The preparation for endocrowns is rational and simple and can be performed quickly. Root canals are not involved in the process, and the procedure is less traumatic than alternatives. The supragingival position of the cervical margin preserves the marginal periodontium, facilitates impression taking and maintains the solid substance of the remaining tooth. The endocrown fits perfectly with the concept of bio integration and belongs among the restorative options for posterior endodontically treated and badly damaged molars. Endocrowns have been used as an alternative to the conventional post-core and fixed partial dentures in the restoration of ETT with extensive coronal tissue loss. Compared to traditional methods, better aesthetics and mechanical performance, low cost and short clinical times are the advantages of endocrowns. The endocrown represents a very hopeful treatment alternative for endodontically treated teeth, it allows maintaining of tooth structure, it is compatible with goal minimally invasive dentistry, and it is adequate for the concept of bio-integration. It is a conservative approach for mechanical and aesthetic restoration of non-vital posterior teeth.
