Pinos intrarradiculares: revisão de literatura e uma análise crítica das falhas

Abstract

The rehabilitation of endodontically treated teeth, especially those with extensive loss of coronal structure, often requires the use of intraradicular posts to provide retention and support for indirect restorations. Among the available systems, cast metal posts and fiberglass posts stand out and are widely discussed in the scientific literature. This study aimed to conduct a literature review on the main types of intraradicular posts used in clinical practice, evaluating their performance and the most common failure mechanisms. The analyzed studies indicate that failures related to cast metal posts are predominantly due to fractures, while fiberglass posts more frequently fail due to loss of adhesion and subsequent debonding. It is concluded that, although both systems have clinical indications, fiberglass posts tend to present a better restorative prognosis, since their failure modes are generally more favorable to the preservation and rehabilitation of the dental element .
