Abstract: A method for the computer-aided editing of a digital 3D model (1) of a dental object using digital tools (T1, T2, T3) provides for the identification of different dental-specific regions (R1, R2, R3) of the 3D model (1) that are affected by the tool (T1, T2, T3) in different ways, for computation of the effect on the whole 3D model and for display thereof as a proposal model (2) together with the 3D model (1). The proposal model (2) is then rejected or accepted in part or in full. If it is accepted in part, at least one subregion of the 3D model (1) is selected as a region (10) and a result model (6) is formed from the 3D model (1) and the proposal model (2) by virtue of the 3D model (1) being taken as the starting point for replacing the selected region (10) or at least a central portion of the selected region (10) with a corresponding region of the proposal model (2) or approaching the latter using a strength factor (S).

Abstract: A method for producing a tooth replacement part to be secured on an implant, based on a 3D model of the tooth replacement part with a surface and with a continuous screw channel with an initial shape in the form of a cylindrical barrel, with a first and a second end, wherein a cross sectional area of the screw channel is designed to be constant and/or to increase in size towards the second end of the screw channel. A 3D model of an inlay with a jacket surface, an upper face and a lower face is generated. A part of the surface of the 3D model of the tooth replacement part that is cut out through the second end of the final shape of the screw channel is used as the upper face and the jacket surface is configured as a negative form of a part of the final shape of the screw channel that adjoins the second end.

Abstract: The invention relates to a method for the virtual secondary machining of a virtual three-dimensional gingiva model, said model having been created during the planning of an artificial gingiva. Here, the virtual gingiva model is virtually machined by at least one defined three-dimensional surface structure of the gingiva model being modified by means of a virtual tool using a computer.

Abstract: Digital design and/or fabrication of a dental prosthesis that includes a gingiva part having retention pockets and corresponding injection channels that extend from the retention pockets to an exterior of the gingiva part. The positioning of a matrix mated to a ball attachment of a dental implant is fixed in the retention pocket by injection of a curable adhesive through the injection channels and into the retention pockets. The location of the retention pockets and the injection channels may be automatically generated by a computer-aided design/computer-assisted manufacturing (CAD/CAM) system. The gingiva part including the retention pockets and injection channels can further be designed and fabricated by the CAD/CAM system.

Abstract: Preparation of a dental prosthesis that includes a gingiva part having retention holes for seating of manufactured teeth, with the retention holes being enlarged relative to the manufactured teeth. A size and geometry of each of the enlarged retention holes are determined based on a size and geometry of the corresponding manufactured tooth. Wax in the enlarged retention holes permits adjustments in positioning of the manufactured teeth, and a helper structure preserves this positioning when the wax is removed and a curable gingiva material is filled into the retention holes.
