摘要

目的　建立下颌骨髁突缺损有限元模型，研究新型人工颞下颌关节的应力分布及位移改变。方法　运用Mimics、Geomagic、Solidworks、ANSYS软件建立含完整牙列的下颌骨右侧髁突缺损有限元模型并分析新型人工颞下颌关节在模拟咬合力加载的情况下假体及下颌骨硬组织的应力分布和位移情况。结果　下颌骨整体等效应力值均低于20 MPa，最大形变值不超过0.05 mm。结论　新型人工颞下颌关节能避免过大应力导致的假体断裂和骨质吸收，具有良好的生物力学特性。

Abstract

Objective　Mandibular condylar defects in the finite element model is established to study the new artificial temporomandibular joints stress distribution and displacement of the change. Methods Mimics, Geomagic, Solidworks, ANSYS software were used to establish complete denture mandibular condylar defects on the right side of the finite element model and analyze the new TMJ condylar prosthesis in simulation of the bite force load of mandibular condylar prosthesis and hard tissue stress distribution and displacement.　Results　The whole Mandibular equivalent stress values were smaller than 20 Mpa, the maximum deformation value was smaller that 0.05 mm.　Conclusions　New artificial temporomandibular joints can avoid prosthesis fracture and bone absorption caused by excessive stress , and has a good biomechanical properties.
