摘　　要：螺旋CT扫描获取志愿者的上颌CT图像,利用Mimics 10.0、Geomagic Studio、ANSYS 13.0软件处理及运算,建立舌侧矫治内收上牙列阶段的实体模型。根据微种植体与舌侧牵引延长臂的位置不同,共建立2个实体模型。对实体模型进行网格划分,并初步加载工况进行验证,验证结果符合相关研究结论及临床实际情况。Cone-beam computed tomography was applied to scan volunteer＇s maxillary. Mimics 10.0,Geomagic Studio and ANSYS 13.0 were employed to develop 2 volume models,based on the position of micro-implant and lever-arm,during retracting upper dentition by lingual appliance. The effectiveness of 3-D finite element models was validated by loading working conditions after dividing FEM mesh. The validation results were consistent with the related research conclusion and actual clinical situation.
