| 摘要 |
The invention relates to an implant with a main body (1) and with a double coating applied to at least one surface area of the main body (1), wherein the double coating consists of an adhesion promoter layer (2), applied directly to the at least one surface area of the main body, and of an osteointegrative layer (3) covering the adhesion promoter layer (2), and these 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. The invention further relates to a method for producing such an implant. |
