    Abstract: The present invention relates to an intraoral X-ray sensor for use with an intraoral X-ray system having an automatic exposure control (AEC) functionality, characterized in that the intraoral X-ray sensor includes an exposure analysis unit, an imaging X-ray detector, and a communication interface, wherein a scout shot or scout video stream received from the imaging X-ray detector is analyzed by the exposure analysis unit in the intraoral X-ray sensor in order to record information on the exposure level of the scout image or video stream and to forward this information by means of the communication interface to a decision unit of the intraoral X-ray system, which is arranged externally to the intraoral X-ray sensor, and adapted for evaluation and decision of further exposures.

    Abstract: A computer-implemented method for the automatic generation of component-describing data for use in a preparation of additive/subtractive manufacturing jobs for dental components such as splints, denture bases, models, restorations such as bridges and crowns, in which for each at least one component type a specialized pre-trained neural network is used for setting surface and/or volume attributes of the dental component, in which the surface and volume attributes describe the accuracy and quality requirements of construction elements of the dental components with regard to the intended use, in which the accuracy and quality requirements comprise at least one of the following: geometric dimensional accuracy, mechanical strength, surface texture color, and the avoidance of the attachment of support elements, in which the neural network has been pre-trained by means of dental components for which the surface and/or volume attribution has already been carried out.

    Abstract: The present teachings relate to a method for assisting an intraoral scan including providing an intraoral image of a patient, and providing an extraoral image; the extraoral image being representative of the position of an extraoral scanner part. The teaches further include generating, using the intraoral image and the extraoral image, a mapping function correlating the position of the extraoral scanner part with the position of the intraoral scanner part; and computing, using the mapping function, a desired extraoral position of the extraoral scanner part; the desired extraoral position corresponding to a preferable intraoral position of the intraoral scanner part. The present teachings also relate to a system, a device, a use, data, and a storage medium.

    Abstract: The invention relates to a method for producing a panoramic tomographic image (1, 11, 60) of an object (2) to be recorded using a 2D panoramic X-ray device (3), in the course of which X-rays (4) produced by means of an X-ray source (5) irradiate the object (2) and are acquired by means of an X-ray detector (7), wherein, during a movement of the X-ray source (5) and the X-ray detector (7) around the object (2), a number of 2D X-ray projection images (30) are acquired from different acquisition directions (6). A first panoramic tomographic image (1) is calculated from the acquired 2D X-ray projection images (30) using a reconstruction method, wherein the acquired 2D X-ray projection images (30) are modified using a modification method, wherein, from the modified 2D X-ray projection images (40, 50) and using the reconstruction method, a second panoramic tomographic image (11) is calculated with a higher weighting of artifacts (20) relative to anatomical structures (17, 18, 19), wherein a third panoramic tomographic image (60) with significantly reduced artifacts is calculated.
