Abstract: A scanning system for carrying out 3D scanning of dental models in a scanning direction V including a holding device for a whole jaw model which spans an occlusal plane E over a line-shaped mandibular arch, a base, a swivel bearing on a swivel axis normal to the scanning direction V and a stage mounted for rotation on the swivel bearing relatively to the base, on which the dental model to be scanned can be mounted. The stage can be rotated through an angular range ? of at least 150° about the swivel axis, and the whole jaw model can be mounted such that said occlusal plane E is aligned parallel to said scanning direction V. An evaluation unit receives data from a detector to generate a 3D data set.

Abstract: The invention relates to a scanning system for carrying out a 3D scan of a tooth model, comprising an imaging device and a positioning system in the form of a sliding panel which can be positioned and has first locking means. On the locking panel there are provided second locking means which interact with the first locking means such that the sliding panel can assume one of several specified positions relative to the locking panel and locks in the selected position. The invention also relates to a sliding panel for scanning dental models which has means for mounting the dental model and stands on projections disposed on its underside.

Abstract: A scanning system 1 for carrying out 3D scanning of dental models 2 in a scanning direction V, comprising a holding device 3 for a whole jaw model 2, wherein the whole jaw model 2 spans an occlusal plane E over a line-shaped mandibular arch 2.2, further comprising a base 3.1, a swivel bearing 3.3 on a swivel axis 3.4 normal to the scanning direction V and a stage 3.2 mounted for rotation on the swivel bearing 3.3 relatively to said base 3.1, on which the dental model to be scanned 2 can be mounted, wherein said stage 3.2 is mounted for rotation relatively to said base 3.1 through an angular range ? of at least 150° about said swivel axis 3.4, and the whole jaw model 2 can be mounted such that said occlusal plane E is aligned parallel to said scanning direction V, and that a axis of rotation 2.1 of said whole jaw model 2 is coaxial with the swivel axis 3.4 of said swivel bearing 3.3 and is normal to said occlusal plane E.

The sliding panel has means for mounting a dental model and stands on projections disposed on its underside. A 3D scan of a tooth model is provided by creating a first image of the object to be scanned at a precisely defined locked position, moving the sliding panel to at least one further precisely defined locked position and creating another image at each such position, and creating a 3D data set by evaluating the images produced at least two different, precisely defined positions.

Abstract: A device for operation by means of a hand-held dental instrument, in which a function of the instrument is triggered by a user by means of a triggering device, in which the device comprises a delay circuit which causes a time delay between triggering and activation of the function. In a method of operating a hand-held dental instrument, in which a function of the instrument is triggered by a user by means of a triggering device, triggering actuates a delay circuit which activates the desired function following a time delay.
