Haptic AR Dental Simulator Using Z-buffer for Object Deformation
Dental surgical simulator could be one of the efficient tools to learning and practicing dental surgical skills. To these simulators, the visual and tactile feedback is desirable to be processed in real time. And, in the dental operation, the hand position during operations is one of the skills to learn and practice. Therefore, we develop the dental surgical simulator which use virtual tooth surface model for processing real time rendering. And we develop a display system which allow users to training dental operation by a right hand position.. The tooth model is deformed by cutting and drilling operation using haptic device. And the display is set close to user’s hand position and shows combined image with virtual tooth model as a surgical target and a real tooth model as other parts of the patient dental model. The system uses a collision detection and deformation method by using Z-buffer for virtual objects. This method enables users to view the complex shape of virtual tooth model by the surgical operation tasks and practicing dental surgical tasks. We developed prototype system and confirmed about the capability of our system.
