Metal Implants for Hard Tissue Restoration

Metals with biodegradation characteristics are considered to be unique biomaterials which orthopedic surgery (including bone-grafting therapies) can rely on. Implants made of either such metals or their metal alloys represent an important category since those metals have reliable mechanical and corrosion properties. However those metals suffer from bioactivity. Hence coating of such substrates (metals and related alloys) with proper bioactive materials such as calcium phosphate is of prime importance to offer bioactivity and reasonable corrosion control. In this context calcium phosphates (CaP) are known of its biocompatibility and bioactivity in bone growth directed to biomedical treatment of bone defects and fractures.
