Abstract

It is stated that the search for new materials in today's dentistry continues in order to meet aesthetic and functional expectations. As a result of these searches, materials such as PEEK (polyetheretherketone) , PEKK(polyetherketoneketone) and BioHPP(bio high performance polymer) have become widely preferred in dentistry. PEEK is a thermoplastic polymer. It offers features such as durable structure, tissue compatibility and lightness. Therefore, it is attracting interest as a metal alternative and is considered as a promising material in dental treatment applications. In addition, PEEK's biocompatibility properties enable it to be used in the biomedical field. PEEK is a material that resembles natural tooth color and has been used as a biomaterial in orthopedics for many years. PEKK is a newly developing polymeric material. PEKK biomaterials are elastic with excellent shock absorption and fracture resistance, demonstrating ultra-high performance compared to other thermoplastic composites, offering exceptional mechanical strength, chemical resistance, and high thermal stability. BioHPP is a PEEK-based bio high-performance polymer that has been shown as a dental substrate material. It can be used in different areas of dentistry due to its advantages such as excellent physical and aesthetic properties, low weight and biocompatibility. "PEEK and PEKK, which are polymer materials, can be successful alternatives aesthetically, mechanically, and biologically to dental implants, crowns, bridges, and removable denture framework materials in dentistry." However, it is emphasized that they should be used with caution due to insufficient clinical studies. Especially the fatigue stress and long-term performance of PEEK require further research. Therefore, studies based on more comprehensive and reliable clinical data on the use of these materials are needed.
