摘　　要：为了能够更加合理有效地应用隐形牙齿矫治器,控制其产生矫治力的大小和作用区域,防止因其变形导致矫治力作用在不需要移动的牙齿上,采用有限元法对其进行变形分析和优化设计:提出了一种建立不等厚覆盖全牙列隐形矫治器三维有限元模型的新方法,完成边界条件的确定,并制定了隐形矫治器优化设计的流程。以中切牙倾斜移动为例,对相应的矫治器进行了具体分析和优化,使其达到更好的矫治效果。For the purpose of utilizing the invisible braces effectively, controlling the power and the function area of the orthodontic force, preventing the orthodontic force from affecting the wrong tooth which caused by the deformation, by using the finite element method the deformation and the optimal design of invisible braces is analyzed. And a new method of creating the three-dimensional finite element model is recommended, which is the unequal thickness invisible braces covering the entire teeth. The boundary conditions is determined, and then the procedure of the optimal design of invisible braces is formulated. The middle incisor tilt movement as an example is utilized to analyze and optimize the invisible braces for more effective correction.
