ABSTRACT:
An auditory ossicle prosthesis is described comprising a plate (1) with a groove (7) applied to its upper side and a shaft (2) eccentrically applied to its lower side. The prosthesis consists of a bioactive material and contains additionally at least in one partial area an insoluble bioinert material, which is applied mainly as a coating material in the form of an additive layer (S(+)) or a subtractive layer (S(-)). Suitable coating processes and substances are disclosed. If S(-) layers are applied, they may be exposed subsequently to a sealing and/or silanizing treatment.
