Abstract: The invention relates to a method for producing a dental splint, in particular for the treatment of craniomandibular dysfunction or for the correction of tooth misalignment, comprising a flat body made of plastics, composite and/or elastomer and having a lower face that is provided with a shape configuration according to at least portions of the dental surface profile of a patient's lower jaw, and further having an upper face that is provided with a shape configuration according to at least portions of the dental surface profile of the patient's upper jaw, the shape configuration being laterally and/or frontally-dorsally and/or vertically offset by a defined amount on the upper face relative to a position relation of optimum occlusion with respect to the shape configuration on the lower face.

Abstract: Apparatus for detecting motions of a lower jaw relative to the upper jaw of a vertebrate, comprising a first holder (30) to be fixed to the head of a vertebrate with a fixed assignment relative to the upper jaw for accommodating transmitter or receiver units of a position determining system (1) for the detection of motion, a second holder (40A) to be fixed to the lower jaw on the left side for accommodating corresponding left-sided receiver and transmitter units of the position determining system, a third holder (40B) to be fixed to the lower jaw on the right side for accommodating corresponding right-sided receiver and transmitter units of the position determining system, and a first evaluation unit (13) for processing signals from the receiver units so as to generate a differentiated dynamic image of the motions of the left and right sides of the lower jaw from relative positional changes of the transmitter units (11) which are associated with the motions of the lower jaw and are detected by the receiver un

Abstract: The aim of the invention is the improvement of an arrangement for the imaging of surface structures of three-dimensional objects, comprising a device for the optical recording of the surface of at least a partial region of the three-dimensional object from different positions, such that the imaging of the object can be carried out with comparatively little complexity with high reproducible accuracy. According to the invention, the arrangement thus comprises a selection circuit (9), for the selection of a first image section (10) and a subsequent image module (11), in which at least one further image section (12) is digitally recorded.

Abstract: An arrangement for the detection of surface contours of objects, especially in the field of dentistry, for generating a virtual 3D model, having an energy source, whose energy output is directed onto the surface of the object in order to deliver energy into the object. A sensor is provided on the side of the object away from the energy source, to detect the intensity of the energy emerging from the object. The energy absorbed in the object and determined in an energy difference module is coordinated with the layer thickness of the object, in order to image the respective surface contour by way of the layer thickness, as height information related to the surface of the incidence of energy into the object.

Abstract: A method and apparatus are disclosed for the 3-dimensional analysis of movement of tooth surfaces of the maxilla (MX) in relation to the mandible (MN), comprising a measurement system for determining the movement of two solid bodies in all degrees of freedom by means of electronic measurement sensors. A measurement MX-sensor is mounted with respect to the maxilla and a measurement MN-sensor is mounted with respect to the mandible, and the positions of the measurement sensors are recorded continuously during the performance of mandible movements.

Abstract: The invention relates to a device and a method for manufacturing a dental prosthesis with which and in which the data records for fabricated teeth are fitted into a virtual model of the oral situation. It is possible to subsequently directly manufacture the denture base or to insert the fabricated teeth in the model.
