Claim:
1. A process for producing an implant having a functional surface, wherein a base body and the functional surface are produced in one work step; wherein the process comprises the steps of: (a) preparation of a ceramic powder mixture; (b) adding to the ceramic powder mixture a plastic binder system, wherein the plastic binder system is adapted to a subsequent molding process, and the ceramic powder mixture with the plastic binder system forms a first feedstock; (c) dividing the first feedstock and adding aggregates to a part of the feedstock to form a second feedstock; (d) carrying out a molding process, wherein the base body and the bone-affine surface are molded from the first and second feedstock, wherein the molding process is a high or low pressure injection molding process or an extrusion process (e) debinding of the green part; (f) sintering and debinding of the brown part of the implant molded in the previous step to yield the finished implant with a bone-affine surface.
