| Abstract Scope |
Degradable metallic biomaterials have shifted the established paradigm of metallic biomaterials from being corrosion-resistant to having controlled degradation. Degradable implants have been considered promising candidates for treating bone fractures as they eliminate the requirement of secondary surgery and help in pediatric bone growth. Fe, Mg, and Zn-based alloys have been extensively studied due to their low density and favorable mechanical and biological properties. However, Mg's strength, ductility, degradation rate, and hydrogen gas evolution are still a concern. Pure Fe-bearing implants provide good mechanical support, but a lower degradation rate is an issue. This presentation will focus on the degradation rate of both Mg and Fe-based systems. We will discuss the improvement in corrosion resistance of Mg-based systems as well as improving the corrosion rate of Fe-based systems. The effects of corrosion and alloy composition on in vitro cytocompatibility and in vivo biocompatibility will also be discussed. |
