PURPOSE Evaluation of the available research on PEEK materials to find that whether PEEK material has favorable properties and can enhance osseointegration, so that they can be utilize as implants material. MATERIALS AND METHODS An electronic and structured systematic search was undertaken in May 2018, without any restrictions of time in the Medline/Pubmed, Sci-hub, Ebscohost, Cochrane, and Web of Science databases. To identify other related references further hand search was done. Articles related to PEEK and their applications in implants were only included. Articles not available in abstract form and article other than English language were excluded. RESULTS Initially, the search resulted in 153 papers. Independent screenings of the abstracts were done by the reviewers to identify the articles related to the question in focus. Sixty-two studies were selected out of which 10 were further excluded due to not in English language. Two additional papers were obtained after hand searching, and finally 54 articles were included in the review. CONCLUSIONS Surface modification of PEEK seems to enhance the cell adhesion, proliferation, biocompability, and osteogenic properties of PEEK implant materials. PEEK had also influence the biofilm structure and reduces the chances of periimplant inflammations. Further research and more number of controlled clinical trials on PEEK implant is required in near future so that it can replace titanium in future.
