The invention relates to a method for producing a dental prosthesis from a prosthesis base and a plurality of prosthesis teeth, characterized by the following chronological steps: The invention also relates to a dental prosthesis produced by such a method, and a set for carrying out such a method.

Method for producing a dental prosthesis

The invention relates to a scan abutment () for determination of the position of the plane of the front face () of a dental endosseous implant (), wherein the abutment () has a longish, hollow shaft () and a base () at the bottom side () of the shaft (), and the base () with at least a part of its bottom side () is attachable onto the front face () of the implant (), wherein the base () has a recess () extending from the upper side () to the lower side () of the base (), wherein the longish, hollow shaft () has from a side wall () having at least one through hole () at its outer periphery, wherein the through hole of the side wall () extends from the bottom side () of the shaft () to the upper side () of the shaft, thereby forming a planar surface () in the plane () between shaft () and base ().

Scan abutment having an enlarged scan surface

The invention relates to a scan abutment (), in particular an integrally manufactured scan abutment, for determination of the position of the front face () of a dental endosseous implant (), wherein the abutment () has a longish, hollow shaft (), and the shaft has an upper region (), a central region () and a lower region (). Moreover, the shaft () of the scan abutment with its central region () is attachable onto the front face () of the implant (), and its lower region () is insertable into the connection geometry of the implant. The longish, hollow shaft () has a side wall (). The shaft of the scan abutment has at least two to terminally extending slits () in its central region () and lower region () in the side wall (). Two, three or four slits are preferred. Preferably, the slits () end in one recess () each, such as a circular recess, in the side wall () at their upper end and extend terminally in the side wall () to the bottom side of the shaft (). Another subject matter of the invention is a kit comprising a scan abutment as well as the screw adjusted to the scan abutment or the bolt adjusted to the scan abutment.

Scan abutment for a dental implant having reduction of the fit clearance

The invention relates to a temporary dental prosthesis for determining abrasion facets, having at least one prosthetic tooth, in which at least the occlusion surface of the prosthetic tooth or at least one of the prosthetic teeth is made of a material that is abradable such that, within a maximum of 12 weeks of use as a dental prosthesis by a patient, abrasion facets are produced on the prosthetic teeth and are suitable for ascertaining the chewing movements of the jaw of the patient. The invention also relates to a method for determining the chewing movement of a set of teeth from measured abrasion facets, in which a temporary dental prosthesis made of an abradable material is inserted in a patient, and to a method for producing a final dental prosthesis.

Dental prosthesis for determining abrasion facets

The invention relates to a method for producing a dental prosthesis, wherein the dental prosthesis comprises a prosthesis base and a plurality of prosthesis teeth, wherein the method is carried out making use of a virtual three-dimensional dental prosthesis model of the physical dental prosthesis which is to be produced, and wherein the virtual three-dimensional dental prosthesis model comprises virtual prosthesis teeth and a virtual prosthesis base, with the steps:
