    Abstract: The invention relates to a method for performing an optical three-dimensional recording by using a hand-held dental camera, wherein the camera automatically records a plurality of individual optical recordings in succession at a defined frequency during the measurement, wherein the individual three-dimensional optical recordings are combined by means of registration into an overall recording of a dental object to be measured. Before the measurement is performed, a three-dimensional standard jaw model is displayed by means of a display device, wherein a first control point on the standard jaw model is displayed by means of the display device. The hand-held dental camera is then positioned in relation to the object to be recorded in such a way that the camera points at the first control point (10) of the standard jaw model and records a corresponding recording region of the dental object.

    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 method for constructing tooth surfaces of a dental prosthesis and for producing dental restorations, starting from a 3D data record of an upper mandible layout and a 3D data record of a lower mandible layout, each layout comprising a number of teeth arranged in each mandibular arch and the teeth of the upper mandible layout and the teeth of the lower mandible layout at intercuspation making contact with each other at multiple contact points. The contact surfaces are selected by approximation. Relevant surface pairs lying opposite one another are identified and are incorporated by an optimization algorithm into local minimum distances, taking into consideration surfaces that can slide past one another. This allows the desired contact points to be produced. Surfaces that have not been selected are not considered in the production of the points

    Abstract: The invention relates to a method and a calibration device for calibrating a dental camera (1), which is based on a fringe projection method for optically measuring a dental object (10) in three dimensions, comprising a projection grid (2) for generating a projection pattern (3) that consists of a plurality of fringes (5), and an optical system (4) that projects the generated projection pattern (3) onto the object (10) to be measured. In a first step, a reference surface (74) with known dimensions is measured by the dental camera (1) using the fringe projection method. Actual coordinates (33, 36) of a plurality of measurement points (11) are determined on the reference surface (74), and the determined actual coordinates (33, 36) are compared to target coordinates (34) of the measurement points (11) on the reference surface (74). In the following method step, proceeding from the deviations (35, 37) between the actual coordinates (33, 36) and the target coordinates (34), a plurality of compensation values (40, 50, 51, 52, 53) are calculated for the individual fringes (5) of the projection pattern (3).
