计算机辅助设计建立上颌全口义齿三维边界元模型

3D Modelling of Upper Jaw Full Denture Using CAD

使用光波调制三维自动化测量系统测得上颌全口义齿基托三维数据，输入计算机，利用计算机辅助设计（ＣＡＤ）技术构造三维实体模型，用网格自动剖分模块自动形成边界单元信息及各节点的坐标值，应用ＣＡＤ技术排牙建模；模型仿真性强，可用于全口义齿生物力学研究和教学演示。

The 3D data of upper jaw denture base was acquired through a 3d optical wave modulation measurement system. With those data CAD was used to generate the 3d model, and the meshes and the boundary element information were generated automatically. the teeth were arranged with the help of CAD. This model was recommended for full denture biomechanics research and classroom demonstration.
