Abstract: The present invention relates to a dental prosthesis forming block (10) for producing a dental prosthesis (50). The forming block having a pin (20) with a self-tapping outer thread, which is arranged on a first surface (11) of the dental prosthesis forming block (10). The invention further relates to a method for producing a dental prosthesis (50). In this method the dental prosthesis block (10) is provided and the dental prosthesis (50) is produced by removing material from the dental prosthesis forming block (10) by a CAD/CAM method, such that the pin (20) forms part of the finished dental prosthesis (50).

Abstract: A method, system and computer readable storage media for segmenting individual intra-oral measurements and registering said individual intraoral measurements to eliminate or reduce registration errors. An operator may use a dental camera to scan teeth and a trained deep neural network may automatically detect portions of the input images that can cause registration errors and reduce or eliminate the effect of these sources of registration errors.

Abstract: The invention relates to a method for constructing tooth surfaces of a dental prosthesis and for producing dental restorations, starting from a 3D data record of an upper mandible layout and a 3D data record of a lower mandible layout, each layout comprising a number of teeth arranged in each mandibular arch and the teeth of the upper mandible layout and the teeth of the lower mandible layout at intercuspation making contact with each other at multiple contact points. The contact surfaces are selected by approximation. Relevant surface pairs lying opposite one another are identified and are incorporated by an optimization algorithm into local minimum distances, taking into consideration surfaces that can slide past one another. This allows the desired contact points to be produced. Surfaces that have not been selected are not considered in the production of the points of contact.

Abstract: The present invention relates to a computer program and to a method for controlling the computer program, wherein a control signal is sent to the computer program when an optical marker, in particular a two-dimensional barcode (2a, 2b, 2c), is detected by an intraoral scanner (1), which signal switches the computer program to a predefined state. A device for controlling the computer program comprises a support (3) on which at least one optical marker is arranged. The optical marker has an inscription (21a, 21b, 21c) which indicates a state of the computer program to which the computer program can be switched by detection of the optical marker by the intraoral scanner (1).

Abstract: The invention relates to a method for the virtual post-processing of a first virtual three-dimensional dental model (14) of a dental prosthesis (28), said model having been created during the planning of the prosthesis (28). The first virtual dental model (14) is processed virtually after the planning stage in an additional method step (18, 31) by adapting at least one three-dimensional aesthetic surface structure (17) already in existence to the first dental model (14) by means of a virtual tool (10) with the aid of a computer (4) and a display device (6) and by subsequently inserting said structure into the first dental model (14). The aesthetic surface structure (17) has a predetermined form, size and/or a predetermined impression depth (41), and a tooth surface (19) of the dental model (14) is at least partially replaced by the adapted aesthetic surface structure (15, 17).

Abstract: Method for visualizing a tooth situation. The invention relates to a method for visualizing a tooth situation, wherein an image of the face of a patient is recorded and stored as a facial data record (1), feature points (3) within the facial data record (1) are automatically recognized by means of a facial recognition method, a mouth area (4) located between the lips is recognized automatically on the basis of the feature points (3), a position of the face in the facial data record (1) and a three-dimensional direction (5) of an orientation of the face in the facial data record (1) is automatically recognized on the basis of the feature points (3), a virtual tooth data record (2) of the tooth situation is oriented according to the three-dimensional direction (5) of the orientation of the face and is positioned according to the position of the face with respect to the facial data record (1), the mouth area within the facial data record (1) is partially overlaid and/or overlaid and/or replaced by the tooth data record (2), and the result is displayed as a visualization data record.

Abstract: A method, system and computer readable storage media for defects in images during three-dimensional measurement of teeth. An operator may use a dental camera to scan teeth and a trained deep neural network may automatically detect portions of the input images having defects and generate output information regarding those defects for corrective measures to be taken.
