Indicaciones y recomendaciones en postes anatomicos en dientes tratados endodónticamente. Revisión de literatura.

Abstract

Background: Endodontically treated teeth with less than 50% of remaining structure require an intrarradicular post that provides greater stability to the tooth. However, prefabricated posts do not conform to the shape and anatomy of the root canal, instead, it leaves space between the post-dentin interface. On the other hand, due that anatomical posts reproduce the shape of the canal, it presents better mechanical and physical properties favorable for the tooth to be restored. Objectives: to evaluate and compare all the techniques, indications, and recommendations of the anatomical post. Materials and methods: a search of scientific articles published in the PubMed, Scopus and Dimensions AI databases was carried out using the keywords fiber post, post and core technique, CAD-CAM, cast post and composite. The articles were filtered using Mendeley and Rayyan software, and then filtered by full text according to the selection criteria. The results were tabulated in an Excel matrix. Results: a total of 5,578 articles were found, and after filtering, 43 articles were finally included. According to what was found, anatomical fiberglass posts using composite resin using direct technique have better physical and mechanical properties that ensure the survival of the post up to 7.2 years. Conclusion: anatomical fiberglass posts in composite resin represent a good treatment to perform for the restoration of teeth with dental remnants less than 50%, with favorable, aesthetic and precise results.
