Abutment for holding a dental prosthesis to a jaw implant, having: an apical section for detachably fastening the abutment to the jaw implant, the apical section being structured along a first central axis; a coronal section for detachably fastening the dental prosthesis to the abutment, the coronal section being structured along a second central axis, wherein the second central axis extends at an angle to the first central axis; a borehole in the coronal portion extending along the second central axis and having an internal thread adapted to engage a screw for detachably fixing an indicator element having an axial borehole to the abutment or to engage a screw for detachably fixing a dental prosthesis to the abutment; a first indexing element in a shell surface of the coronal section for specifying an orientation of a display element that is coupleable to the coronal section for a digital scanning operation, based on a unique orientation of the first central axis; wherein the first indexing element is formed as a recess, so that the shell surface has an irregular course, and the first indexing element interacts with the display element in such a way that the orientation of the apical section is predetermined for the display element by positive locking of the first indexing element and an indexing coupling of the display element; a second indexing element, which is formed as a second recess in the circumference of the coronal portion; and wherein the coronal portion surrounds a truncated cone-shaped area which widens in the direction of the apical portion and in which the indexing elements (24a, 24b) are arranged; the coronal section is suitable and provided so that both a dental prosthesis is attachable to the coronal section and the display element is coupleable for a digital scanning operation; the first indexing element is formed as a first recess in the circumference of the coronal section; a delimiting surface of the first recess or the first and second recesses extends parallel to the second central axis; and the delimiting surface comprises an undulated structure which is preferably symmetrical with respect to a plane of symmetry of the first or the first and second recesses, wherein the delimiting surface is undulated in a direction which is perpendicular to and spaced from the second central axis. an apical section for detachably fastening the abutment to the jaw implant, the apical section being structured along a first central axis; a coronal section for detachably fastening the dental prosthesis to the abutment, the coronal section being structured along a second central axis, wherein the second central axis extends at an angle to the first central axis; a borehole in the coronal portion extending along the second central axis and having an internal thread adapted to engage a screw for detachably fixing an indicator element having an axial borehole to the abutment or to engage a screw for detachably fixing a dental prosthesis to the abutment; a first indexing element in a shell surface of the coronal section for specifying an orientation of a display element that is coupleable to the coronal section for a digital scanning operation, based on a unique orientation of the first central axis; wherein the first indexing element is formed as a recess, so that the shell surface has an irregular course, and the first indexing element interacts with the display element in such a way that the orientation of the apical section is predetermined for the display element by positive locking of the first indexing element and an indexing coupling of the display element; a second indexing element, which is formed as a second recess in the circumference of the coronal portion; and wherein the coronal portion surrounds a truncated cone-shaped area which widens in the direction of the apical portion and in which the indexing elements (24a, 24b) are arranged; the coronal section is suitable and provided so that both a dental prosthesis is attachable to the coronal section and the display element is coupleable for a digital scanning operation; the first indexing element is formed as a first recess in the circumference of the coronal section; a delimiting surface of the first recess or the first and second recesses extends parallel to the second central axis; and the delimiting surface comprises an undulated structure which is preferably symmetrical with respect to a plane of symmetry of the first or the first and second recesses, wherein the delimiting surface is undulated in a direction which is perpendicular to and spaced from the second central axis.
