Metal-Free Alternative “Revolutionary PEKK”: An Emerging Material for Removable and Fixed Prosthesis Usage in Dentistry: A Critical Review

Abstract

Polyaryletherketone polymers have been widely used for biomaterials in orthopaedic, trauma, and spinal implants. Polyaryletherketone has three different variants viz: Polyetheretherketone (PEEK), Polyetherketoneketone (PEKK) and Polyetherketone (PEK). In this research work, an emergent critical review of the material (PEKK) which are used in removable and fixed prosthesis in dentistry. The following databases were identified in systematic research which comprises certain inclusion and exclusion criteria. The databases are EMBASE, cochrane library, MEDLINE, PUBMED, Ovid MEDLINE, web of science. This study assesses the eligibility screening, data extraction and quality assessment. Many studies were assessed to improve PEKK containing osseointegration, surface modification of PEKK, etc. In animal models, in vivo studies were performed. To the best of my knowledge any author targeted for the evaluation of the removable and fixed prosthesis usage of PEKK as a biomaterial. This review showed that the wide application of PEKK is used in different aspects of dentistry. The PEKK materials in comparison of PEEK have suitable physical, mechanical, and chemical qualities (discussed in details in following sections) and can be employed in a variety of applications, including framework for an implant-supported and crown and bridge fixed prosthesis, endo crowns, restorative material, and dental biomaterial implants. Wider uses in clinical dentistry may also result from modifications and improved material qualities. As PEKK has only lately been used in dentistry and there are little research available, long-term evaluations are required for extensive validation of the same.
