Innovative materials in medicine and dentistry

Background: Polyaryletherketone (PAEK) materials are semi-crystalline biopolyesters with excellent mechanical and chemical properties. Polyaryletherketone has good chemical resistance and high temperature stability, low water absorption, light weight, good processability, injection molding and extrusion, self-lubricating. Also it is metal - free, biostable, sterilization compatible, biocompatible, has elasticity similar to the bone’s, x-ray transparency, and wearing comfort. The purpose of the study was to present the polyaryletherketone as a contemporary material for prosthetic and implantology treatment in the medicine and dentistry. Materials and methods: The material for this study was obtained with extensive search from relevant literature. Results: Polyaryletherketone is used in different fields of medicine such as: Cranial–Maxillo-Facial surgery, Cardiology, Orthopedics, Dentistry. It is used in different places for application such as spinal cages, joints, implants for cartilage, bone implants for bone fractures, stents, heart valves, suture anchors, interference screws. In dentistry polyaryletherketone is used for various types of metal free products: metal free crowns, telescopic crowns, metal free bridges, gingiva formers, abutments, dental attachments, partial dentures clasps, occlusal splints, inlay, onlay, bases of dentures, dental bar restorations. Conclusion: Polyaryletherketone has wide application in medicine and dentistry, primarily because it is not allergenic material, it’s biocompatible and acceptable for the organism.
