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

[0048] 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 Incisors 31 and 33 are shown. 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 . The incisors 31 and 33 are glued into the denture base recesses 11 respectively.

[0049] 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 inn...

Abstract

The invention relates to a dental transfer template arrangement with a transfer template and a prosthesis base, both of which are produced using the same CAD / CAM device in particular, wherein - both have a number of recesses for teeth, incisal and / or occlusal tooth regions fitting into the transfer template recesses and cervical tooth regions fitting into the prosthesis base recesses, and - each tooth is to be adhered into a prosthesis base recess. The invention is characterized in that - the transfer template (20) has an occlusal face (22) which corresponds to the occlusal plane and which is implemented as a reference for the presence of disruptive occlusal contacts such that - teeth regions (310) which protrude past said face (22) of the transfer template (20) can be polished for an even bite, and - the adhesive surface area of each tooth (31, 33, 35, 37) has a specified minimum threshold in the prosthesis base (10), in particular at least 10 mm, preferably at least 18 mm2, and particularly preferably at least 25 mm2, said threshold being stored in particular in the CAD software of the CAD / CAM device in order to produce the prosthesis base.

Description

technical field [0001] The invention relates to a dental transfer template system according to the preamble of claim 1 . 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 ar...
