Sintx Technologies, Inc.

SINTX Technologies SINTX Technologies is an advanced ceramics company formed in December 1996 that develops, manufactures, and commercializes silicon nitride biomaterials, composites, devices, and related technologies for medical and other high-value applications. SINTX provides biomedical solutions for medical devices specializing in silicon nitride (Si N ) for musculoskeletal and antipathogenic applications. We also manufacture parts made from silicon nitride for customers in the electrical, aerospace and other industrial sectors. SINTX is a global leader in the research, development, and manufacturing of silicon nitride, and its products have been implanted in humans since 2008. SINTX Core Business Biomedical Applications : Since its inception, SINTX has been focused on medical grade silicon nitride. SINTX biomedical products have been shown to be biocompatible, bioactive, antipathogenic, and to have 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 its inherent resistance to bacterial adhesion and bone affinity suggests that it may also be suitable in other fusion device applications such as arthroplasty implants, foot wedges, and dental implants. More recently, in October 2025, SINTX received U.S. Food and Drug Administration (FDA) 510(k) clearance for the SiNAPTIC Foot & Ankle Osteotomy Wedge System, enabling SINTX’s commercial entry into reconstructive foot and ankle surgery in the United States.
