A CAD/CAM system for the production of metal copings for porcelain-fused-to-metal restorations

J Prosthet Dent. 1995 May;73(5):457-63. doi: 10.1016/s0022-3913(05)80075-7.

Abstract

A computer-aided design and manufacture system for the production of metal copings for porcelain-fused-to-metal restorations is described and evaluated. The three stages of production: digitizing, mathematical processing, and milling are described, with emphasis on the system's ability to produce metal copings for both single-unit and multiple-unit restorations. Evaluation of the marginal fit of the produced copings demonstrates the potential for clinically acceptable results.
