Abstract
This article demonstrates a case that successfully placed a retro-fitted crown restoration under an existing denture by employing the characteristics of digital technology. Scanned data of the arch that involves edentulous area, and ofthe old denture itselfwere obtained and superimposed on each other. A virtual crown was modeled in computer-aided design software with marginally larger than the ideal size. The old denture was regarded as an adjacent tooth in the setting menu so that the portion ofthe virtual crown that extends over to the old denture could be automatically deleted by selecting the “Cut intersections” option. This retro-fitted crown was milled with a polymethylmethacrylate disc after a minor adjustment ofits contour. The crown and the old denture were placed in the patient’s mouth, and resulted in favorable esthetic outcome and occlusion, showing proper relationship with the old denture.
