The purpose of this study is to review polyether ether ketone (PEEK), its properties, and its application in prosthodontics. Information about PEEK and its use in prosthodontics was searched for in Medline using PubMed, Science Direct, Wiley Online Library, and Google Scholar sources. For this review, 10 full-text articles were chosen and utilised. 140 articles matching the keywords PEEK, prosthodontics, and dentistry were located in the database. Organizing the information on PEEK polymer compatibility by mechanical, chemical, physical, and PEEK surface preparation. PEEK polymer is appropriate for prosthodontic application. There aren't enough claims about difficulties, the growth of biofilm on PEEK surfaces, or its resistance to compression, though. To learn the outcomes, more study should be conducted
