ABSTRACT:
The present invention provides a method for growing or depositing artificial bone materials called organoapatites on a metal surgical alloy. The method involves pretreating the alloy with at least one aqueous solution of a poly(amino acid). After this pretreatment step, the organoapatites can be synthesized onto the alloy. Because most surgical implants are made from metal alloys, this method can be used to make implants which contain organoapatites may promote the formation of natural bone when placed into a human patient in vivo.
