Rehabilitation of endodontically treated molar stilla challenge. After endodontic management of extensively carious molars, theyhave decreased mechanical characteristics. They became fragile and that is in relation with the removal of pulp and adjacent dentin tissues. Endocrown which is a single partial restoration could be measured as a good alternative for restoring molars having large coronal destruction and presenting endodontic treatment complications. We discuss the indication and use of endocrown to substitute single crowns with intraradicular retention and to present a clinical case report of an endocrown-type restoration, made-up from lithium disilicate ceramic (IPS e.Max CAD) in a mandibular first molar with widespread coronal destruction.
