Literature review on zirconia post system

Cast metal post and core systems have been reliably used for decades due to their excellent physical properties. However, the increasing demand for aesthetically pleasing and biocompatible restorations has spurred the development of tooth-colored post and core systems. Among these, zirconia post systems have gained popularity, offering a solution that combines strength with enhanced esthetics. The translucency of zirconia allows for seamless integration with all-ceramic crowns, maintaining a natural appearance and meeting patient expectations for visually appealing restorations. In light of the growing interest in zirconia ceramic post systems, numerous in vitro studies have been conducted over the past 15 years to evaluate their performance. These studies have examined critical aspects such as retention, fracture resistance, and aesthetic advantages. Zirconia posts are celebrated for their ability to improve esthetics while providing sufficient strength and long-term durability. Nevertheless, zirconia posts are not without limitations. Issues like achieving proper cementation and optimal adhesion remain active areas of research and clinical focus. This review article aims to consolidate existing data on zirconia posts, highlighting their retention, fracture resistance, aesthetic benefits, challenges, and cementation techniques to aid clinicians in their effective application.
