| 摘要 |
The present invention relates to an abutment of a dental implant system for connecting a dental implant and a suprastructure, said abutment comprising an abutment basic body extending from an apical end to a coronal end arranged opposite to the apical end. The abutment basic body comprises a dental implant connecting portion facing the apical end and adapted to fit with a corresponding abutment connecting portion of the dental implant and/or an intermediate part to be directly or indirectly connected with the dental implant. It further comprises a support portion facing the coronal end and designed such to allow the suprastructure to be mounted directly or indirectly. According to the invention, the abutment further comprises nanostructures formed on at least a portion of the outer surface of the abutment basic body, said nanostructures extending in at least two dimensions to 200 nm at most. |
