title: Restoring teeth with prefabricated fiber-reinforced resin posts.
abstract: The use of fiber-reinforced resin (FRR) posts to restore endodontically treated teeth has gained popularity as an alternative to cast or prefabricated metal posts. This may be due to the two important characteristics of fiber posts: I) their modulus of elasticity, which is similar to that of dentin, and 2) their ability to be adhesively cemented. The following article will discuss these characteristics, clinical indications for FRR posts, as well as increased fracture resistance, adhesion to root dentin, and guidelines for placement.
  
  
  OBJECTIVE
  This article reviews recent research on prefabricated fiber-reinforced resin (FRR) endodontic posts. Upon completing this article, the reader should: Understand clinical guidelines for the selection and cementation of FRR posts. Realize the importance of fracture resistance to the long-term performance of an endodontically treated tooth.
