Objective: This study was to simulate the terminal hinge movement of the mandible with virtual reality (VR) technologies. Methods: Centric relation was recorded and casts were mounted on a simple articulator. The 3D data of the casts were measured by Atos II (an optical measuring system). The terminal hinge movement was simplified and decomposed to a series of position transform (rotation) and simulated by real-time updating display. Centric relation was reposited by efficient collision detection method. Results: The centric relation position was reproduced and the terminal hinge movement was simulated. Distributing of occlusal contact regions and the cutaway view of occlusal contacts were detected. Conclusion: This method was feasible and may be applied for dental occlusion diagnosis.
