Darmstadt, Germany. Evonik has introduced two new PEEK grades designed for use in long-term dental prosthetics. One of the latest developments from its High Performance Polymers business line, VESTAKEEP® DC4760 and VESTAKEEP® DC4780 feature remarkable bone-like stiffness, durability, high biocompatibility and excellent processability in dental labs, enlarging the portfolio of metal-free and lightweight dental materials
“The launch of these two new VESTAKEEP® grades are in line with Evonik’s strategy to serve a growing consumer interest in a greater range of metal-free materials for manufacturing dental bridges or long-lasting fixed and removable prosthetic restorations,” said Marc Knebel, head of the PEEK medical applications team at Evonik’s High Performance Polymers business line. “Thanks to their natural color, neutral taste and lightweight properties, PEEK-based dental frameworks are greatly valued by patients looking for an alternative to metal-alloy based materials.”
The new dental grades join an existing range of VESTAKEEP® products for dental applications and are based on a patented formulation that brings high structural rigidity. This property was further defined in an independent study recently published in “Dental Materials.” Conducted by leading members of Charité University Medicine in Berlin and the Einstein Center Digital Future research group, the analysis found VESTAKEEP® DC4760 and VESTAKEEP® DC4780 to have a level of stiffness high enough for use in implant-supported dentures and other high-load dental prosthetics.
“The key feature of these new VESTAKEEP® dental grades is their combination of higher stiffness and their ability to maintain the flexural strength expected for long-term dental prostheses. Thanks to this, VESTAKEEP® can now be used for a broader range of high quality, aesthetic & long-lasting multi-unit frameworks that provide elevated patient comfort” said Jacques-Antoine Raust, Business Manager in Evonik’s Medical Systems team.
Both VESTAKEEP® DC4760 and VESTAKEEP® DC4780 feature excellent polishability for improved machining with established dental laboratory equipment. This allows the benefit of a smooth and immediate integration into daily operations for dental lab technicians and dentists. Evonik’s new PEEK grades continue to retain previous dental grades’ well-established, excellent wear and plaque accumulation resistance for durable hygiene and aesthetics. Additionally, the increased stiffness of both products leads to better modulus matching between acrylic veneers and PEEK, which can increase the longevity of dentures
VESTAKEEP® DC4760 (dentin colored PEEK) and VESTAKEEP® DC4780 (gingiva colored PEEK) are available as rods or CAD/CAM discs with full biocompatibility for long-term mucosal contact. Along with the product, Evonik will provide customers regulatory support for their own MDR registration.
Evonik’s experts will also present their latest solutions for medical applications from November 16 to 19 at the COMPAMED trade show, Hall 8B, Booth D04, in Düsseldorf, Germany.
