Endodontically treated teeth show greater risk of failure than their vital counterparts. In the case of insufficient tooth structure those teeth often need a Post & Core as a foundation for the final restoration. A Post & Core protects the remaining tooth structure and allows the restoration of function1. a new method of fabricating custom made Post & Core is the use of monoblock zirconia and all ceramic CAD/CAM technology (computer-aided design/computer-aided manufacturing).

Endodontically treated teeth show greater risk of failure than their vital counterparts. In the case of insufficient tooth structure those teeth often need a Post & Core as a foundation for the final restoration. A Post & Core protects the remaining tooth structure and allows the restoration of function1. a new method of fabricating custom made Post & Core is the use of monoblock zirconia and all ceramic CAD/CAM technology (computer-aided design/computer-aided manufacturing). The Post & Core restoration is generated by means of a direct optical impression of the post space or an indirect impression of a resin pattern or polyvinylsiloxane impression of the post space4. The purpose of this study was to evaluate the use of CAD/CAM technology as a method to fabricate a single-unit, all-ceramic Post & Core restoration.
