Problems solved by technology

[0007] The disadvantage here is that with the dentures produced by means of the CAM method, an optimal esthetic result cannot be obtained without further finishing steps such as polishing and staining of the dentures
In addition, the rough surface of dentures can easily lead to the adhesion of food residues
And in the CAM method, due to the mostly layered structure, there will be undesired physical properties of the denture

Embodiment Construction

[0064] The figure shows the patient's edentulous upper jaw 1 and edentulous lower jaw 2 and shows the tongue 3 in the patient's oral cavity. A two-part denture fits over a dental arch. The foundations of the two prosthetic parts are substantially each formed by a prosthetic base plate 4 of the upper jaw 1 and the lower jaw 2 , which rests on the toothless dental arch. In the prosthetic base plate 4 there is provided a recess for the prosthetic tooth root 6 into which the prosthetic tooth root 6 fits. The denture root 6 is glued in the recess of the denture base plate 4 .

[0065] A tooth cover 8 made of hard plastic is arranged on the tooth root 6 of the denture, and the tooth cover constitutes the occlusal surface of each denture in the whole set of dentures. to this figure 1 The denture of the molars is shown. The mouthpiece 8 abuts on the upper side with its occlusal surface (chewing surface in the case of molar dentures). The desired occlusal plane 10 of the two prost...

Abstract

The invention relates to a method for producing a denture. In one embodiment, a prosthetic baseplate (4) and multiple tooth stump prostheses (6) are produced by applying a CAD model and pre-fabricated veneers (8) are affixed on the tooth stump prostheses (6), whereby the thickness values of the veneers (8) are taken into consideration during generation of the CAD model of the tooth stump prostheses (6). The invention also relates to a denture, in particular fabricated through a method of this type, in which multiple tooth stump prostheses (6) are affixed in a prosthetic baseplate (4) or are structured to be the same part as the prosthetic baseplate (4) and a veneer (8) is affixed in coronal position on at least one tooth stump prosthesis (6), preferably a veneer (8) is affixed in coronal position on each tooth stump prosthesis (8).

Description

technical field [0001] The present invention relates to a method of manufacturing a denture and a denture. Background technique [0002] Dentures are used to replace teeth in an edentulous jaw or teeth in a partially edentulous jaw and should therefore at least recreate the chewing function of the patient's mouth as well as improve the overall aesthetics of the face, especially the mouth. [0003] Currently, it is common practice to create dentures in a simulated manner. For this purpose, the teeth are created manually and individually on the wax base. The next step is to embed these wax dentures in a container with plaster, and then after the plaster hardens, the wax matrix is ​​washed away with hot water and a cavity is provided for the denture plastic material. [0004] At the same time the teeth remain in plaster. The corresponding (PMMA) plastic is injected or "plugged" into the cavity and the finished prosthetic base plate is obtained after the plastic hardens. Whe...
