Sintx Technologies, Inc.

SINTX Technologies is an advanced ceramics company formed in December 1996 that develops, manufactures, and commercializes silicon nitride biomaterials, composites, devices, and related technologies. The company provides biomedical solutions specializing in silicon nitride (Si₃N₄) for musculoskeletal and antipathogenic applications. SINTX also manufactures silicon nitride parts for customers in the electrical, aerospace, and other industrial sectors. SINTX is a global leader in silicon nitride research, development, and manufacturing, with products implanted in humans since 2008. SINTX's core business focuses on medical grade silicon nitride for biomedical applications. Its biomedical products are biocompatible, bioactive, antipathogenic, and demonstrate superb bone affinity. Spinal implants made from SINTX silicon nitride have been successfully implanted in humans since 2008 in the U.S., Europe, South America, and Asia. This established use, along with resistance to bacterial adhesion and bone affinity, suggests suitability for other fusion device applications like arthroplasty implants, foot wedges, and dental implants. In October 2025, SINTX received U.S. Food and Drug Administration (FDA) 510(k) clearance for the SiNAPTIC® Foot & Ankle Osteotomy Wedge System, enabling commercial entry into reconstructive foot and ankle surgery in the United States. SINTX silicon nitride products can be polished for articulating applications, such as bearings for hip and knee replacements.
