1st SIG Dental CADCAM symposium at IADR conference in
Washington 2000
Title:
"Advances in Dental CADCAM"

The
advent of CAD/CAM technology to dentistry is revolutionizing
the practice of prosthodontics. Increasingly sophisticated software
and automated fabrication will replace many of the current labor-intensive
techniques. This symposium will review advances in various aspects of
dental CAD/CAM technology. Different commercially available CAD/CAM
systems and materials will be discussed with respect to clinical
application. All-ceramic posterior crowns have significant failure rates
(10-30%) after five years, which can be related to luting cement, core
elastic modulus, and can be modeled by contact fatigue testing. Machining
operations during CAD/CAM processing can create damage that accelerates
ceramic fatique; high strength ceramics and layered structured may provide
improvements. Design criteria for CAD/CAM restorations will be reviewed
and compared to conventional restorations. Both glass ionomer and
resin-based composite cements provide adhesion to ceramic, but behave very
differently. The interaction between layer thickness, shrinkage stress,
viscoelasticity, modulus, and strength for a thin cement layer will be
discussed with respect to durability of CAD/CAM rstorations. It is hoped
that this symposium will lead to more research focus on dental CAD/CAM and
bring together individual researchers active in this area. Published

On April
7th 2000 the Special Interest Group CADCAM had its first
founding organisational meeting.

“Dental CADCAM Systems

The
practical use of CAD/CAM technologyin the industrial world is remarkably
advanced in recent years. It contributes the production of the materials
in high quality and low cost. The production systems of dental prosthesis
with CAD/CAM technology have been widely developed and clinically applied
in a field of dentistry in the world. The prosthetic preparation have been
depended on the skill of the dental technician for long period and the
provided dental prosthesis are not always fulfill the all of requirements
in some cases.
The application of CAD?CAM prosthesis production systems enables
mechanical production of high quality dental prosthesis which was the
complicated and time taking work of dental techniciansCAD/CAM systems were
outlined. Prof. Dan Nathanson (USA) Dr. Kazuhiro Hikita (Japan) and Prof.
François Duret (France) discussed the present status and future
perspective of dental CAD/CAM systems in USA, Japan and Europe
respectively. Published: J Dent Res 80, 2001, IADR Abstract #1748, p. 745.

Title:
" Present Status of Dental CADCAM – What’s next?"
Computerized
dentistry in the form of dental CADCAM is more and more closing the
gap with traditional restorative and prosthetic dentistry and
validation of the present status dental CADCAM has become imminent.
A
wide spread survey on dental CADCAM technology research based on
several information sources will be presented.
Software
architecture and quality are key to the acceptance of computerized
dentistry and to achieve maximum benefit for the dentist and the
patient. Research on model-driven architecture, re-usable software
components and interoperability within the context of daily dental
practice is needed for succesful implementation.
Development
of standards for dental CADCAM modalities such as digital impression
systems, electronic patient records and communication protocols are
necessary to achieve harmonization in dental CADCAM.
A
wide range of new materials have become possible due to developments
in CADCAM- technology. Research into the effects on the integrity
and long-term durability of automated fabrication methods is
presented and new research challenges explored.
