According to a recent study published in the Journal of medicine and life, Polyether Ether Ketone (PEEK) material has superior mechanical properties with different uses in various specialities of dentistry.

This study is aimed to review the applications of Polyether Ether Ketone (PEEK) in dentistry. The increased demand for aesthetics, legislation in some developed countries, few drawbacks with existing materials and clinicians shifting their paradigms towards metal-free restorations led to space for the metal-free restorations in today's dental practice.

An electronic literature search was conducted through Medline via PubMed, Wiley Online Library, EBSCOhost, Science Direct, as well as the Google Scholar between January 20 10 and March 2018 using the keywords: Polyether Ether Ketone (PEEK), modified Polyether Ether Ketone (PEEK), Polyether Ether Ketone (PEEK) and Dental, advantages of Polyether Ether Ketone (PEEK), applications of Polyether Ether Ketone (PEEK) in dentistry and Polyether Ether Ketone (PEEK) Implants. A total of 103 articles were found in the literature search, and out of these, 18 were not related to our study and hence were excluded. Finally, 85 articles were found to be relevant. Polyether Ether Ketone (PEEK) has been explained for several applications in dental practice.
Thus, the literature showed that the Polyether Ether Ketone (PEEK) material has superior mechanical properties with different uses in various specialities of dentistry.
