Embodiment Construction

[0049] figure 1 A schematic sectional view of a dental restoration 10 according to the invention is shown, the dental arch 12 consisting of a tooth material 14 and the denture base 16 consisting of a base material 18 . The base material and the tooth material are cohesively bonded to each other at the boundary surface 20 .

[0050]The dental restoration 10 is produced, for example, from a disc-shaped blank. In the blank, the boundary surface 20 extends in a wave-like manner, with waves extending along the periphery. For the design of dental restorations and blanks reference is made in its entirety to EP 3 064170 A2.

[0051] The waves of the boundary surface 20 alternately have troughs and crests viewed along its periphery corresponding to the gingival margin and preferably extend in the form of a catenary, such as figure 2 as shown. Viewed in the vestibular-oral direction, the waves run radially, that is to say in the direction of the vestibule, ie expand radially outwar...

Abstract

The invention relates to a method for producing a dental restoration from a blank, which consists in part of a base material and in part of a dental material, with boundary surfaces between the materials, which are configured in the form of a waveform, the peaks and valleys of which alternate with one another along the periphery of the blank, using a CAD / CAM device. The apex of each crest has a substantially radial trend relative to the blank. The CAD / CAM device determines the position of a holder, in particular an outer sleeve, a ferrule of a connecting rod or an abutment, for fixing the prosthesis to the alveolar process of the patient in the prosthesis such that the holder passes through the boundary surface. The holder is secured by adhesion, threaded connection, or aggregation.

Description

technical field [0001] The invention relates to a method for producing a dental restoration from a blank according to the preamble of claim 1 , a blank for producing a dental restoration according to the preamble of claim 3 And a dental restoration according to claim 8. Background technique [0002] When producing a dental restoration, care is usually taken to select the shape of the dental restoration in such a way that it presents as little discomfort as possible for the user. Patients should be able to speak, swallow and chew as if they had their natural teeth. [0003] For such dental restorations, on the one hand good material compatibility and, on the other hand, a light profile of the restoration is desired. [0004] In order to ensure a more reliable fixation of the tooth in the dental restoration, the tooth is usually cemented, but alternatively it can also be introduced by injection moulding. [0005] A solution related to this is known from DE 837 288 B1. [0...
