Abstract: The invention relates to a dental x-ray imaging system for producing intraoral x-ray images, in particular of dental patient tissue, with the aid of an intraoral x-ray sensor, which can be placed in the oral cavity in the beam path of an x-ray emitter positioned outside the oral cavity, wherein the x-ray imaging system is configured to record two or more temporally sequential individual x-ray images and to create an overall x-ray image from said individual images in such a way that the results of the exposures of the x-ray images are combined and a motion occurring between and/or during the sequential individual x-ray images is compensated.

Abstract: The present invention relates to methods for curing polymeric dental appliances comprised of partially cured photopolymerizable components, especially for additively manufactured denture base and artificial tooth components utilized in the production of full and partial dental prostheses. In particular, the invention relates to methods of utilizing a curing apparatus having one or more controllable heating sources and one or more controllable LED light sources to achieve specific preheating and light curing conditions for more effectively converting partially cured photopolymerizable components from a partially cured state to a final cured state.

Abstract: The present invention proposes a method for producing a 2D panoramic image of an oral cavity comprising the steps: A) provision of a plurality of projection images acquired during an at least partial revolution of a recording unit comprising a radiation source and an electronic image sensor about the oral cavity in a given position; B) calculation of an image including at least one anatomical feature from the plurality of projection images using a calculation rule with reconstruction parameters; C) provision of a model of the at least one anatomical feature, which describes the at least one anatomical feature in a target position in an image; D) identification of the at least one anatomical feature in the calculated image; E) determination of a deviation between an actual position of the at least one identified anatomical feature in the calculated image and the target position of the at least one anatomical feature in the model by applying a metric; F) variation of at least one of the reconstruction parameters and recalculation of at least one part of the image that shows the at least one anatomical feature using the calculation rule and the at least partially varied reconstruction parameters or variation of a pixel transformation and application of the pixel transformation to at least one part of the calculated image that shows the at least one anatomical feature, so that at least this part of the image is recalculated; G) derivation of the 2D panoramic image from the recalculated image; and H) outputting the 2D panoramic image.

Abstract: A method for generating a panoramic image with reduced overlapping of neighboring teeth, including: acquiring 2D x-ray images respectively at a different radiographic directions by a rotating an x-ray source and an x-ray detector around the jaw of a patient. It includes a step of identifying one or more regions each including at least one pair of overlapping neighboring teeth in the 2D x-ray images and/or in temporary panoramic images reconstructed from the 2D x-ray images for which an optimal radiographic directions are determined, among the corresponding radiographic directions, which reduces the overlap in the panoramic image to be reconstructed. It includes determining one or more optimal radiographic directions respectively among the corresponding radiographic directions of the 2D x-ray images for which one or more regions each including at least one pair of overlapping neighboring teeth has been identified, to reduce the overlaps in the panoramic image to be reconstructed.

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).
