  • Publication number: 20230293275
    Abstract: A method for defining different layer elements of an artificial tooth element, having the following steps: defining an interface between an inner core element and an outer layer element at least partially surrounding the inner core element; selecting an additional layer element from a provided selection list containing a plurality of additional layer elements; and automatically arranging the at least one selected additional layer element in spatially defined relation to the core element and/or the outer layer element.

  • Publication number: 20220409348
    Abstract: A method for defining at least one boundary surface inside an artificial tooth element, the method comprising the steps of: aligning the tooth element with a coordinate system which preferably relates to anatomically defined directional terms; defining a first boundary curve on the tooth surface; determining a tooth surface located incisally/occlusally with respect to the first boundary curve; and moving this tooth surface inwards in the direction of the surface normal by different amounts in order to produce the at least one boundary surface, in particular the first boundary surface, wherein the different amounts of the movement involve variable design parameters.

  • Patent number: 11154385
    Abstract: Artificial teeth are inserted in a denture base in order to produce a denture. The artificial teeth used according to the invention have an outer part, which is visible in the inserted state. An inner part is arranged in the denture base in the inserted state. A virtual data record of the artificial tooth, which corresponds to the outer side of the tooth, helps to define a virtual gum line in a region of the inner part of the tooth, which is undercut-free. In order to produce a denture base, cavities are created in the denture base. In order to be able to create the cavities with the help of automatic production methods such as CAD/CAM methods, the artificial teeth are virtually subtracted from a virtual denture base such that a cavity edge is defined, which corresponds to the virtual gum line.

  • Publication number: 20160278885
    Abstract: An implant 1 comprising an enossal area 3 and provided with a coating 2, wherein the coating 2 at least partially covers the enossal area 3, and the coating 2 facilitates the ongrowth of the implant 1 within the bone, characterized in that said coating can be removed chemically and/or mechanically under physiological condition.
