Embodiment Construction

[0058] exist figure 1 The blank 10 shown in is substantially disc-shaped. figure 1 The upper-middle area is defined for realizing the dental arch 11, and the lower side of the dental arch is defined by figure 1 visible. The base surfaces 13 of the individual teeth of the dental arch 11 can be seen.

[0059] The blank 10 consists of a disc of tooth-coloured material and a disc of flesh-coloured material, said materials being joined to each other by bonding or in any suitable manner. In this regard, by image 3 The arrangement of these materials can be seen better.

[0060] An interface 16 with a wave-like course extends between these materials. The movement mimics the human gingival margin.

[0061] Therefore, if figure 1 As shown schematically in , valleys 22 and peaks 24 alternate with each other.

[0062] The valleys 22 corresponding to the troughs are defined for accommodating the teeth, while the peaks 24 corresponding to the ribs later form interdental spaces.

Abstract

A dental prosthesis is provided, manufactured from a monobloc or multibloc prosthesis blank (10), which is composed of a gum-colored material (14) and a tooth-colored material (12), which materials (12, 14) are bonded to each other by bonding, polymerization and / or one-piece manufacture. The boundary surface (16) between the materials is wave-shaped comprising alternating grooves (22) and ribs (24) in the course of the dental arch, and radial in an oral-vestibular direction in the region of the anterior teeth (33) to be created. The boundary surface (16), at least in the region of the molars (26) again as viewed in the oral vestibular direction has parallel grooves (22) and ribs (24) forming troughs and crests of the waveform, or grooves (22) and ribs (24) such that they extend in deviation from parallel by at most 10 degrees, in particular at most 5 degrees, at least in the region of the molars (26).

Description

technical field [0001] The invention relates to a prosthesis according to the preamble of claim 1 . Background technique [0002] Dentures, but also teeth, consisting of several layers have been known for a long time. [0003] Examples of this are the solutions known from WO 90 / 13268 A1 and WO 91 / 07141 A1. [0004] Based on these rather old solutions, multi-layered plastic elements have also recently been proposed with the aid of CAD / CAM technology, which are used in the manufacture of teeth and for the manufacture of dentures providing teeth and denture bases to provide a manufactured finish dentures. Due to the different requirements for the various materials, that is to say, due to the different requirements for the flesh-colored denture base material on the one hand and the tooth-colored tooth material on the other hand, although it has already become known in other respects, this proposal is still It is not possible, and it is not possible to manufacture both teeth a...
