Abstract
The invention provides a nanotechnology process for implant surface treatment for producing an implant article. The nanotechnology process comprises subjecting a non-porous material to a mechanical or chemical surface treatment until a surface roughness with an average peak distance (Ra value) between 10 and 1,000 nm is obtained. The roughened surface can subsequently be subjected to precipitation of calcium phosphate from a solution containing calcium and phosphate ions.
Claims8
A process for producing a calcium phosphate coated implantable device, comprising subjecting a porous or non-porous material to a surface treatment until a roughened surface with an average peak distance between about 10 nm and about 1,000 nm is obtained and in vitro coating the surface with a layer of a calcium phosphate.
