Embodiment Construction

[0053] Utilize the method according to the invention to manufacture dentures, said dentures being made in figure 1 A tooth 10 shown schematically in FIG. 2 is composed of a denture base 12 also shown schematically.

[0054] To accommodate the teeth, the denture bases each have an indentation opening 14 in which the gingival region 16 of the tooth 10 is respectively accommodated. Each tooth has, in a manner known per se, a substantially planar, slightly concavely shaped base surface 18 and the inlay opening 14 here is correspondingly shaped.

[0055] The transition between the tooth 10 and the denture base 12 is commonly referred to as the gingival margin or gingival margin 20 . The gingival margin is present both on the vestibular side 22 and on the oral side 24 . From the perspective of the vestibule, the gingival margins form a chain-like line in a known manner and form a distinct red / white transition in the patient's oral cavity, especially in the region of the incisors. ...

Abstract

The invention relates to a method for producing a denture or partial denture based on digitized data using a plurality of teeth (10) and a denture base (12) to be produced, characterized in that, in addition to the teeth (10) and the denture base ( 12) Outside the areas where the teeth (10) and the denture base (12) fit and / or are spliced ​​or connected to each other, the teeth (10) and / or generated teeth (10) made by generative or subtractive methods have a margin The denture base (12) is produced in a conventional or subtractive manner, and then the tooth (10) and / or the denture base (12) is machined to, in particular is milled to the desired prototype size.

Description

technical field [0001] The invention relates to a method for producing a denture or partial denture and to a denture. Background technique [0002] For the production of dentures or partial dentures, it is known to mill dentures with denture bases made of plastic parts. This is done in a known manner, for example based on the "Digital Denture" method, such as is basically known from EP 1832 245 B1. [0003] Disadvantageously, the gingival margin is not reproduced 100% and has two superimposed planes. A mathematically rigid line must be met here. [0004] Here, the denture base is usually milled from plastic material, and the inlay openings are also milled at the same time. [0005] The teeth themselves can likewise be milled and here be produced from any suitable material, such as, for example, composite material or ceramic. Alternatively, already finished teeth can also be used; in this case the inlay opening is adapted to the base shape of the tooth. [0006] From EP ...
