Lithium silicate endocrown fabricated with a CAD-CAM system: A functional and esthetic protocol.

An endocrown restoration is an alternative approach to complete crowns with intraradicular cores or dowels for the restoration of endodontically treated teeth. Endocrowns conserve tooth structure and require fewer dental visits. This approach has been widely used, and various materials and techniques have been reported. Computer-aided design and computer-aided manufacturing (CAD-CAM) systems can generate and store libraries of teeth with various anatomies in their database, and diagnostic tooth waxing may not be required. However, occlusal adjustments after the cementation of indirect restorations are often frustrating. Thus, a rapid and efficient way of addressing this challenge is necessary. This clinical report presents a protocol for the fabrication and delivery of an endocrown by using the biogeneric design mode with lithium silicate-based ceramic adjusted before its complete sintering.
