Peek-prospective prosthesis material: A narrative review

Abstract

Polyetheretherketone (PEEK) is a thermoplastic polymer that has many potential uses in dentistry. This review aims to summarize the reported applications of PEEK as a prosthetic material, the research conducted in regard to its properties concerning prosthetic applications and the future prospects of PEEK as a provisional or permanent prosthetic material. Original scientific articles published in Medline-Pubmed database were electronically searched. Articles published in English were identified, regardless of the year of publication, using a variety of keywords in combination. The studies relevant to our review were critically analysed and summarized. As a result it was found that due to the favorable mechanical and physical properties of PEEK, it can serve as an appropriate alternative material for various uses in dentistry. However, for further dental applications extensive research and clinical trials are required.
