Polyaryletherketone (PAEK) is recently introduced in dentistry. The polymer has superior mechanical and chemical properties compared to previous dental materials. PAEK has been explored for lots of applications for clinical dentistry. The prostheses can be made by the injection molding or milling techniques. Recent studies focus on improving the bioactivity of PAEK and expanding the application. The purpose of this article is to introduce the basic features, chemical structure and various clinical applications in fixed dental prostheses. Further research and clinical trials will be needed to confirm the usability of PAEK in the routine practice.

Although many prosthetic materials exist for fabrication of implant-supported telescopic overdentures, available materials have not been thoroughly evaluated from a functional standpoint. This case report describes the use of polyaryletherketone (PAEK) based polymer for an implant-supported telescopic overdenture, a seldom used material in dentistry. This material is lighter than traditional materials, can accommodate changes in retentive forces, and is an easily retrievable by CAD/CAM fabrication. This case highlights the possibility of using new polymer materials for implant-supported telescopic overdentures.

It is necessary to set the correct occlusal plane and to distribute the occlusal force uniformly considering the state of the opposing dentition during the prosthetic of the single edentulous patient with severe alveolar bone resorption. Implant supported overdenture is superior to complete denture in terms of maintenance and stability, and limited implants are used in fully edentulous patients with high alveolar bone resorption. Telescopic attachments using a newly introduced material based on poly-aryl-ether-ketone (PAEK) have the advantages of typical telescopic copping, excellent abrasion resistance, and are lighter and more economical than conventional implant overdentures. In this case, we restored maxillary arch with a implant retained overdenture using the telescopic attachment made of Pekktonand the mandible was restored with fixed implant prosthesis. Through these procedures esthetic aspects and functional outcomes were satisfactorily achieved.
