| Abstract: | OBJECTIVE: A 3D geometric simulation of mandible with dental arch from CT has been obtained in this study. METHODS: This process uses automatic system assisted with interactive action to get 2D contour data from CT images,then 3D wireframe model and solid model were obtained by using CAD/CAM software Pro-E(USA) and DELCAM(UK). RESULTS: 3D solid model of mandible with dental arch were presented which can be fully edited. CONCLUSION: This model can be applied to further educational and clinical researches such as RP,biomechanics simulation in prosthetic dentistry.The processes of simulation has wide applications in clinical practice of dentistry and dental education. |
