To develop a system of computer aided complete denture design (CACDD).
After 3 dimensional measurement, data process and making model of a edentulous model, artificial teeth and the maxillomandibular bite plate, on the position of centric relation, the artificial teeth were arranged according to the principle and demand of the complete denture's teeth arrangement. The relation of teeth and occlusion were adjusted by Affine and Projection transformation.
(1) The maxillomandibular visual base on the position of centric relation were made, its mathematics model is B-Spline curve surface of the double third power. (2) The artificial teeth arrangement and 3 dimensional show of the complete denture were achieved.
This system can provide a feasible tool for a computer aided complete denture design and teaching.
开发一种计算机辅助全口义齿设计（CACDD）系统。
对无牙颌模型、人工牙及上下颌咬合板进行三维测量、数据处理并制作模型，在正中关系位，按照全口义齿排牙的原则和要求排列人工牙。通过仿射变换和投影变换调整牙齿与咬合关系。
（1）制作了正中关系位的上下颌可视基托，其数学模型为双三次B样条曲面。（2）实现了全口义齿的人工牙排列及三维显示。
该系统可为计算机辅助全口义齿设计及教学提供一种可行的工具。
