摘要 目的:建立与种植义齿部件实体具有几何和力学相似性的三维有限元模型。方法:用CaMega光学扫描,建立种植体、基台三维CAD模型,导入ANSYS软件,进行单元划分建立有限元模型,并根据载荷-变形实验数据,调整有限元模型参数。结果:建立的种植义齿三维有限元模型,经试验验证,与义齿实体具有几何和力学相似性。结论:采用光学三维扫描,修正有限元模型参数,建立的种植义齿部件有限元模型,能反映其实体的几何形状和力学特性。该研究是种植义齿有限元分析的基础。 Objective:Establish a 3D FE (finite element) model with geometric and mechanical similaritiy to the physical implant prosthese components. Methods:Use the 3D CaMega optical scanning system, to establish a CAD model of implant and abutment, which is imported into CAE software (ANSYS 11.0) for meshing to establish the FE model,and the parameters of the FE model is then adjusted according to the load-deformation test data. Results:According to experimental data,the 3D FE model of implant prosthese established has the geometric and mechanical similarity to implant prosthese components. Conclusion:The FE model of implant denture components established with 3D CaMega optical scanning and by correcting FE model parameters can reflect their physical geometric shapes and mechanical properties.
