| Research Abstract |
In this age of advanced and complicated clinical dentistry, knowledge acquisition through books and training methods using manikins cannot provide adequate training results in diagnoses, treatment planning and communication with patients. For example, dentists who have received training through manuals and manikins will be faced with tremendous technical and psychological burdens when engaging in actual therapy. The goal of this project is to develop the new computer-aided clinical dentistry educational system based on virtual reality (VR) technology that assumes diverse situations encountered in a clinic and can promote the efficiency of dental training. A UNIX workstation specially designed for VR system, including multiple CPUs for parallel processing to generate rendered 3D graphics and stereophonic sounds in real time, was installed. The original output system, i.e.a head-mounted display (HMD), has been updated to the see-through type HMD with low weight and high visual quality. P

ositional information of user's hand was transmitted with a replica of dental drill head, while the three-dimensional position information is sensed with three coils in a magnetic environment. In addition, a digitizing system providing seven links with seven degrees of freedom like the human arm was developed to evaluate hand movements. This digitizer has lately been replaced by a new system with six arms based on the parallel mechanism to improve the locating accuracy. The dental operating simulations for caries cavity removal and tooth preparation originally developed on this system have been sophisticated both invisual and sound effects to represent the real as practical as possible. The advantages of the application using virtual reality, providing 1) supplementing intermediate and manikin-based training in the process of practical education, and 2) enables training in the risk management as when the patient's tongue moves suddenly, encouraged dental trainees effectively to understand the skill of clinical dentistry. Our further studies should be continued to complete the appropriate feedback system and to spread the range of simulation in dentistry. Less
