title: [Development and applications of a computer aided complete denture design system].
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.
  
  
  CONCLUSIONS
  This system lay down the foundation for setting up the computer aided complete denture design/manufacturing system.
