Abstract:

Nowadays, post-and-core systems have become an important technology of prosthodontics. Clinically, post -and -core crowns are used to restore teeth which have received perfect root canal treatment, but cannot achieve good retention. In a few decades, metal posts have held an important place in clinical application. But the elastic modulus of metal posts is higher than that of dentin, contributing to severe root fractures. Since the elastic modulus is similar to the dentin, fiber posts can reduce root fractures. They can also be easily taken out after fractures. Owing to these advantages, fiber posts have been accepted by dentists since 90 years of 20 century. This review aims to introduce advanced studies of prefabricated fiber posts in terms of classification, properties and clinical application.

Key words: fiber post, prefabricated fiber post, post and core, fiber-reinforced composite post
