In-Vivo Performance of Bioabsorbable BioMg 250 Implants
Abstract: The invention and alloy design principles of a bioabsorbable Mg alloy implant will be described. The alloy was designed to utilize addition elements odd in atomic size and electronegativity from the Mg atom, yet osteo-productive and as nutrients to the body. This alloy performed well in early toxicity and in vitro corrosion testing. Subsequent in vivo campaigns in rabbit femur and canine mandible models will be described. Micro CT and histology evaluations of these experiments will be presented, confirming promise in comparison to commercial Titanium and Polymer implants.
