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.
