Permanent implants are often much stiffer than the bone they are supporting, which can lead to loss of bone density, mechanical failure of the implant, and require corrective surgery. Biodegradable orthopedic implants offer strength and stiffness close to that of bone, prevent the need for corrective surgery, and eliminate the long-term existence of a foreign object in the body. In this work, in vitro corrosion of magnesium-samarium(III) oxide nanocomposites are studied for their use as biodegradable orthopedic materials. The Mg-1%Sm2O3 nanocomposite shows a promising corrosion rate, lower than pure magnesium. Additive manufacturing of zinc paste is also explored as a medium for fabrication of patient-specific implants. This work provides insight into the development of magnesium-based nanocomposites as biodegradable materials.","abstract_html":"Biodegradable metals and alloys are materials that are intended to remain in the body long enough for healing to occur, and then degrade or dissolve after their service lifetime.
