    Abstract: The invention relates to a method for validating a drilling template for producing an implant-borne tooth replacement before performing an implant drilling. The drilling template produced is placed on dental structures of a jaw area that is to be provided with the tooth replacement. A measuring element is inserted into the drill guide of the drilling template, wherein the measuring element and at least one partial region of the dental structures not covered by the drilling template is measured using an optical three-dimensional measuring method. Then the position and orientation of the measuring element in relation to the partial region of the dental structures are determined from the generated measured data of the optical measurement, wherein a virtual actual implant drilling model is created on the basis of the optical measured data using the position and orientation determined for the measuring element, and/or using the known dimensions of a drill to be used, and/or the position of a stop surface on the drilling template for the drill to be used, wherein the actual implant drilling model is compared with a planned virtual target implant drilling model from a previous implant planning with respect to its position and its orientation.

    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.
