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

Journal of Advanced Research, 2021
Background: The polyetherketoneketone (PEKK) and polyetheretherketone (PEEK) are the two most well-known of the polyaryletherketone (PAEK) family. PEKK is a new evolving polymeric material.

Dual reinforcement of PEKK composites with hydroxyapatite and silicon nitride nanowires for enhanced mechanical, tribological, antibacterial, and osteogenic performance [PDF]

Journal of Nanobiotechnology
Polyetherketoneketone (PEKK) has attracted interest for load-bearing orthopedic implants due to its favorable elastic modulus and radiolucency; however, its biological inertness and weak interfacial bonding limit its clinical application.

Designing Superhydrophilic 3D Porous Surfaces on Polyetherketoneketone Surfaces to Promote Biocompatibility [PDF]

Journal of Functional Biomaterials
Polyetherketoneketone (PEKK) exhibits satisfactory mechanical properties and biocompatibility, with an elastic modulus closely resembling that of natural bone. This property reduces the stress-shielding effect associated with bone implants.
