| Abstract Scope |
Of various metallic elements, Mg is considered one of the most feasible biodegradable materials since it can be excreted in the urine after degradation in the body. However, commercially available Mg and its alloys generally suffer from more rapid and localized degradation than other biodegradable materials in an aqueous environment containing salts like seawater or blood, resulting in their premature decay after implantation. Furthermore, H2 gas bubbles generating during rapid degradation of Mg can cause inflammation by creating cavities on the tissue. Here, as an alternative to the conventionally available Mg-based materials, the authors suggest a new type of Mg alloy with highly enhanced corrosion resistance, giving expectations to exclude the active biodegradation after its implantation. In this study, in vitro and in vivo biodegradation behavior of the experimental and commercial Mg alloys was comparatively investigated to see the possibility of the new material in future biodegradable implant applications. |
