An Approach to the Dental CAD/CAM(Part 3) : The CAD Data Base

Abstract

Studies were undertaken to apply the CAD/CAM system to Dentistry and to make prosthetic appliances automatically.The dental CAD data base was made by measuring the typical tooth models.The measurement was done by a trial 3D point digitizer.To obtain good fitness to the original figure with a small amount of surface point data, 3D spline interpolation was added.Using the convenient CAD/CAM data system, each tooth was measured at the position of the arch formation.To monitor the occlusion, the 3D coordinates and points situations enable to compile some new data, number of data, and the conditions of the interpolation, are considered.
