There are 20% of articles related to the properties of PEEK, which revealed the superior mechanical properties over the existing metals used in dentistry. Therefore, keeping all these in mind, in this review, we aimed to focus exclusively on the mechanical properties, advantages, modifications of the PEEK material and different uses of PEEK in various specialties of dentistry. PEEK is the latest inventory of dentistry and is claimed to have better properties in parallel with existing materials. The dental profession always thrives for better materials which can fulfill the pitfalls of the existing materials. The existing materials despite having superior qualities have certain drawbacks like attrition of the natural teeth and bulkiness which may lead to a compromise in the retention of the prosthesis as well as patient satisfaction. This can provoke a dark shimmer of the peri-implant soft tissue in cases of thin biotype mucosa and mucosa recession around the implant. Titanium can cause aesthetic problems due to its lack of light transmission. Few studies also claimed that titanium is prone to hypersensitivity reactions. Titanium implants are also known to cause image distortions in MRI scans. This phenomenon is referred to as stress shielding, and it may be one of the important causes of long term failure of dental implants. Due to the gradient difference in the elastic modulus of a titanium implant to its surrounding bone, it may cause stress in the implant-bone interface during load transfer resulting in peri-implant bone loss. The elastic modulus of titanium and zirconia are 110 and 210 GPa respectively which is 5-14 times greater than that of compact bone having 15 GPa. ![]() Studies have already proven that these materials are biocompatible, but even these have some short comes, one of them being the elastic modulus. ![]() Titanium and its alloys and Zirconium are predominant in the field of implant materials in today’s dental practice. The long term success of dental implant depends mainly on minimizing the amount of marginal bone loss on functional loading. The literature showed that the PEEK material has superior mechanical properties with different uses in various specialties of dentistry. PEEK has been explained for a number of applications in dental practice. Finally, 85 articles were found to be relevant. 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. An electronic literature search was conducted through Medline via PubMed, Wiley Online library, EBSCOhost, Science Direct, as well as the Google Scholar between January 2010 and March 2018 using the keywords: PEEK, modified PEEK, PEEK and Dental, advantages of PEEK, applications of PEEK in dentistry and PEEK Implants. 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 space for the metal-free restorations in today’s dental practice. ![]() This study is aimed to review the applications of Polyether Ether Ketone (PEEK) in dentistry.
