The research in the biocompatibility of materials started at the beginning of the 1960'ies. Indeed, the first toxicological results proved the incompatibility of metallic implants with the human metabolism. Research then concentrated in finding immuno- and biocompatible materials, whose biochemical and mechanical characteristics ought to be outstanding. Lately, researchers have started using different sorts of ceramics, of which Zirconium has revealed the most remarkable results. It has shown the best biological response, its harmlessness having been proven.
These ceramic implants belong to the SIGMA range. A manufacture protocol has been established for each series of the SIGMA products, the latter are submitted to regular and rigorous tests. They are all CE and ISO certified.
All SIGMA implants are corrosion proof, chemically and electrically neutral and their colour guarantee aesthetic perfection. Moreover, being completely radio-opaque, it neither interferes with security scanners nor with nuclear-magnetic resonance images (NMRI).
