Monolithic zirconia crown with intracanal retention: A case report

Abstract

Intracanal retention determines the successful restoration after endodontic retreatment. Before inserting an intracanal retention, factors such as remaining amount of coronal tissue, root canal size and configuration, tooth position, functional requirements, and occlusion need to be analyzed. Fiber post is biocompatible, has good physical properties, and has the capacity of adhesive bonding to tooth tissue and core build up. This study aimed to determine the success of endodontic retreatment using prefabricated fiber post as an intracanal retention. A 31-year-old female patient came with a chief complaint of intense pain on right mandibular second premolar no. 45. In the first visit, radiograph of tooth no. 45 was taken, followed by caries removal and removal of screw post using ultrasonic tips with counterclockwise movement. In the second visit, endodontic retreatment was performed. Reduction of gutta-percha and cementing its prefabricated fiber post were carried out followed by composite core build-up until making temporary crowns using acrylic base resin. At the third visit, cementation for final restoration with a monolithic zirconia crown was performed. Endodontic retreatment is an alternative procedure for endodontics that fails even for teeth with post-intracanal therapy. Prefabricated fiber post as intracanal retention followed by a monolithic zirconia crown can be the best option so that the teeth can last as long as possible in the mouth.
