摘　　要：对志愿者头颅部进行螺旋CT扫描,利用Mimics软件进行实体模型的重建,优化后导入Ansys软件中赋值及网格划分,建立左侧下颌第一磨牙缺失的包含微型种植体、直丝弓托槽、牙列、牙周膜、牙槽骨的下颌三维有限元模型,实验模拟与临床基本相符。A volunteer was scanned by spiral CT, the Dicom format images were imported into Mimics software to reconstruct 3-D mandibular model,then optimized by Geomagic and meshed in Ansys software. A good geometric precise three-dimensional finite element model was constructed. The displacement of dentition was similar with clin- ical situation by computer.
