摘　　要：目的尝试一种建立高精度矫治器三维有限元模型的方法,为以后探讨支抗种植体辅助正畸治疗生物力学研究打下基础。方法通过螺旋CT扫描结合Mimics、Abaqus及Catia软件,建立上颌骨-上牙列-矫治器三维有限元模型复合体。结果建立了几何相似性及生物模拟度高的三维有限元模型。结论本实验有限元建模方法有效、灵活、快捷。Objective To develop a new way to construct 3 D finite element model complex of appliance and to lay the foundation of evaluating the effects of an mini -implant anchorage biomeehanics. Methods Finite element models included of maxilla and dentitions with appliance were generated by computed tomography and software of Mimics Abaqus and Carla. Results The model established had good geometric morphology and biological similarity. Conclusion The method of establishing model conducted with CT, Mimics, Abaqus and Catia in this research was efficient, flexible and convenient.
