可摘局部义齿计算机三维图形库的建立

Establishment of a computerized 3-D model library for removable partial dentures

目的建立可摘局部义齿组成部件三维图形库。方法建立牙颌计算机三维模型并以其为基础,采用“个别建模、组合模拟”的方式,运用3DStudioMax对可摘局部义齿各类部件单元在统一坐标下进行三维建模。结果完成义齿部件单元408个,构建可摘局部义齿计算机三维图形库。结论探索了一种创建三维义齿专家系统图形库的方法。

Objective To establish a computerized 3-D model library, including elements for removable partial dentures. Methods On the basis of having established a computerized 3-D model of defect dentition, 3D Studio Max was used to reconstruct a series of 3-D models of elements for removable partial dentures under the same coordinating system. Results A 3-D model library was established, including 408 elements for removable partial dentures. Conclusion A new method was provided to establish a model library for the 3-D denture expert system, which would also be an important basis for the further exploration of a 3-D computer aided expert system for designing removable partial dentales.
