Abstract
A process is disclosed for producing a bone implant which has at least in sections a surface structure with open pores. The positive model for the implant is moulded from a base body made of a modelling material coated at least in sections with a porous coating having a predetermined pore structure. Also disclosed is a bone implant made of metal or plastics with a local distribution of pore sizes and/or densities at the surface of the implant that corresponds to the trabecular structure of the osseous environment in which the implant is implanted.
