The highest mean shear bond strengths were observed for acid-etched PEEK surfaces, followed by laser-irradiated, airborne particle abraded, and silicoated PEEK surfaces providing similar mean shear bond strengths. Since shear bond strengths higher than 10 MPa are considered acceptable, acid etching, laser irradiation, and airborne particle abrasion of PEEK surfaces may be considered viable surface treatment modalities for the PEEK material tested.

Polyether Ether Ketone (PEEK), is a semi-crystalline high-temperature thermoplastic polymer in polyaryl ether ketone family. PEEK of high mechanic and physical features, thermal and dimensional stability, is one of rare polymers seen as an alternative to metal materials in many industrial fields. With its features like, high-corrosion and chemical resistance and compatible biomechanic features, long-life and biocompatibility, PEEK began to be used especially in medicine as high-performance thermoplastic material alternative to metal-composite implants in orthopedics in the late 1990's. PEEK is used as an implant material, because of its elasticity module. That's why it is used as a prosthetic material in dentistry. In this study, the structure, general features and the use of PEEK material are explained.
