Purpose: The Dental Cadim® (dental CAD/CAM system) measures the shape of the wax pattern by contact process, and milling of the metal block. The purpose of this study was to fabricate a metal coping from a titanium block by the Dental Cadim®, and examine its processing precision.<BR>Methods: The sample of the metal coping was fabricated by this Dental Cadim (R) system, and its processing precision was investigated. Next, only the process of milling was repeated, and the error in the milling was examined. The processing precision was evaluated by measuring the amount of gaps of the metal coping and the die.<BR>Results: The error of A-type (acute angle type) was larger than the error of R-type (round type). The amount of gaps of the metal coping and the die was about 0.100mm, on average. The error in the milling wassmall.<BR>Conclusions: 1. A metal coping with a post could be made adequately by this dental CAD/CAM system. 2. The shape of the boundary between the coping and post influences the processing precision in this system. 3. The error inthe measurement process was greater than the error in the milling process, and the error in the measurement process influences the processing precision.
