Recently, the progress of dental science is so remarkable and clinical technics have become increasingly advanced and complicated. However, effective instruction of these clinical technics among students in a time-constrained schedule is very difficult to achieve. Because of this, there is a need to develop a rational training system based on simulated clinical procedures.
In this study, we attempted to develop devices, models and aids for dental practice, and to introduce computers into dental education for assessment and simulation.
1. A questionnaire survey about the basic phantom practice of conservative dentistry was performed to all dental schools in Japan.
2. Visual and kinetic aids for periodontal education were created using three dimensional computer graphics, and their effectiveness were evaluated.
3. A virtual cavity preparation system was attempted to be built.
4. Artificial jaws and teeth models for dental simulation practice were produced and refined.
5. Automatic assessments of prepared cavities were tried using computer graphics.
6. Operator's position was analyzed for introduction of dental simulation systems.
7. Problems of dental simulation systems were discussed.
8. Dental simulation systems to gauge the taught skills such as cutting pressure during cavity preparation and instrumentation of root canal preparationwere also designed to provide the necessary feedback to the trainees.
Since the dental simulation system was developed only recently, and it relates to all dental procedures, new problems were noted during the conduct of this two-year study. It has been found that continuous study to develop more efficient devices and teaching methods is exceedingly necessary.
