Abstract
The invention provides a process for producing a metal body, which leads in a simple and reliable way to formation of a defined surface topography, if desired also combined, in the range from 10 nm to 500 μm on a metal base body or blank which is to have, in particular, nanoscale pores. For this purpose, a pulsating current is applied to a metal base body in an electrolysis bath, with the electrolysis bath comprising salt former ions matched to the material of the metal base body. Furthermore, the invention provides a dental implant having particularly advantageous surface properties, in which a nanostructure is superimposed on a surface microstructure and nitrogen atoms and/or nitrogen compounds are attached and/or included in the region of the surface.
