SINTX Technologies Expands Silicon Nitride Platform into Hybrid CFR-PEKK Trauma Plates
SINTX Technologies, Inc./US, an advanced ceramics innovator specializing in silicon nitride (Si3N4) for musculoskeletal applications, announced the publication of a peer-reviewed study in the Journal of the Mechanical Behavior of Biomedical Materials. The study validates the use of silicon nitride (Si3N4) surface coatings on carbon fiber-reinforced polyetherketoneketone (CFRPEKK) trauma plates – marking a significant expansion of SINTX’s biomaterial platform into additively-manufactured polymer-carbon-ceramic constructs. The research, supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) of the National Institutes of Health (NIH) (Award R41AR082266), was conducted in partnership with Prof. Steven Kurtz’s Implant Research Center at Drexel University’s School of Biomedical Engineering, Science, and Health Systems.
“This work demonstrates that SINTX’s proprietary process can successfully integrate silicon nitride into 3D-printed continuous carbon fiber (CCF) PEKK composites without compromising flexural strength or stiffness,” said Dr. Ryan Bock, Chief Technology Officer at SINTX, principal investigator on the project, and co-author of the study. “Notably, certain layup configurations of these hybride manufactured CFR-PEKK plates were engineered to replicate the mechanical stiffness of cortical bone – highlighting a key advantage over traditional metallic trauma plates. We are enthusiastic about the clinical potential of these materials and the significant market opportunity they represent for SINTX.”
The Company expects similar results can be obtained with a wide variety of other thermoplastics, including polyetheretherketone (PEEK). This particulate embedding approach represents an additional way to impart silicon nitride’s beneficial biologic properties to conventional inert biomaterials.
“The significance of this study is twofold – it affirms that silicon nitride can be effectively integrated with novel thermoplastic-based biomaterials, and it supports our broader vision of combination materials tailored for specific clinical applications”, said Eric Olson, CEO of SINTX Technologies. “By enabling silicon nitride to work in concert with polymers like CFR-PEKK, we are positioning ourselves to be the material difference in addressing unmet needs in orthopedic trauma, spine, and custom surgical implants.”
