Abstract: A dental implant having a prosthetic interface in its cervical region, a core and at least one thread extending from the cervical region to an opposite apical region, the thread having recesses on which a cutting edge for cutting bone is arranged, the respective cutting edge is arranged in the thread direction at the rear side of the recess, wherein the respective recess comprises a cutting area at which the cutting edge is arranged and a compacting area adjacent to the cutting area for compacting bone tissue.

Abstract: The invention relates to a device for turning over sheet material, in a printing machine, such as verso-printing in an electrophotographic printing machine. The device includes driven web-shaped segments extending essentially parallel to each other over at least one section, such that the web-shaped segments clamp the individual sheets between the segments and turns over each sheet as it is transported along a transport path.

Abstract: The invention relates to a device for turning over sheet material, preferably sheets of printing material, in a printing machine, preferably for verso-printing, preferably in a digital printing machine, preferably an electrophotographic printing machine, said device comprising driven web-shaped segments extending essentially parallel to each other over at least one section, said web-shaped segments clamping the indi-vidual sheet between them and thus transporting said sheet along a transport path, thus turning over said sheet. The object of the invention is to provide a turn-over device of the aforementioned type, which grasps the sheets with the belt segments and guides them in a manner so as to be turned over, in an easier and more secure manner.
