Introduction: Endocrown is an alternative restorative option for endodontically treated teeth with significant loss of coronal structure. It is a 1-piece restoration that uses the pulp chamber for retention by means of adhesive cementation. This approach is gaining popularity and various materials have been reported.

Case Description: A 72 years old Chinese female presented with a heavily restored and endodontically treated maxillary right first molar. The tooth was given a guarded prognosis due to the loss of substantial tooth structure. The decision was made for an endocrown as opposed to the conventional method of crown lengthening surgery followed by a cast-post-core and crown. Crown lengthening was contraindicated given the short roots and close proximity of the root furcation to the crestal bone. The endocrown was fabricated using monolithic zirconia and cemented with resin cement using the adhesive technique. There were no complications reported during the review appointments.

Discussion: Endocrown is a single monoblock restoration consisting of a intraradicular post, core and crown. It allows for the conservation of tooth structure and also a reduced clinical time. Retention of the crown is obtained via macroretention by engaging the internal wall of the pulp chamber and the crown preparation margins while micro-retention is achieved with the use of adhesive cements.

Conclusion: The patient was satisfied with the treatment outcome. At one-year follow-up, the endocrown is still functional and in good condition. Endocrowns may be considered as a feasible treatment option for the restoration of endodontically treated teeth with compromised tooth structure. However, stringent case selection is necessary.
