Abstract:

With the ever-increasing interest in aesthetic restorations in today's dentistry, metal-free restorations similar natural tooth structure, biocompatible, with good mechanical and physical properties are more frequently preferred. Polyetheretherketone (PEEK), which is one of these materials, has a thermoplastic polymer structure and its use in dentistry has started to become widespread. PEEK is a semi-crystalline thermoplastic homopolymer with a two-phase linear chain structure consisting of aromatic ring and amorphous-crystalline phase connected to each other by ketone and ether functional groups, with a density of 1.3-1.5 g/cm3. PEEK material has properties such as being biocompatible, elastic modulus closer to bone, shock absorption, non-corrosion, high wear and fracture resistance, low plaque uptake, and being a lighter material than metal restorations. PEEK material remains stable in the human body due to its thermal properties. It is resistant to high temperatures and is suitable for many sterilization methods. It is a chemically inert material. For this reason, it has a low reaction to other materials and is insoluble in many conventional solutions. The rate of allergic reaction against PEEK material is low. Therefore, it is a good alternative for patients with metal allergies. This material in dentistry; implant material, implant abutment material, as a digital impression post on the implant, as a precision connection piece in implant supported overdenture prostheses, framework material in implant hybrid prostheses, healing cap material, framework material in fixed prostheses, temporary crown material, framework and clasp material in removable partial prostheses, occlusal splint material as can be used.
