RUIZ-MATOREL, Mónica et al. Fracture Resistance of fiberglass post vs cast post in anterior teeth. Systematic review. CES odontol. [online]. 2016, vol.29, n.1, pp.45-56. ISSN 0120-971X.

Anterior teeth with endodontic treatment and loss of tooth structure are usually restored with glass fiber posts or cast cores, which are susceptible to present failures that may potentially cause tooth loss because they are not able to be restored again. It is proposed here to identify which of the two types of posts: prefabricated fiberglass or cast posts, is more resistant to fracture due to biomechanical forces of compression that occur in the anterior teeth restored with crowns respect to fracture post , root or eviction of this. A systematic review of the literature was conducted with information gathered from the databases of search engines: PubMed, Scielo, Lilacs and Science Direct. Ninety three articles on the topic were screened according to the selection criteria. Four cumplied with this procedure and found that fracture resistance tends to be grater in teeth restored with cast posts, but when a tracture accors is untaorubale for a restorative retreat. In the case of fiberglass posts and greater remaining height structure better fracture resistance is presented, and they present a pattern usually more favorable for retreatment in case of fracture.
