Fabricating a post-and-core and a crown restoration for an endodontically treated tooth with extensive loss of tooth structure is complicated, difficult, and time consuming. This article describes 2 techniques for fabricating an anatomically correct ceramic core with fewer defects and a crown restoration with appropriate thickness by using intraoral digital scanners and computer-aided design and computer-aided manufacturing and rapid prototyping technologies.

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.
