A process for surface treatment of metal substrates, including the steps of: providing a metal substrate including hydroxyl groups at its surface; bringing the metal substrate into contact with a solution of at least one organophosphorus compound to enable the reaction of the hydroxyl groups at the surface of the metal substrate with the organophosphorus compound to form a monomolecular layer over the surface and a second layer of physisorbed organophosphorus molecules at least preponderantly crystallized, the obtained treated substrate being coated with the organophosphorus compound in the form of a first monomolecular layer coating at least 15% of the surface of the substrate and in the form of a physisorbed second layer at least preponderantly crystallized. A treated metal substrate which may be obtained by the process thereof, corresponding solution and its use for treating metallic substrates to improve their tribological properties during their shaping, in particular their stamping.

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.
