APPLICATION OF PEEK: A FUTURE REVOLUTION IN PROSTHODONTICS

Abstract

The aim of this study is to review polyether ether ketone (PEEK), its characteristics and use in prosthodontics. Polyetheretherketone (PEEK) is one of the most used semi-crystalline thermoplastic polymers in aeronautics and aerospace. This new material matches the technological advancements and patient's desires for a natural and aesthetic look, thanks to its strength, superior biocompatibility, low plaque affinity and aesthetics characteristics close to the desired natural dental structure. PEEK has good mechanical and electrical properties such as resistance to high temperature and resistance to hydrolysis. Satisfactory findings have also been observed when used in knee, hip, spine and other implants. PEEK polymer is suitable to use in prosthodontics. PEEK can fulfil the long-term demand of an ideal multipurpose material for biomedical applications. However, there are not enough statements about complications, biofilm formation on PEEK surface and its resistance to compression. More research should be done to find out the results.
