摘　　要：颞下颌关节的生物力学研究对理解颞下颌关节病的发生、发展具有重要意义。有限元方法可以分析颞下颌关节各组织受到外力或者发生形变后组织内部的应力和应变情况,但其复杂而且细致的解剖结构导致构建有限元模型的研究总是耗时、昂贵和不可重复。为寻求一种更为快捷、精确的下颌骨三维有限元模型建立方法,提高颞下颌关节有限元建模精度,针对模型与实体几何相似性、生物力学环境仿真模拟等相关因素进行综述。The biomechanical studies on the temporomandibular Joint （TMJ） are of great importance to understand the origin and progression of TMJ disorders. The finite element method can be used to analyze stress/ strain distribution patterns in TMJ tissues after application of force or deformation. However, due to the delicate and complicated anatomical structures of TMJ, the modeling research was always time-consuming, expensive and non-repeatable. To explore a more rapid and accurate method for establishment of 3D finite element model of TMJ, the relevant factors such as geometric similarity, biomechanJcal environment simulation for improving the accuracy of TMJ finite element modeling were summarized.
