Current surgeon dentists heavily rely on their experiential judgments from the oral plaster casts and the medical images of patients to determine the positions and directions of implant fixtures and to perform drilling tasks during dental implant surgical operations. This approach, however, may cause some errors and deteriorate the quality of dental implants. Presented in this thesis is an approach of 3D dental implant simulation in order to alleviate the shortcomings of the conventional approach. In the presented approach, 3D simulator is constructed to visualize dental implant information obtained from medical images, and a tangible interface device is combined to provide the realistic experience of the information. The dental implant information can be obtained by three phases: In the first phase, we constructed 3D mesh models for jawbone, teeth and nerve curves from dental images with the help of software Mimics. In the second phase, we selected suitable types of implant fixtures from fixture database and determine the positions and directions of the implant fixtures from the 3D mesh models and the dental images with the help of Simplant software. In the third phase, we constructed the 3D model of a tool guiding the drilling operation based on the geometry of the jawbone and the teeth of interest. The dental implant information is visualized and combined with the tangible interface device in the downstream application phase. In the dental implant 3D simulation, the user can see and touch the 3D models related with dental implant surgery. Furthermore, he or she can experience drilling paths to make holes where fixtures are implanted. A preliminary user study shows that the presented approach can be used to provide dental students with good educational contents. For future work, it is expected to utilize the proposed approach in clinical studies of dental implant surgery.
