Our invention
TisMet®
We have developed a unique surgical biomaterial that enables the production of absorbable medical devices such as screws, plates, wires and meshes. These devices are designed to fix, anchor, separate or replace natural tissue and the gradually transform back into elements naturally present in the human body.
TisMet® – Strong, Safe, Resorbable
TisMet® is a magnesium-calcium biomaterial that behaves like titanium or steel: drillable, bendable, screwable, following standard surgical routines. Once it has supported the healing, it safely resorbs, eliminating the need for removal.
Free from rare earth metals, TisMet® offers best-in-class mechanical strength and controlled degradation, thanks to ultra-high-purity magnesium with impurities below 2 ppm.
Developed with patented ETH Zurich technology, TisMet® combines decades of biomaterials research to deliver predictable, reliable clinical performance.

Before 2000
minor clinical Mg activities, hydrogen problem of Mg could be reduced by the use of rare earths
2020
Human clinical trial of ultrahigh-purified Mg-Zn-Ca

TisMet™ BC excellent osseointegration optimizing bone contact
Magnesium was first used in surgery performed on humans over 100 years ago.
Later, magnesium alloys were produced, mainly for technical lightweight applications. These alloys were then successfully used as implant material, one alloy even is used until today. Today, after years of development, an alloy is manufactured free from rare earth metals and fully ISO 13458 certified.
