Construction of Advanced Dental Operation System using Commercial-Based GPGPU and Haptics

In this research, using parallel processing and Z-buffer in GPGPU, we calculate an intersection between a tooth (several kinds of hard and soft materials in the tooth) and a dental bar, and then cut the tooth (and also determine force and moment) by the barefficiently. Secondly, we construct a dental tool such as a bar by a 3-D printer, and we can get several kinds of real operations by the tool between two commercial-based tactile feedback devices. Finally, 3-D stereo image of tooth and bar is reflected front the doctor by a transparent mirror. Consequently, the doctor can operate several dental surgeries in the virtual world as same as he/she does in the real world.
