1. An 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 being adapted and configured for detachably fastening the dental prosthesis directly to the abutment and for detachably fastening a display element used for a digital scanning operation, the coronal section being constructed along a second central axis, wherein the second central axis extends at an angle to the first central axis;
a bore in the coronal section extending along the second central axis and having an internal thread adapted to engage a screw for releasably securing the display element to the abutment;
a first indexing element in a shell surface of the coronal section for specifying an exact orientation of the display element that is coupleable to the coronal section for the digital scanning operation, based on an orientation of the first central axis; and
a second indexing element that is designed as a second recess in the circumference of the coronal section, the second recess extends to an end of the coronal section adjacent to the apical section, wherein:
the coronal section encloses a tapered frustoconical region which widens in the direction of the apical section and in which the first indexing element is arranged,
the first indexing element is designed as a first recess in the circumference of the coronal section and the first recess extends to the end of the coronal section adjacent to the apical section, and
the first recess and the second recess are spaced from each other.
