Polyetherketoneketone (PEKK): An emerging biomaterial for oral implants and dental prostheses

The polyetherketoneketone (PEKK) and polyetheretherketone (PEEK) are the two most well-known of polyaryletherketone (PAEK) family. PEKK is a new evolving polymeric material. biomaterials an elastic material with good shock absorbance fracture resistance present ultra-high performance among all thermoplastic composites for excellent mechanical strength, chemical resistance, high thermal stability. aim this review to comprehensive overview its various applications in restorative, prosthetic, implant dentistry highlighting prospects clinical applications. Available articles on dental were reviewed from January 1957 August 2020) using MEDLINE/PubMed, Web Science, ScienceDirect resources. presents suitable physical, mechanical, properties prosthodontics oral implantology. has potential wide range applications, including tooth restorations, crowns, bridge, endoposts, denture framework, implant-supported fixed prosthesis, implants. implants have shown lesser stress shielding compared titanium Further modifications improving can result broader field dentistry. Long term evaluations needed as recently applied dentistry, there limited studies published PEKK.
