<p>The use of resorbable metallic biomaterials for temporary implants has increased dramatically in the last decade. Degradable biomaterials are desirable in some specific pediatric, orthopedic, and cardiovascular applications, in which they may overcome the disadvantages of permanent devices. The three main biodegradable metals: Mg, Fe, and Zn, are intensively studied as temporary orthopedic implant materials.
