Outline of Final Research Achievements

The purpose of this study was to reproduce a functional configuration/occlusion to duplicate dentures accurately. We duplicated full dentures, which were in working use, through CAD/CAM technology. The dentures were scanned via a 3D-surface scanner. The scanned data was then divided into the denture base and the artificial teeth. From the digital data, the plaster and wax patterns were fabricated via 3D printers. Finally, based on these patterns, the acrylic resin denture base and the ceramic artificial teeth　were fabricated. Through our method, the functional configuration/occlusion could be reproduced accurately to duplicate dentures.
