Evonik introduces two PEEK grades for long-term dental prosthetics
Amid growing demand for alternatives to metal-alloy materials for dental bridges and fixed or removable restorations, German chemicals company Evonik has introduced two polyether ether ketone (PEEK) grades, Vestakeep DC4760 and Vestakeep DC4780, for long-term dental prosthetics, expanding its range of metal-free, lightweight dental materials. Developed by its High-Performance Polymers business line, the grades combine bone-like stiffness, durability, biocompatibility and processability for dental laboratories.
According to Marc Knebel, head of Evonik’s Peek medical applications team, their natural colour, neutral taste and low weight make them suitable for patients seeking metal-free options. Both grades use a patented formulation designed to provide high structural rigidity. An independent study published in Dental Materials, conducted by researchers from Charité – Universitätsmedizin Berlin and the Einstein Center Digital Future, found that their stiffness was sufficient for implant-supported dentures and other high-load dental prosthetics.
