FleX SN-MC2: What is it?


SINTX’s FleX SN-MC2 is the only dense silicon nitride material with a history of experimental and clinical data (over 130 peer-reviewed publications) to support its use inside the body. It is also the only silicon nitride material used in FDA-cleared medical implants.

Beneficial Properties of Silicon Nitride (FleX SN-MC2):

Spinal Implants

With over 40,000 human spine implantations over the past 10 years and a very low percentage of reported adverse events, FleX SN-MC2 has an excellent safety record8. It is biocompatible, bioactive, and has shown bacterial resistance and superb bone affinity4.

Dental Implants

As a dental implant material, FleX SN-MC2 has been thoroughly tested to ISO 10993-01 standards and been shown to be highly biocompatible5,13,14. Silicon nitride is metal free, like all ceramics, and free of corrosion, galvanism, and electronic disturbances.


When compared to other biomaterials, FleX SN-MC2 has been shown to remove oxygen from the tribo-layer22,23,24,25, potentially avoiding long-term degradation of polyethylene in hip and knee replacements and extending the life of these synthetic joints.
