Introduction: Endocrown is a one-piece restoration that takes strength from the pulp chamber of root canal treated tooth. The basic concept behind the endocrown is that it develops a bonded all-ceramic restoration that takes its strength partially from the pulp chamber and is metal-free. For a very grossly decayed tooth, using a post and taking strength from the canals that are already weakened after endodontic treatment leads to decreased strength of the tooth, and hence endocrowns are a good alternative. 

Aim of Work: This review article talks about endocrowns and their advantages over the conventional full-coverage crowns.

Methodology: This review is a comprehensive research of PUBMED from 1999 - 2018.

Conclusion: Endocrowns are an easier and conservative alternate for full coverage crowns. Glass ceramic restoration when used with CAD-CAM make a monolithic restoration that has more strength, and because of the butt joint there is better distribution of forces along the joint and the axial walls and hence reduces the force applied on the pulpal floor. The endocrowns are a perfect example of bio integration and are a good alternative to restore grossly decayed posterior teeth.
