Patent ID: 8734889

Claim:
A method for the production of a ceramic implant with a structured, porous surface having biocompatibility, for at least partial insertion into hard tissue and/or into soft tissue followed by osteointegration or osseointegration therewith, comprising: surface modifying the ceramic material on a ceramic surface area of said ceramic implant in a salt melt at least in the regions of said ceramic implant that are to be exposed to bone and/or soft tissue, if appropriate after a previous surface modification, involving removal of ceramic material, wherein the implant is structured on the ceramic surface area by etching in said salt melt, and wherein the etching in said salt melt changes the topography of the ceramic surface and forms a porous surface, and involves essentially only a removal of some ceramic material from the entire surface of said ceramic surface area while retaining other ceramic material on said entire surface of said ceramic surface area; and whereby a resulting final ceramic implant product comprises said porous ceramic surface with changed topography and having said biocompatibility without a coating of apatite.
