Abstract:

Endocrown is a new restorative option which uses pulpal chamber for retention. It consists of a circular butt-joint margin and a central retention cavity inside the pulp chamber. The retention principle of Endocrown includes the retention form of pulp chamber and adhesive retention. The foundation of this technique is to use the surface available in the pulpal chamber to assume the stability and retention of the restoration through adhesive procedures. Guidelines for the preparation are dictated by the amount of remaining coronal substance. It is indicated to restore endodontically treated teeth with large area defect, especially for the short clinical crowns which could not be restored by post-and-core crowns. This technique represents a promising and conservative alternative to full crowns for the treatment of posterior nonvital teeth that require long-term protection and stability. In this paper, the advance of basic research and clinical application of Endocrown were reviewed.
