Abstract
Contact state of upper and lower teeth is very important for diagnostic treatment of occlusal disorders. This paper discusses an actual occlusal motion with patient-specific 3D-motion display system. The system uses a patient-specific hybrid model to analyze detailed contact state of upper and lower teeth in eating foods. The hybrid model consists of maxillary and mandibular bone data with cone beam X-ray CT and precise teeth shape data with industrial X-ray CT. The proposed display system clearly shows the trajectories of each tooth and the guide function.
