正常与3D打印下颌骨的模型建立与数值对比分析

In order to study the stress of the mandible under different occlusal methods and different bite forces, based on the existing head CT data, the mandible was extracted through the medical software Mimics and the three-dimensional model was established, and the mandible was analyzed by redrawing the mesh, constructing the contour line, constructing the curved surface, constructing the grille, and fitting the surface. Through to the normal mandible and 3 d printing titanium implant restoration of mandibular were analyzed, and the results show that: in the 3 d printing on the titanium alloy implant restoration of mandibular adult male before and after loading teeth can withstand maximum force, mandibular by stress are less than normal mandible by stress.
