ABSTRACT
BACKGROUND: The loss of tooth structure in endodontically treated teeth compromises their structural integrity and increases their vulnerability to fractures. To strengthen these teeth, post and core systems must be used. Among post materials, glass fiber has become more and more common because of it advantageous mechanical and aesthetic qualities. However, the effectiveness of customized glass fiber posts in enhancing fracture resistance compared to prefabricated posts remains a subject of ongoing debate.
OBJECTIVE: This systematic review primarily focuses on the fracture resistance of endodontically treated teeth reinforced with customized glass fiber posts. It aims to assess how well they function in terms of resilience, flexibility, and failure patterns in comparison to prefabricated fiber posts and other post materials.
METHODS: To locate relevant studies published up to 2025, a comprehensive literature search will be conducted through various materials available electronically on websites such as Google Scholar, Web of Science, PubMed, Semantic Scholar, and Scopus. The selection criteria will include randomized controlled clinical trials that evaluate fracture resistance of customized glass fiber posts in teeth that have had endodontic treatment. The research will be screened using predetermined standards for inclusion and exclusion. Quality assessment and collection of data will be performed strictly, in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. To examine the results quantitatively, a meta-analysis will be conducted, if at all possible, with a random effects model for heterogeneity. Statistical methods will be used for evaluating the effectiveness of custom glass fiber posts, alternative post materials, and prefabricated posts.
RESULTS: By comparing the mean differences in fracture resistance of teeth treated endodontically using various post systems, the effectiveness of customized glass fiber posts will be assessed. Other aspects to be examined include general biomechanical performance, failure mechanisms, and stress distribution. This study will use a random effects model to estimate the combined effect size measurements and the corresponding 95% CIs. We anticipate that the data synthesis will be conducted between February and March 2026 for this systematic review and will be finished by April or July 2026.
CONCLUSIONS: Customized glass fiber posts may show promise in strengthening teeth that have undergone endodontic treatment by lowering the risk of failure and increasing fracture resistance. Even if there is current evidence that they are more effective than prefabricated posts, we need to synthesize the quality of the evidence. Therefore, this review aims to evaluate whether customized glass fiber posts effectively enhance fracture resistance in endodontically treated teeth.
