Endocrowns: when less is more

Abstract

The need for replacement of crown in a grossly decayed endodontically treated tooth is a challenging task for most practitioners. Post and cores are the most widely recommended treatment option for such cases associated with extensive loss of tooth structure, which is eventually followed by fabrication of full coverage crowns supported by metal or adhesively bonded cores. In the past, it was believed that this procedure would help in reinforcing the remaining tooth structure.However, it is now evident that a post would only serve as a mechanical retainer for the core and does not strengthen the compromised tooth.Ideally, a post-endodontic restoration should protect and preserve the existing tooth structure, while restoring esthetics, form, and function. The aim is to achieve a minimally invasive preparation with maximum tissue conservation for restoring endodontically treated teeth. With the advent of adhesive dentistry it is now possible to limit the amount of tooth preparation required. The endocrown was first proposed by Bindl and Mormann, who suggested that it would produce a monblock effect by utilising the available surface in the pulp chamber and obtain retention through adhesive bonding.This case report highlights the successful post endodontic management of an extensively decayed molar using a ceramic endocrown
