Embodiment Construction

[0080] figure 1 A dental post or model 1 of a dental post is shown. Of particular importance here is the geometrical data of the outer contour of the post, the frame (see figure 2 ) to match the inner contour.

[0081] figure 2 A dental bracket 3 with an inner contour adapted to the outer contour of the dental post 1 is shown. The tooth frame 3 in turn has an inner contour of the dental veneer which must be defined to match its outer contour.

[0082] image 3 A first embodiment of a dental bracket 3 is shown, on top of which a model 5 of a dental veneer is positioned. The model 5 is directly generated on the dental frame 3 itself based on the three-dimensional geometric data of the dental frame 3, or is formed separately, and has an outer contour corresponding to the intended denture.

[0083] Figure 4 A second embodiment of the combination of a dental frame 3 and a model is shown. The model consists of two model parts 5a, 5b which are produced separately from the...

Abstract

The invention relates to a method (100, 200, 300) for producing a dental prosthesis (17) with a framework (3) and a veneer (15), in particular for producing a crown, a bridge, an inlay or an onlay. The invention further relates to a system (40, 50) for producing a dental prosthesis (17) with a framework (3) and a veneer (15) and to a corresponding computer program. To allow the dental prosthesis (17) to be produced in a short time and in uniform quality, irrespective of the skill of the operator, the following steps are provided: definition (110, 210, 310) of three-dimensional geometrical data of the veneer (15), provision (101) or preparation (218, 318) of the framework (3), production (120, 220, 320) of a model (5, 5a, 5b, 5c, 5d) of the veneer (15) on the basis of the three-dimensional geometrical data of the veneer (15), on the framework (3) or separately, formation (124, 224, 324) of a female impression (11) of the veneer (15) by inclusion (126, 226, 326) of the model (5, 5a, 5b, 5c, 5d) between the framework (3) and a shaping material (9), and then removal (128, 228, 328) of the model (5, 5a, 5b, 5c, 5d), and filling (130, 230, 330) of the female impression (11) with veneer material for producing the veneered dental prosthesis (17).

Description

technical field [0001] The present invention relates to a method for producing dental prosthesis comprising or comprising a framework and a veneer, in particular for producing crowns, bridges, inlays or onlays )Methods. The invention also relates to a system and a corresponding computer program for generating a denture comprising or comprising a dental framework and a dental veneer. Background technique [0002] Dentures, such as crowns, can be used to restore, replace or replicate teeth that have been damaged or destroyed. There are many different options when it comes to the material from which dentures are made. [0003] In terms of function, some or all of the teeth can be completely replaced or restored with metal dentures. However, for aesthetic reasons, it is in many cases reluctance to manufacture dentures entirely of metal. [0004] For reasons of aesthetics (translucency) and above all biocompatibility, the use of glass ceramics for the manufacture of dentures ...
