The restorative treatment of non-vital teeth is a common problem for dentists. The most difficult task is the rehabilitation of highly damaged endodontically treated teeth (ETT), which has a higher probability of failure than viable teeth. Although the traditional crown supported by radicular metal posts is still extensively used in dentistry, it has been heavily criticized for its invasiveness. There are currently new materials and treatment possibilities based solely on adhesion. The endocrown is advised for the repair of severely damaged molars, which necessitates the use of particular restoration techniques to meet biomechanical criteria. They make it possible to undertake a more conservative, quicker, and less expensive dental procedure. It is recommended when the pulp chamber provides suitable conditions for retention. The coronal portion of endocrown is merged into the apical projection, which occupies the pulp chamber space and possibly the root canal openings. It is infrequently used, yet it deserves to be known and used more widely. With the introduction of new ceramics and adhesives, this endocrown may be viewed as a viable alternative to traditional crown-root anchored restorations in restoring ETT molar teeth. The lecture will discuss its preparation, indications, contraindications, advantages, materials used for its construction, and clinical cases of endocrown will be shown.
