【摘要】 本文介绍了一套可摘局部义齿设计的专家系统,利用三维可视化技术,可直观、立体的显示修复设计效果。论述了三维图形库建立的方法,其中牙列三维模型由从CT获得的二维断面序列重建而成,义齿部件模型由专家在此基础上绘制。另外介绍了知识库设计的方法。最后,给出了两例牙列缺损修复设计的图示结果。更多还原

【Abstract】 This paper introduced an expert system for designing removable partial dentures. The results of denture designing can be displayed stereoscopically. The method of building the 3D model library is described. The dentition models were reconstructed by the serial cross-sectional images acquired from CT, on which the expert drew the component parts of the dentures. In addition, the method of designing the knowledge library is described, and two samples of denture designing are listed in the end.更多还原
