【摘要】 本文采用Auto-CAD软件及螺旋CT扫描技术与有限元应刀分析方法相结合．考虑颞下颌关节（temporomandibularjoint．TMJ）的材料非线性及关节内接触问题等非线性特征，在活体基础上建立TMJ三维非线性有限元模型，以计算和分析正中咬合时关节内的应力分布和位移情况。更多还原

【Abstract】 Combining spiral CT scanning technology with three-dimensional finite element method, togetherwith Auto-CAD software, a three-dimensional nonlinear finite element model with nonlinearcharacteristic such as nonlinear material and contact relationship in the joint was developed fromin vivo for calculating and analyzing the stress distribution wit.hin the human temporomandibularoint (TMJ) during centric occlusion in order to simulate and analyze the stress distribution anddisplacement of the human TMJ.更多还原
