Implant and method for producing an implant

摘要

An implant is provided with a main body (1) and with a double coating applied to at least one surface section of the main body (1), wherein the double coating comprises an adhesion promoter layer (2), applied directly to the at least one surface section of the main body, and of an osteointegrative layer (3) covering the adhesion promoter layer (2). The layers (2;3) consist of pure titanium, wherein the adhesion promoter layer (2) has a thickness of 2-6 μm, in particular a thickness of 3-5 μm, and the osteointegrative layer (3) has a thickness of 50-70 μm, in particular of 55-65 μm. Moreover, the osteointegrative layer (3) has a porosity of 70-90% and a roughness Rz of at least 45 μm. A related method is also provided for producing such an implant.

1. An implant having a main body including an outer surface having a roughened portion and a non-roughened portion that surrounds the roughened portion, the implant comprising a double coating applied to the roughened portion, wherein the double coating comprises:
an adhesion promoter layer directly applied to the roughened portion; and an osteointegrative layer covering the adhesion promoter layer, the osteointegrative layer being adapted to contact a bone of an animal or a human body upon insertion of the implant into the animal or the human body, wherein the adhesion promoter and osteointegrative layers comprise pure titanium, the adhesion promoter layer comprises a thickness of 2-6 μm, the osteointegrative layer comprises a thickness of 50-70 μm, and the osteointegrative layer has a porosity of 70-90% and a roughness Rz of at least 45 μm.
