  • Patent number: 9918812
    Abstract: The invention relates to a tooth made of ceramics, a composite or plastic, which is produced in a mold, said tooth having a basal surface (16) that comprises a trough (18). The especially elliptical or circular trough (18) is adapted to the basal surface (16) and has a trough edge (22, 24) which extends at least partially in an angle of more than 45 degrees, in particular more than 60 degrees or 70 degrees, with respect to the adjacent basal surface (16).

  • Publication number: 20160157972
    Abstract: The invention relates to a dental transfer template arrangement, with a transfer template and a prosthesis base which in particular are both produced by the same CAD/CAM device, wherein both have a large number of recesses for teeth, wherein incisor and/or occlusal areas fit into the recesses of the transfer template and cervical areas of teeth fit into the recesses of the prosthesis base, wherein the teeth are each to be adhesively bonded in the recesses of the prosthesis base, characterized in that a bite barrier (18) of the transfer template (20), which barrier prevents closure of rows of teeth, is provided in the occlusal plane, the thickness of which barrier measures in particular about 2 to 8 mm, and in that, starting from the bite barrier (18), the tooth recesses (21) are open in mutually opposite directions corresponding to upper jaw and lower jaw, in that teeth are held in the recesses (21) of the transfer template (20) and, in particular, the transfer template (20) for the teeth (33, 35) can be used

  • Publication number: 20150216638
    Abstract: The invention relates to a denture, made of teeth, in particular prefabricated teeth, and of a denture base made of a gingival material, comprising cavities for teeth in which cavities for the teeth are mounted, in particular attached by bonding, characterized in that the denture base (12) is produced by a CAD/CAM process forming the cavities (20) for the teeth (14), and in that cervical areas (40a) of the teeth (14) extending through the basal surface (16, 18) of the denture base (12) are removed, in particular abraded or milled.

  • Patent number: 8222315
    Abstract: The present invention relates to a process for the preparation of composites which can be used in the dental field, in which a) mono-or polyfunctional monomers dissolved in a solvent are polymerized to give a polymer gel thoroughly swollen with the solvent, b) the polymer gel produced is subjected to preliminary size reduction, c) a reactive gel is subsequently prepared by the polymer gel, subjected to preliminary size reduction, incorporating a polymerizable monomer or a mixture of polymerizable monomers in the polymer gel while simultaneously removing the solvent, and d) a dental composite is prepared from the reactive gel thus obtained.
