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 measuring machine (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 seting eight functional 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 managing model. 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) A CACDD 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.
