摘要
采用CT旋转断层扫描法及冠状断层扫描法获取全下领牙种植义齿反领骨各结构连续断面的CT剧像,持结构轮廓均匀放大后描记于透明坐标纸上,输入美国SGI公司IndigoI型计算机,应用I-DEASFEM软件,经数据处理完成三维形态数字仿真模型重过,划分单元和节点,建立三维有限元实体模型。
Consecutive sectional images of the edentulous mandible,the implant-supported complete fixed prostheais andoverdenture weze ohtained by CT scan.The anterior part of the model was scaned in rotating matter getting transaxialimages,while the posterior waa scaned in coranal direction getting cross-sectional images.The outline of each struc-ture was magnified and recorded on the transparent coordinate papers.Input the coordinate values and construct 3-Dsimulation in SGI Indigo I computer aided by I-DEAS FEM software.The model was meshed and boundary condi-tion was set.So the 3-D FE model was conatructed.
