Polyetheretherketone: Properties, Modifications and Applications in General Dentistry

Abstract

Abstract The commercialisation of polyetheretherketone (PEEK) of polyaryletherketone family paved for the new development in the medical field, especially in dentistry. The high performance and better bioavailability, biocompatibility and strength all together made this material a replacement for laboratory technicians to switch from conventional metallic and zirconium alloys to PEEK. The objective is to know the general characteristics, mechanical and chemical properties and various uses of PEEK in dentistry and the use of PEEK in implant prosthodontics. Various modifications of PEEK like Carbon fiber reinforced (CFR-PEEK) and Glass fiber reinforced (GFR-PEEK) were discovered to replace unreinforced PEEK due to its better physical and mechanical properties. The various applications of PEEK are also a main objective. PEEK has replaced titanium in implant dentistry because of its better tensile strength and its elastic modulus which is close to the dentin. The advantages and disadvantages of PEEK in dental implant prosthesis are also considered.
