Types of Post and Core Systems

Since the advent of post and core systems, dentists have regularly accepted the traditional cast and post and core as choice of treatment modality to restore a badly broken root canal treated tooth. The important question being, if at all the cast, post is indicated in every case. Other concept being that a cast post compared to a prefabricated post improves the strength of a root canal treated tooth which has been weakened by decay or over preparation. Literature indicates the ultimate strength of the remaining tooth structure is defined by the bulk of the remaining dentin as it improves the fracture resistance of the teeth. However, a prefabricated post causes lesser tooth fracture when subjected to stress as compared to cast post system. This review aims to present the different post systems as an alternate to conventional cast post and their advantage and disadvantage.
