【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。
[Abstract]:In order to be able to apply the invisible tooth appliance more reasonably and effectively, to control the size and area of the orthodontic force, and to prevent the orthodontic force from acting on the tooth that does not need to be moved because of its deformation, The finite element method is used to analyze the deformation and optimize the design. A new finite element method is proposed to establish the three-dimensional finite element model of the full dentition stealthy orthodontic appliance with unequal thickness, and the boundary conditions are determined. The flow chart of the optimal design of the invisible appliance is also worked out. Taking the oblique movement of the central incisor as an example, the corresponding appliance was analyzed and optimized in order to achieve a better effect.
