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.
