RATIONALIZATION AND IMPROVING EFFICIENCY OF DENTAL CLINICAL EDUCATION USING SIMULATION SYSTEMS

近年来，口腔科学的进步是如此显著，临床技术也变得越来越先进和复杂。然而，在有限的时间内在学生中有效地讲授这些临床技术是非常困难的。因此，有必要开发一种基于模拟临床流程的合理培训系统。在本研究中，我们尝试开发用于牙科实习的设备、模型和辅助工具，并将计算机引入牙科教学中进行评估和模拟。结果：1.编制了修复牙科和牙周病领域的计算机辅助培训手册，并对其效果进行了评价。改进了三维计算机图形学在牙周教育中的视觉和运动辅助手段。改进了虚拟空洞制备系统。制作并完善了用于牙科模拟实习的人工颌骨和牙齿模型。使用计算机图形对已准备好的龋齿进行自动评估。为引入牙科仿真系统，对操作者的体位进行了分析。讨论了牙科仿真系统存在的问题。建立了操作员位置反馈给学员的自动评估系统，并对其效果进行了评估。由于牙科模拟系统是最近开发的，它涉及到所有的牙科操作，在为期三年的研究中发现了新的问题。人们发现，继续研究开发更有效的手段和教学方法是非常必要的。

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. Computer aided training manuals were created in restorative dentistry and periodontics fields, and their effectiveness were evaluated.2. Visual and kinetic aids using three dimensional computer graphics for periodontal education were improved.3. A virtual cavity preparation system was improved.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. Automatic assessment system of operator's position for feedback to the trainees was created, and it's effectiveness was evaluated.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 three-year study. It has been found that continuous study to develop more efficient devices and teaching methods is exceedingly necessary.
