摘　　要：颞下颌关节的健康与咀嚼、吞咽及发音等基本生理功能密切相关。颞下颌关节紊乱与关节内部异常的应力分布可能存在一定联系。然而,常规手段难以直接测量颞下颌关节内部复杂的应力及应变情况。动态三维有限元分析因其精确、无创等特点成为研究颞下颌关节生物力学的主要方法,但不同建模方法的几何相似性及力学仿真度存在明显差异。本文将从颞下颌关节的几何模型构建、材料属性及接触关系、动态载荷的加载方式等方面对颞下颌关节的动态三维有限元模型构建方法作一综述。The healthy temporomandibular joint(TMJ)is of vital importance to basic physiological functions such as mastication,swallowing,and speech.Temporomandibular joint disorders are possibly related to abnormal stress distribution in the TMJ.However,it is not feasible to directly measure the complex stress and strain distribution patterns in the TMJ by conventional measurements.Dynamic three-dimensional finite element analysis has become the main method to study the biomechanics of TMJ due to its accurate and non-invasive nature.However,there are significant differences in the geometric similarity and degree of mechanical simulation between different modelling methods.In this paper,the geometric model construction,material properties,contact relationship,and the kinematic loading of TMJ are reviewed.
