This paper demonstrates the successful application of a novel approach to the computer aided design (CAD) of removable partial denture (RPD) framework. Firstly, we get the data of the partially edentulous cast, a mandibular Kennedy Class II, through a 3D-optical grating measuring system after corresponding pretreatment. Then, the reverse engineering software and 3D CAD software was used to design basis, big conjunction, clasp, small conjunction of the RPD framework. Finally 3D surface model of the RPD framework was created in preparation for direct manufacture using rapid prototyping (RP) methods and foundry. The result indicated that the RPD framework was fabricated successfully and the resulting frameworks provided a satisfactory fit.
本文展示了一种新颖方法在可摘局部义齿（RPD）支架计算机辅助设计（CAD）中的成功应用。首先，在进行相应预处理后，我们通过三维光学光栅测量系统获取了下颌Kennedy II类牙列缺损模型的数据。然后，使用逆向工程软件和三维CAD软件设计RPD支架的基托、大连接体、卡环、小连接体。最后创建RPD支架的三维表面模型，为使用快速成型（RP）方法和铸造进行直接制造做准备。结果表明，RPD支架成功制作完成，所得支架贴合度良好。
