采集患者牙、颌参数、结合计算机辅助设计（ＣＡＤ）在计算机中重建患者整体牙、颌的三维计算机模型，结合数学理论中曲线、曲面拟合算法，确定各点、线位置，设计构造出所需义齿各个表面的形状。利用三维有限元法对所设计义齿进行受力校核分析。反复修改数据，直至得出义齿的最佳设计参数，利用这些参数编制加工程序，经数控设备即可完成义齿的计算机辅助制造（ＣＡＭ）工作
The patient’s teeth and jaw parameters were collected, and the three-dimensional computer model of the whole dentition and jaw was reconstructed in computer with computer aided design (CAD). Combined with the curve and surface fitting algorithm in mathematics theory, the position and position of each point and line were designed. Need denture the shape of each surface. The three - dimensional finite element method was used to analyze the force of the designed denture. Repeatedly modify the data until the denture obtained the best design parameters, the use of these parameters preparation of processing procedures, CNC equipment to complete the denture’s computer-aided manufacturing (CAM) work
