    Abstract: A 3D printer comprising a resin vat, a component carrier, a transport box for depositing the component carrier, a transport device for removing the component carrier from the transport box and transporting it into the resin vat, and for moving the component carrier downward and upward in the resin vat The transport device has translatory axes in the vertical and horizontal directions, each of which can be driven independently by a motor, the transport device having a locking device that detachably connects the component carrier. The locking device, during the downward movement along the vertical translatory axis, reaches a specific position (P) by the drive of the respective motor, at which a stop located on the vertical translatory axis sets a coupling element in motion. A spring-loaded locking pin arranged in contact with the coupling element is immersed in a bayonet opening of the component carrier by the movement. The immersed locking pin can be brought into a locking position in the bayonet opening via the horizontal translatory axis.

    Abstract: Systems, apparatuses, and methods are provided enabling real-time collaboration with a graphical rendering program. A server computer executes a graphical rendering program that determines an application state that defines a visual object. Rendering data is generated for one or more views of the visual object based on the application state. The rendering data is transmitted to client computer devices connected to the server such that the client computer devices can display the views of the visual object. As the application state defining the visual object is determined on the server computer, displays of the visual object on all client computer devices can be updated in real-time.

    Abstract: The invention relates to a rotor (1) having a turbine wheel (3) driven by propellant (TG) in a turbine housing (2), a dental preparation instrument (20) having such a rotor (1) and a method (100) for operating such a preparation instrument (20), wherein at least one part of the propellant (TG) flows back to the gas outlet opening (51) in an inner wall (21) radially orbiting the turbine wheel (3) through a return flow channel (6) after impinging on at least one of the drive blades (31) of the turbine wheel (3) counter to the direction of rotation (DR) of the turbine wheel (3), the inner wall (21) in the segment of a circle (KS) comprises at least one return flow channel (6) extending at least from the gas inlet opening (41) as far as the gas outlet opening (51), which allows at least one part of the propellant (TG) to flow back to the gas outlet opening (51) through the return flow channel (6) after impinging on at least one of the drive blades (31) counter to the direction of rotation (DR) of the turbine wheel (3), wherein, in axial direction (AR), the turbine housing (2) has at least one cross-sectional extension (8) of a surface between drive blades (31) and inner wall (21) as far as the return flow channel (6).

    Abstract: Improving a medical scan of a head anatomy of a patient by: providing a number of scan datasets related to the head anatomy; providing intraoral data related to one or more intraoral features of the patient; determining, using the intraoral data, those parts of the scan datasets during acquisition of which a movement related to the intraoral features is detected; constructing and/or correcting the medical scan, from the scan datasets, in response to the determination. The present teachings also relate to a method of improving a CT scan, a system, a device, and a storage medium.

    Abstract: The present invention relates to an intraoral X-ray system comprising: an intraoral X-ray device equipped with an automatic exposure control (AEC) functionality and connectable to a cloud and a computer, characterized in that at least one intraoral X-ray sensor is connectable to the intraoral X-ray device, and the intraoral X-ray device comprises a functional switch which, in an initial identification process, recognizes the sensor type of the at least one connected intraoral X-ray sensor, and activates an associated mode (M; M′; M″), wherein the intraoral X-ray system comprises one or more of the following modes (M; M′; M″): a mode (M″) for intraoral X-ray sensor side detection of an exposure level, a mode (M′) for intraoral X-ray device, computer or cloud side detection of an exposure level, a mode (M) without detection of an exposure level.

    Abstract: A dental turbine driven by pressurized air comprises a head housing (1) with a turbine chamber (2) and a rotor shaft (3) mounted using an anti-friction bearing (8a) with a non-rotatably mounted turbine wheel (13). The outer race (10a) of the anti-friction bearing (8a) extends into the turbine chamber (2) in axial direction. The turbine wheel (13) comprises an annular web (16a) that is arranged concentrically to the outer race (10a) of the anti-friction bearing (8a) and, together with the outer race (10a), forms a gap seal (17a). This gap seal (17a) extends in axial direction between outer race (10a) and annular web (16a) and prevents the sucking-in of liquids and dirt particles into the turbine chamber (2) during inertial rotation of the turbine wheel (13).
