Simple Duplication Technique of Complete Denture Using an Intraoral Scanner

This is the authors' abstract. We don't add key points for this paper.

Various techniques have been applied to the fabrication of duplicate dentures. In this new method, after scanning the cameo and intaglio surfaces of the complete denture using an intraoral scanner, the two images were superimposed on the interocclusal image. The linear gap between cameo and intaglio surfaces was filled using free downloadable CAD software. The superimposed image was subsequently used as data for fabricating the duplicate complete denture with a 3D printer. Using the intraoral scanner, duplication of complete dentures could be performed without needing any complicated processes, laboratory scanners, or advanced CAD software.
