MIRROR-IMAGE ANTERIOR CROWN FABRICATION WITH COMPUTER-AIDED DESIGN AND RAPID PROTOTYPING TECHNOLOGY: A CLINICAL REPORT

This clinical report describes the fabrication of a maxillary central incisor single crown with rapid prototyping (RP) technology. A patient with a recently replaced metal ceramic crown had discomfort due to the nonanatomic lingual contour of the crown. With computer-aided design (CAD) software and rapid prototyping (RP) technology, the shape of the contralateral central incisor was duplicated and reproduced to make a mirror-image for a new crown. The prosthodontic planning and treatment approach are discussed. (J Prosthet Dent 2013;109:75-78)
