摘要
目的:建立成人上颌中切牙的仿生种植体三维有限元模型,为分析与探讨仿生种植牙的生物力学特性奠定基础。以成人上颌中切牙为标本,通过螺旋CT扫描和计算机图像处理技术,获取中切牙各截面的轮廓坐标数据,再通过CAD技术进行单元网格的自动划分,形成SuperSAP模型数据文件,输入到SuperSAP93有限元专用分析软件后建模。结果:建立了有效的仿生种植牙三维有限元模型。结论:模型的几何相似性、生物力学相似性均佳,可用于仿生种植牙的生物力学研究。
Objective： To establish a three-dimensional finite element model for bionic dental implant of central maxillary incisor, and to lay a basis for analyzing or discussing the biomechanical characteristics of the bionic dental implant. Method： The shape data of the central maxillary incisor in sections can be acquired by helix-CT scan and computer image techniques, and the data file of the SuperSAP model was founded by CAD techniques, then the file was transmitted to SuperSAP93 to establish the model. Results： An effective three-dimensional finite element model for bionic dental implant was established. Conclusion： The geometrical analogy and the biomechanical analogy of the model were quite good, so it can be used to research the biomechanical characteristics of the bionic dental implant.
