Three-dimensional digital reduction of jaw opening and closing movement
Objective To explore a three dimensional digital displayed method of mandibular movement, and provide a basis for the virtual reality of mandibular motion. Methods 1 case of male adult, with the integrated dentition, and no temporomandi-bular joint disorders was used in this study. The independent three-dimensional digital jaw model was reconstructed with CT image in Mimics11.0. The three-dimensional digital reduction of jaw opening and closing movement with six degrees of freedom was set up in Autodesk 3dsmax 8.0. Results Through the three-dimensional digital jaw opening and closing movement, the location between the upper and lower jaw, dentition, occlusion and the structures of the temporomandibular joint could be demonstrated clearly. Conclusions Adopting autodesk 3dsmax 8.0, virtual reality of jaw movement with six degree-of-freedom and 3D digital jaw models can be built, which is feasible to quantify and visualize the course of the mandibular movement.
