抄録

The introduction of CAD/CAM technology was tried for the improvement of the quality of prosthetic restoration and of efficiency of the dental technician's work.<BR>In this study, CAD was examined as a method for prosthetic restoration, and as a result, the conclusions were as follows:<BR>1. In order to design a tooth crown form by computer, it was necessary to freely treat a tooth crown form that has a complex three-dimensional freedom curved surface.<BR>2. For this purpose, voxel model, spline model, and rational bezier model were examined. The data of the voxel model was easy to treat but difficult to transform effectively, and the problem there of was the quantity of data increased when the surface was smoother. In case of the rational bezier model, it was possible to transform the model according to expectation.<BR>3. As one method of transformation of the tooth crown form using rational bezier surface, it was advantageous to transform without changing the control points by changing the weight-parameters.<BR>4. The CAD system for prosthetic restoration was based on MCCM-solid-model using rational bezier surface, and it was found to be possible to make the prosthetic restoration in this CAD system like those made in dental technical work.
