Biodegradable Metals: State of the Art

Abstract

Degradable biomaterials constitute a novel class of bioactive biomaterials which are expected to support healing process of a diseased tissue and to degrade thereafter. Two classes of metals have been proposed: magnesium- and iron-based alloys. Three targeted applications are envisaged: orthopaedic, cardiovascular and pediatric implants. Conceptually, biodegradable metals should provide a temporary support on healing process and should progressively degrade thereafter.
