Mechanical properties of PEEK as an orthodontic fixed retainer after adding of reinforcing materials(A systematic review )

Abstract

The aim of this systematic investigation was to provide a thorough analysis  of the ways in which  reinforcements effect on the mechanical properties  of dental PEEK materials. A digital systematic review was undertaken in multiple databanks: searches were made in Science Direct, PubMed, Web of Science, and Google Scholar, combined with a manual search of scientific literature.  Papers published between 2005 and 2024 were collected and reviewed, and relevant publications were selected to be included in this review.  Studies established the influence of supplementary elements on the mechanical characteristics of polyetheretherketone. Conclusion:  Incorporation of inorganic compounds into the PEEK matrix may enhanced its  mechanical properties, thereby improving its suitability for high-load dental applications, particularly in the fabrication of fixed orthodontic retainers
