    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.

    IPC: A61C17/02

    Abstract: The present invention provides a treatment apparatus (1) for treating peri-implantitis. Treatment apparatus (1) is characterized by comprising: An application tip (2) that is adapted for insertion into the sub-gingival region between the screw fixture of a dental implant and the surrounding gingiva and/or bone, wherein the length of the application tip (2) is at least equal to the depth of the peri-implant pocket to be treated, and wherein the application tip (2) comprises one or more nozzles (3) for jetting pressurized sterile fluid (4) for removing the bacterial biofilms from the outer surface of the screw fixture of the dental implant in vivo; a handpiece (5) for holding and guiding the application tip (2); and a supply unit (6) for supplying pressurized sterile fluid (4) to the application tip (2).

    Abstract: The invention relates to a device and a method for generating a panoramic layer image (1, 2) of an object (3) to be imaged, by employing a 2D panoramic X-ray device, wherein the object is imaged by projecting X-rays (6) generated by an X-ray source (7) through the object (3) in a projection direction (8) and recording said X-rays (6) with an X-ray detector (9), wherein several 2D X-ray projection images are continuously recorded from various imaging directions while the X-ray source (7) and the X-ray detector (9) move around the object (3), wherein at least one panoramic layer image (1, 2) is calculated from the recorded 2D X-ray projection images by means of a reconstruction method. The panoramic layer image (2) is calculated by selecting and employing at least one partial area (50, 52, 55, 57, 65) from at least two 2D X-ray projection images (51) in relation to an active sensor area (73).

    Abstract: The present invention relates to an apparatus (20) for real-time visualizing a movement of a lower jaw (12) versus an upper jaw (14) in a craniomaxillofacial area (16) of a patient (18) in dental diagnostics, comprising: an input interface (32) for receiving a two-dimensional image signal (26) of the craniomaxillofacial area of the patient from a camera (40) and a three-dimensional jaw model (28) of the craniomaxillofacial area of the patient being precalculated based on volume data; a registration unit (34) for registering the three-dimensional jaw model with the two-dimensional image signal in a first jaw position of the lower jaw versus the upper jaw and in a second jaw position of the lower jaw versus the upper jaw; an imaging unit (36) for generating a two-dimensional depth-view (30) of the craniomaxillofacial area from the three-dimensional jaw model based on the conducted registrations and the two-dimensional image signal, said two-dimensional depth-view including a structure underlying an image area of the two-dimensional image signal; and an output interface (38) for outputting the two-dimensional depth-view. The present invention further relates to a system (10) and method for real-time visualizing a movement of a lower jaw (12) versus an upper jaw (14) in a craniomaxillofacial area (16) of a patient (18) in dental diagnostics.

    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 invention relates to a method for producing a two-dimensional whole image of a recording region captured by means of a plurality of individual images, each having its own viewing direction and its own distance, wherein a spatial orientation of a main image plane of each individual image relative to a main image plane of the respective further individual image is determined on the basis of an overlap of the respectively captured subregions, and at least a plurality of the individual images are combined in accordance with the spatial orientations to form the whole image. The whole image area is the surface of a torus.
