Efectividad de postes de fibra de vidrio en dientes tratados endodónticamente. Revisión bibliográfica

Abstract

After having performed an endodontic treatment, the restoration of the treated tooth is necessary. Currently, dentists have several options of techniques and materials to select the best alternative that makes it possible to restore aesthetics and function to the tooth when it has lost much of the integrity of the crown. One of them is the use of fiberglass poles. The objective of this research was to determine the effectiveness of the use of fiberglass posts in endodontically treated teeth. The study had a documentary design and was a bibliographic review. Eight articles were included: three clinical trials, three systematic reviews with meta-analysis, one systematic review without meta-analysis, and one retrospective study. Intraradicular posts are indicated when the teeth have only one wall and/or less than one third of the remaining height of the clinical crown. When comparing the use of fiberglass post retained restorations with direct non post retention restorations, when a fiberglass post was used the survival rate was 94% and when no post was used the survival rate was of 76.3%. Cast posts usually have a higher failure rate due to the high risk of root fracture.
