Abstract: A method and device for identifying objects, especially teeth, on a digitized X-ray picture, by using image processing algorithms to localize areas containing the object by segmenting and/or edge detection, these areas being computationally linked with parameters of the X-ray unit and, optionally, with patient-heightened specific parameters. Another method and device for assigning information to objects, especially teeth, determined in a digitized X-ray picture or in a schematic representation, includes a first step detecting the digitized X-ray image for the schematic representation, a second step in which a determination of objects manually or automatically ensues in the event these objects have not yet been determined, a third step selecting the object for which additional information should be stored, retrieved or deleted, and a fourth step in which a reference that is stored is followed for a query operation to determine the information displayed by using such reference.

Abstract: A method for detecting and representing one or more objects, such as teeth, their preparations and their immediate environment, using a camera. A first recording is made wherein a still image is produced. The still image is blended into a current, mobile search image in at least one sub-area in the second step, so that both images are recognizable. In the third step, the camera is positioned in such a way that the search image overlaps the blended-in still image in at least one sub-area. The second recording process is initiated in a fourth step.

Abstract: Current position data is determined of a first machining tool in a machining space having a second machining tool, the second tool having known position data with regard to the position data of the first tool which are to be determined, the first tool and the second tool being movable toward and away from one another, the first tool to be determined in its position comes into contact with a machining surface, known in its position, of the second machining tool, the rotary speed of a drive motor for the second tool being set to a starting rotary speed which is so low that the rotary speed of the second tool is measurably reduced when the tool comes into contact.

Abstract: The invention relates to a dental x-ray device comprising a mobile support structure for a system that can be displaced to produce x-ray photographs and also comprising a fixed support structure. The mobile support structure is displaceably mounted on the fixed support structure by one or more bearings. The device is provided with adjustment elements for the displacement of the support structure parallel to the bearing surface, in addition to a drive for carrying out a rotation of the support structure about an axis that is perpendicular to the bearing surface. The bearing elements are configured in such a way that they can be displaced on the bearing surface in every direction parallel to the bearing surface and can carry out a rotation about an axis that is perpendicular to the bearing surface.

Abstract: A 3-D camera and a method for recording surface structures on an object of interest by triangulation, in particular for dental purposes. The camera provides for producing a group of light beams in order to illuminate the object of interest via a projection optical path, an image sensor for receiving light back-scattered by the object of interest via an observation optical path, and provides, in the projection optical path, for producing a pattern projected onto the object of interest. To avoid ambiguities in the event of large height differences, the camera provides for the projection optical path and/or the observation optical path for altering the triangulation angle, which is defined by the angle between the centroid beam of the projection optical path and the centroid beam of the observation optical path. The proposed process involves the taking of at least two 3-D measurements of the same object of interest with different triangulation angles.
