Abstract

A process for manufacturing a ceramic implant with a surface which forms a permanent bonding to bone cell tissues, the surface providing improved osseointegration, the process comprising the step of:—a pretreatment of the ceramic material with the surface wherein said surface of the ceramic material is exposed to a conditioning plasma, which is produced by means of direct current (DC) or alternating current (AC), such as high or radio frequency (HF, RF), or microwaves (MW) at a low pressure, followed by a second step;—a treatment with a reactive plasma in which an organic compound is added to the plasma for the at least partial application of an organic phase to said surface wherein the organic compound is selected from the group consisting of aliphatic amines, cyclic amines, unsaturated and aromatic amines as well as combinations thereof.
