In this study, a dental CAD/CAM system using titanium in the dental clinic was investigated. This system consisted of a CAD to perform prostheses visualizing and CAM to perform the procedure. There are many reports on this system and studies on the CAD system. However, the fitness of prostheses in the dental clinic is important, and the accuracy of manufacturing by CAM must be investigated in detail.<BR>High bio-compatibility titanium was very useful as the material for prostheses. Due to its characteristics, the casting method was difficult, and the CAD/CAM system using the cutting method as the manufacturing method was considered to be effective. In this study special attention was paid to the CAM system, and influence of milling methods on titanium surface was investigated. The results were as follows:<BR>1. The difference in the milling method affected the external shape of the product.<BR>2. The relationship of the cutting tool and shape of the titanium product and the difference in condition of milling affected the surface texture.<BR>3. The configuration milling method necessary for high accuracy of manufacturing of the periphery was radial milling.
