Problems solved by technology

[0009] If the adhesive connection of the artificial tooth on the denture base is not strong enough, there is also the risk that the tooth is not held firmly enough in the denture base 10 during chewing movements or other tooth movements in the oral cavity. cavities and may even fall out of the denture base

Embodiment Construction

[0054] exist figure 1 The dental transfer template system 100 shown in has a transfer template 20 and a (maxillary) denture base 10, wherein both the transfer template and the denture base have a plurality of notches 21 and 11 for the incisors in which figure 1 Teeth 31 and 33 are shown in . The incisal and / or occlusal regions of the teeth 31 and 33 fit into the transfer template notches 21 , while the cervical regions fit into the denture base notches 11 . Teeth 31 and 33 are bonded into denture base recesses 11 respectively.

[0055] The teeth 31 and 33 are introduced into the cavities / recesses 11 of the denture base 10 in any suitable manner by means of the transfer template 20, in that the teeth 31 and 33 are temporarily fixed to the transfer template, for example with wax, resin or other adhesives The teeth 31 and 33 are held in the transfer template 20 in the inner surface of the recess 21 of the transfer template, or by means of the deforming force of the inner surfac...

Abstract

The present invention relates to a dental transfer formwork system, the dental transfer formwork system has a transfer formwork and a denture base, the transfer formwork and the denture base are especially manufactured using the same CAD / CAM device, wherein the transfer formwork and The denture base has multiple recesses for the teeth, the incisal and / or occlusal areas of the teeth fit into the transfer template recesses, and the cervical areas of the teeth fit into the denture base recesses, the teeth respectively to be bonded to the denture In the base recess, it is characterized in that the transfer template (20) has an occlusal side (22) corresponding to the occlusal plane, said occlusal side as a reference for the presence or absence of an occlusal interference contact point realized in such a way that it protrudes beyond the transfer template (20) The tooth area (310) on the occlusal side (22) of the can be ground into a neat dentition closure, and the bonding surface of each tooth (31, 33, 35, 37) in the denture base (10) has a predetermined a minimum threshold, which in particular is at least 10 mm 2 , preferably at least 18mm 2 and particularly preferably at least 25mm 2 , said threshold value is determined in particular in the CAD software of the CAD / CAM device used to manufacture the denture base.

Description

technical field [0001] The present invention relates to a dental transfer template system. Background technique [0002] For dentures produced by CAD / CAM it is necessary that the artificial teeth are bonded to the denture base. Artificial teeth can be manufactured both conventionally (industrial) and by CAD / CAM and consist of different materials. [0003] Correct positioning of the individual teeth relative to the denture base is necessary in order to permanently bond the artificial teeth in the cavity of the denture base. Here, each tooth or each set of teeth is checked individually and manually for the correct fit and subsequently cemented. [0004] For checking, so-called transfer templates have been proposed. Such a transfer template is in particular a negative mold produced by CAD / CAM in which recesses are provided for supporting the teeth. The teeth and / or groups of teeth are temporarily supported in the recesses of the formwork and are transferred into the cavitie...
