Abstract: The invention relates to a method for producing a guided bite splint for a supporting jaw comprising at least one guide for an opposing jaw. A 3D model of an upper jaw and/or a 3D model of a lower jaw are available, wherein the 3D models of the upper jaw and the lower jaw are arranged relative to one another in an occlusal position and integrated into a virtual articulator model which simulates an articulation movement of the lower jaw relative to the upper jaw, wherein a 3D model of the bite splint is constructed using the 3D model of the upper jaw and/or the 3D model of the lower jaw, wherein the at least one guide for the opposing jaw is constructed automatically on the 3D model of the bite splint with the aid of a computer.

Abstract: The invention relates to a method for producing an individualized dental impression tray and to one such impression tray, wherein a digital impression tray model of an individualized impression tray is created on the basis of a digital jaw model, the impression tray model has a carrier with at least one inner surface which at least partially corresponds to a negative form of the jaw model, at least one surface subregion on the inner surface is marked by hand or automatically detected, a retaining structure is arranged above and/or below the surface subregion, the impression tray model is stored with the retaining structure as a production template, and the impression tray is produced by machining according to the production template. The retaining structure has a first surface which extends substantially parallel to the surface subregion or substantially in line with the surface subregion and has at least one recess running through it, wherein a depression adjoins each recess of the first surface, the depression extends from the recess in the direction of the carrier and/or into the carrier, and each depression has at least one undercut.

Abstract: The invention relates to a method for computer-aided planning of a repair or adjustment of a dental partial prosthesis with the following method steps: generation of a first digital 3D model of a jaw with the partial prosthesis positioned on the jaw as a prosthesis reference model (M1), generation of a second digital 3D model of the jaw, without the partial prosthesis, as a jaw model (M2), determination of a positional relationship of the prosthesis reference model (M1) to the jaw model (M2), generation of a digital prosthesis model (P) by subtracting the jaw model (M2) from the prosthesis reference model (M2) while taking the positional relationship into account, automatic identification and/or identification carried out by a user of holding and/or support elements (3) in the prosthesis model (P), calculation of an insertion axis (4) of the partial prosthesis on the basis of the prosthesis model (P), calculation of undercut depths, resulting from the insertion axis (4), of the holding and/or support elements (3) in the prosthesis model (P), display of the insertion axis (4) and the undercut depths in the presentation of the jaw model (M2).

Abstract: The invention relates to a method for generating a digital model (6) of a dental replacement part, formed by a dental prosthesis and a prosthesis base having a rear protection plate, and for producing a dental replacement part of this type, wherein, in a digital model (1) of a jawbone to be provided and a digital dental prosthesis model (2) positioned therein, an interface (3) is automatically and/or manually marked in the region of the dental prosthesis model (2), a rear protection plate model (4) is formed by the interface (3), an abutting surface (1′) of the digital jawbone model (1) and a region of a surface (2′) of the dental prosthesis model (2) joining the surface (1′) and the interface (3), a revised dental prosthesis model (5) is formed from the digital dental prosthesis model (2) by adopting the interface (3) as a surface, and the digital model (6) of the dental replacement part is created from the rear protection plate model (4) and the revised dental prosthesis model (5).
