The present invention provides Dental implant configured to be inserted into a hole in jaw bone and to be at least partially situated in bone tissue when implanted, comprising: a coronal implant region, the surface of which is at least partly covered by an oxide layer with an average thickness in the range from 60 nm to 170 nm and has an average arithmetical mean height Sa in the range from 0.1 μm to 1.0 μm. Further provided is a component for dental applications, preferably dental abutment, wherein the surface of the component is at least partly covered by an oxide layer with an average thickness in the range from 60 nm to 170 nm and has an average arithmetical mean height Sa in the range from 0.05 μm to 0.5 μm and an implant system comprising the dental implant and the component. Method for forming a protective layer on the surface of an implantable or implant component, the method comprising a) applying a solution on the surface of component, the solution having a pH at 25° C. of 6.8 or less and b) drying the solution applied in step a) to form a protective layer on the surface of the component for dental applications. Finally, part of the present invention is an implantable or implant component having a protective layer obtainable as above and a use of such layer for storage.

A method and a device that determines surface characteristics of a stent to be implanted in a lumen in a body in which a wetting behavior of a stent surface serves as measure for the surface characteristics of the stent surface. In order to determine the wetting behavior, a course of a wetting force along a length of the stent surface is determined, the wetting power between the stent surface and a liquid surface being detected along the length of the stent.
