Development of Crown Production System by Virtual Articulator and NC Machine Tool

Abstract

This paper introduces a dental crown production system. The crown designed in this system not only had nointerference at intercuspal position but also given functional occlusal surfaces. The functional occlusal surface was createdwith virtual articulator which reproduces the movement of subject's mandible on a computer system. Finally, validity of theprocesses in this crown production system, errors which were caused in each process and the necessity of dental CAE (Computer-Aided Engineering) system were discussed.
