Document Type and Number:
WIPO Patent Application WO/2012/136803
Kind Code:
A1
Abstract:
The invention relates to a method for producing individual trays for positioning brackets. However, the known aids and methods all have disadvantages. Thus, the aim of the invention is to specify a method by means of which a tray for placing brackets can be created in a simple manner, which tray allows brackets to be placed quickly and with high accuracy. For this purpose, keeping a large working area free is advantageous. Easy detachment of the trays from glued-on brackets should be ensured, and the brackets should nevertheless be adequately retained in the tray. Said aim is achieved by a method for producing individual trays (13) for positioning brackets, comprising the following steps: a) producing a real model (5), wherein the at least one model is a reproduction of at least sections of at least two tooth crowns of teeth in a jaw and contains bracket reproductions or brackets associated with the reproductions of the tooth crowns; b) producing at least two trays (13) by producing at least one impression of the real model (5), characterized in that the trays (13) each comprise an impression of only at least one tooth crown part (6) of the at least two tooth crowns and only at least one bracket part (8) of the at least two bracket reproductions or brackets, wherein the at least one bracket part (8), viewed from the occlusal surface of the associated tooth crown, extends vertically to at most the end of the wire guide (9) and/or to the end of the first undercut of the bracket and/or bracket reproduction, which is arranged after the upper wing (10) in the view from the occlusal surface.
