Abstract: An abutment for holding a dental prosthesis to a jaw implant, having: an apical section detachably fastening the abutment to the jaw implant, the apical section being structured along a first central axis; a coronal section 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; and an indexing element in a shell surface of the coronal section specifying an orientation of a display element that is coupleable to the coronal section for a digital scanning operation, based on an orientation of the first central axis. A display element coupling to an abutment coronal section, and displaying a position and orientation of the abutment for a digital scanning operation, a tooth model system having an abutment and a display element, and a method producing a dental prosthesis.

Abstract: The invention relates to a holding system having a holding device (1) and an abutment blank (6), to a method for retaining and machining an abutment blank (6), and to a holding device (1) for retaining an abutment blank (6) having an implant interface (8) and a retainer segment (7) spaced apart from the implant interface (8), comprising a recess (3) in a basic body (2) for forming a frame having interior contact surfaces. One of the contact surfaces is spaced apart from the opposite contact surface such that a processing space (30) is formed, into which the abutment blank (6) to be machined extends. One of the contact surfaces has at least one retaining receptacle (5), which preferably is a tapped blind hole, and which corresponds to the retainer segment (7), preferably in a friction-locking manner, such that the retainer segment (7) of the abutment blank (6) is retained in the retaining receptacle (5) in a rotationally secure manner and is oriented in a predetermined position.
