Embodiment Construction

[0065] figure 2 The steps of the embodiment of the method according to the invention shown in are detailed as follows:

[0066] - Modeling by the dentist via an intraoral scanner

[0067] - Generate digitized model data

[0068] - Optional: forward the digitized model to the laboratory

[0069] -Digital tooth creation

[0070] - Optional: digitally divide the 3D data set into red (gingiva), white (teeth (dental arch)) and / or gray (gray is used to represent the interior of the veneered bridge structure or if necessary by the implant earlier model castings in the case of body-supported partial dentures)

[0071] - Manufacture of individual elements, utilizing connecting elements where necessary

[0072] - wherein the inside of the tooth or tooth arch is produced by automated means and at least one second material is applied thereto as an outer layer by automated means (preferably by means of milling or SLA or inkjet printing the inner part of the tooth is produced (inner ...

Abstract

Summary Methods for the production of complete or partial prostheses involve, firstly A) provision of 3D data of the situation in the mouth in the edentulate or partly toothed state; B) digital designing of the denture base for lower and upper jaw each; C) digital positioning of virtual teeth with appropriate occlusion and a tooth shape selected according to aesthetic criteria, in the case of complete prostheses, D1) production of the dental arch using an automated method from the groups of layer-building and of material-removing methods; and D2) production of the denture base using an automated method from the groups of layer-building and of material-removing methods; and, in the case of partial prostheses; D1) production of the dental arch using an automated method from the groups of layer-building and of material-removing methods; and D2) production of the support structures or fastening elements using an automated method from the groups of layer-building and of material-removing methods.

Description

technical field [0001] The present invention relates to a method for the automated manufacture of dentures, in particular the manufacture of individual dentures from digitally extracted data of oral conditions via CAD / CAM and rapid manufacturing / rapid prototyping. Background technique [0002] The manufacture of complete dentures and partial dentures is carried out according to known methods. Mention is to be made, for example, of the conventional methods of powder / fluid technology, as known for a long time and described in the literature (eg EP 1 243 230 A2, US 6 881 360 B2 and "Ullmann's Encyclopedia of Industrial Chemistry Copyright 2002 by Wiley -VCH Verlag" in "Dental Materials"). [0003] Three different main material classes are generally known for the manufacture of full denture articles. They are two-component materials based on polymethylmethacrylate (PMMA) [commercial products Palapress, Paladur (Heraeus Kulzer, DE), Quick (Ivoclar, LI), (Degussa-Hüls, DE)];...
