ABSTRACT:
The invention features a method for preparing coated implants. The method includes the steps of: (a) providing a gel of amorphous calcium phosphate having a calcium to phosphorous ratio of 0.5 to 1.6; (b) dispersing the gel of amorphous calcium phosphate in an aqueous liquid to form a colloidal mixture which is between 60% and 99% by weight water; (c) immersing an implant to be coated in the colloidal mixture; and (d) with the implant acting as an anode, electrodepositing material in the colloidal mixture on the implant to form a substantially uniform coating.
