Overview

SINTX Technologies is an advanced ceramics company formed in December 1996, that develops and commercializes materials, components, and technologies for medical and agribiotech applications. SINTX provides biomedical solutions for medical devices specializing in silicon nitride (Si₃N₄) for musculoskeletal and antipathogenic applications. 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 July 2025, SINTX submitted a 510(k) premarket notification to the U.S. Food and Drug Administration (“FDA”) for its novel silicon nitride osteotomy wedges, marking its official entry into the foot and ankle reconstruction market. These next-generation implants blend cutting-edge biomaterials science with surgical precision and are designed to elevate standards in orthopedic procedures. Bacterial infection of any biomaterial implants is always a concern. SINTX silicon nitride has been shown to be resistant to bacterial colonization and biofilm formation, making it antibacterial. SINTX silicon nitride products can be polished to a smooth and wear-resistant surface for articulating applications, such as bearings for hip and knee replacements.

We believe that silicon nitride has a superb combination of properties that make it suited for long-term human implantation. Other biomaterials are based on bone grafts, metal alloys, and polymers- all of which have well-known practical limitations and disadvantages. In contrast, silicon nitride has a legacy of success in the most demanding and extreme industrial environments. As a human implant material, silicon nitride offers bone ingrowth, resistance to
