Abstract
The use of inert materials (light alloys) for orthopaedical implants to overcome bone failures has suffered a displacement by bioactive materials with composition similar to the bone (calcium phosphate ceramics). Nevertheless, it has been necessary to combine the mechanical properties of the metal alloys and the resemblance of the human tissues of the bioceramics that promotes the growth of the living tissue and the osteointegration of orthopaedical implants. Though, a new solution emerged based on combining the mechanical properties of the bulk material (metal alloy) and the physico-chemical properties of the bioactive surface.The use of inert materials (light alloys) for orthopaedical implants to overcome bone failures has suffered a displacement by bioactive materials with composition similar to the bone (calcium phosphate ceramics).
