Accelerated techniques for a post and core and a crown restoration with intraoral digital scanners and CAD/CAM and rapid prototyping.

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.
