Endodontically treated teeth with extensive loss of tooth structure is a challenging task for a dentist to restore. Restoration via direct or indirect technique increases the mechanical strength as well as provides a stabilizing effect on the remaining tooth structure. The number of remaining walls, occlusal height, as well as total remaining girth of the walls available have been used as a guide to choose the treatment option after root canal treatment. Extensive loss of tooth structure warrants a full-coverage restoration which can be given over a core supported by a post. Endocrown is a one piece restoration, usually indicated in cases with decreased crown height. This treatment option maintains the biological health of soft tissue and prevents interferences with periodontal tissues as due to the presence of supragingival position of the margins. Endocrown uses the surface area presented by the internal walls of the pulp chamber to obtain micromechanical bonding to the tooth surface. In this case study, a badly mutilated mandibular molar was rehabilitated using a monolithic ceramic restoration. Endocrown is minimally invasive and a suitable alternative to post and core wherever indicated.
