Recent Advances in Post Systems -a Review

Abstract

Preservation of natural tooth in dental arch is ultimate objective of dental treatment. After endodontic treatment, tooth becomes brittle and prone to fracture which results in reduction of strength of crown causing fracture of cusp or sometimes weakness of the roots. In order to strengthen crown some anchorage within teeth has to be made and that anchorage and support is gained by rigid structure which is known as post. This article focuses on recent advances in post systems and their application, merits and demerits in endodontics.
