| Abstract Scope |
Biodegradable implants are of great interest in biomedical research as they can eliminate the need for secondary surgeries to remove permanent implants. Magnesium (Mg) alloys are strong candidate materials due to their biocompatible, osteoconductive, biodegradable, and mechanical properties. However, 3D printing of Mg alloys is challenging as they oxidize easily, and their vapor is pyrophoric. Our research focuses on designing, fabricating, and characterizing biodegradable 3D porous textiles for craniofacial defects, biliary stents, and sternal fixture using magnesium alloy wires.
We quantify the mechanical properties of these structures including stiffness and strengths to understand if they are compatible with the requirements of a specific application, and we study their corrosion behavior in vitro under static and cyclic loading conditions, characterizing average corrosion rates and pitting factors. Mechanical and corrosion results obtained for weaves and wires will be presented, along with some small animal model in vivo data. |
