international speaker and
author of several papers in the field of bone regeneration and
maxillary sinus grafting. Dr Valentini has a private implant
dentistry practice in Paris.
Sinus Grafting : Long Term Results with xenografts.
The patients included in this report have been treated using anorganic bovine bone
with a 1 or 2 stage technique, according to the volume of residual
bone. The overall implant survival rate was 90.1% after a mean
functioning period of 10 years. Late failures, attributable to chronic
bacterial infection were observed only on cylinders.
