Construction of three-dimensional finite element model of human maxilla by MIMICS and CATIA software

目的:利用MIMICS和CATIA软件辅助建立包含方丝弓矫治器的上颌三维有限元模型。方法:对志愿者头颅部进行多层螺旋CT扫描,利用MIMICS、CATIA软件完成托槽及三维实体模型的重建,在此基础上通过ABAQUS软件建立包含方丝弓托槽的上颌三维有限元模型。结果:建立了高精度的包含方丝弓托槽、上颌牙列、牙周膜、牙槽骨的上颌三维有限元模型。结论:利用MIMICS和CATIA软件辅助建模,提高了模型的精确性和建模效率。

Objective：To explore an easy and precise method to reconstruct 3D finite element model of the maxillary with Edgewise appliance based on MIMICS and CATIA.Methods：By using multi-slice spiral CT scanning,MIMICS and CATIA software were used to complete the reconstruction of three-dimensional solid model of maxilla.Results：A good geometric precise three-dimensional finite element model of the maxilla and dentition was constructed.Conclusion：MIMICS and CATIA software can improve the efficiency of establishment of the 3D finite element model.
