Based in the environment of RWTH Aachen University, we rely on top level research and technology from leading research institutions in the field of medicine, materials research, production technology and surface technology. The implants are developed, tested and manufactured in Germany.
The implant material has been successfully tested several times in preclinical studies and laboratory chemistry for biocompatibility. The hydrogen produced by the degradation process is reduced to a minimum level that is tolerated by the body. This is made possible through a special alloying process and a surface modification.
Magnesium as biomaterial
Magnesium is suitable for use as an implant material. It combines the strength of a metal with the ability to be bioabsorbed. Its mechanical properties are similar those of natural bone. As a result, the implants are able to safely stabilize fractures up to the point of healing. Compared to titanium or steel implants, the negative effect of stress shielding is eliminated.
Unlike polymer materials or bioceramics, magnesium is not degraded by an inflammatory reaction but by a physiological process, where the magnesium is converted into magnesium oxide and hydrogen gas. The two reaction products are safely processed by the body and an intact bone structure is formed at the former implant site.
In the field of medical implants, the base alloy used lays the foundation for the mechanical strength and the control of the bioabsorption rate of the implants. Through targeted research and intensive monitoring, we use innovative specialized alloy systems that are optimized in terms of mechanical strength and degradation behavior.
The process from the raw material to biocompatible, bioabsorbable alloy was developed in a long-term research effort. Currently we use two alloys: One magnesium-rare earth alloy and one magnesium-calcium-zinc alloy.
Through the use of special tools in implant manufacturing, we achieve highest accuracies and no influence on the bioabsorption. Innovative use of additive production (“3D printing”) additionally enables us to realize customized, patient specific solutions with our partners.
The combination of the two technologies allows Medical Magnesium to develop bioabsorbable implant designs and solutions for all medical indications, where patients benefit from bioabsorbable implants.
Innovative surface conversion
For optimal tissue integration and controlled bone transformation, the surface of the implants is transformed into a ceramic, mainly consisting of magnesium oxide using an innovative process. This ceramic surface creates the matte-grey look of the implants. By slowing down the corrosion, the primary stability phase of the implant is controlled. The combination of alloy and surface technology ensures that during the initial fracture healing phase there is no influence from hydrogen gas evolution.
Quality and performance
Medical Magnesium was founded to develop products based on outstanding research. To develop and manufacture our products we rely exclusively on products and solutions with verifiable highest quality and partners with the same understanding of a functional and safe product.
All steps of the production chain are carried out according to international standards within Germany. We are in close exchange with our network of researchers and manufacturing experts to improve the implants in every possible way.
