Abstract

Objective: The aim of the study is to assess the fracture resistance of anterior teeth restored with PEEK custom made post and core versus traditional post and core. Materials and Methods: In this in-vitro investigation, 20 sound upper central incisor teeth extracted due to periodontal disease were endodontically treated and randomly divided into two groups (n = 10), group I restored with
prefabricated fiberglass post and composite core, and group II restored with PEEK post and core. Zirconia crowns have been used to restore teeth. The Instron Universal Testing Machine was used to perform the fracture-resistant test. The Kruskal Wallis test was utilized to assess the fracture resistance data, and the t-test was used for comparison. Results: It was found that the teeth restored 
by fiber posts had considerably higher fracture resistance and are statistically significant different from teeth restored by PEEK posts. Conclusion: Fiber posts strengthen teeth than PEEK posts and are more suited for high-stress dental restorations. Although PEEK material has potential, further improvements are needed to enhance its mechanical properties. Further research is needed to assess its long-term viability.
