摘要:

目的:利用知识库开发一套实用的全口义齿计算机辅助设计/制作(CAD/CAM)系统。方法:由三维座标测量机(3DCMM)获取无牙颌、托等模型的三维信息,运用B样条方法建立全口义齿的数学模型。共设置8个功能模块:测量模块、数据转换模块、曲面造型模块、基托生成及编辑模块、排牙方案及编辑模块、结果输出模块、动态模拟模块和管理模块。结果:建立由3DCMM,8个功能模块和数据库组成的全口义齿计算机辅助设计软硬件系统。完成全口义齿计算机辅助设计及三维显示。结论:本系统的建立为全口义齿CAD/CAM系统的开发奠定了基础。

Abstract:

Objective:The purpose of this study was to develop a practical CAD/CAM system with knowledge databases for complete denture.Methods:A three-dimensional coordinate measuringmachine (3DCMM) was used to collect three-dimensional information of edentulous models and bite plates and the mathematics model of complete denture was established using B-Spline method. This system was established by suing eightfunctional models: the measuring model, the converting data model, the constructing curve- surface model, the producing base and the editing model, the arranging artificial and the editing model, the outputting income model, the imitating dynamic model and the managingmodel.Results:(1) The soft and hard system of a computer aided complete denture design (CACDD) was established, including 3DCMM, 8 functional models and databases. (2) ACACDD system and the three-dimensional demonstration were completed.Conclusion:This system lay down the foundation for setting up the computer aided complete denture design/manufacturing system.
