[Design of geometric models of the removable partial denture framework].
Shanghai Kou Qiang Yi Xue. 2006 Apr; 15(2):213-7.SK

Abstract

PURPOSE

The aim of this study was to introduce a method on computer aided design (CAD) of removable partial denture(RPD) framework based on domestic CAD/CAM software system, which contributes to the further research to develop the domestic software system applied in restorative dentistry.

METHODS

Point cloud data of a partially edentulous cast, a mandibular Kennedy Class II modification 2 arch, was captured by an optical scanning system with projective grating and high-resolution digital camera. Using domestic CAD/CAM software system, the above point cloud data was reduced, digital surveying line and inserting path were determined. In terms of the principle of clinical design, the tissue surfaces and polishing surfaces of every component of RPD were built such as clasp, rest, lingual bar, and mesh construction, et al. As well as the characteristic structures of the framework, including the half-pear shaped cross section of lingual bar, the internal and external finish lines, the tissue stop at the tissue surface of mesh construction and so on, were fabricated on the base of reduced data model. 3-D surface model of the RPD framework was created.

RESULTS

Geometric model of the RPD framework was fabricated successfully, which took on good fitting, high visibility and editing conveniently. And the data converted to STL file format that could be read by any other CAD/CAM software system and was in preparation for subsequent computer aided manufacture (CAM) of RPD framework.

CONCLUSIONS

It is suggested that this method based on domestic software in CAD of RPD framework be feasible.
