Abstract: The invention relates to a method for producing tooth prosthesis parts comprising an implant for inserting into the jaw and a prosthesis for securing to an implant by means of a connecting surface (52). A first measuring data set of a 3D X-ray image is prepared in the region of the prosthesis which is to be inserted and is reproduced on a display unit (1) as a 3D X-ray model (20). A second measuring data set of a three-dimensional optical measurement of the visible surface of the jaw and of parts of the adjacent tooth (11, 12) is prepared in the region of the prosthesis which is to be inserted. The measuring data set of the 3D X-ray image is correlated with the measuring data set of the three-dimensional optical measurement in relation to the geometries. A data set of the prosthesis is prepared as a 3D prosthesis model (40). The 3D prosthesis model (40) is displayed to-scale in the correlated 3D X-ray model (20) on the display unit (1).

Abstract: Disclosed is a method for pictorially representing and determining tissue densities of a body region, especially in the mouth/jaw/face region (1), of a patient. According to said method, a set of three-dimensional image data representing the body region as well as calibration data that is provided as three-dimensional image data and represents a calibration phantom (5, 8, 15) having a previously known density are photographed by generating an image while the tissue densities are derived from a comparison of the calibration data with the image data. The image data and the calibration data are photographed in the framework of the same shot and in an upright position of the patient, particularly during sitting or standing. The calibration phantom (5, 8, 15) is held in the immediate vicinity of the body region (1) that is to be photographed during the shot by means of a fixture (4, 10, 14) which is fixed independently of the patient's body and in a defined relation to the imaging device.

Abstract: Process for planning an operational intervention on a body part, in particular on the jaw, of a patient, whereby within the framework of a recording, a common reference system is defined between a set of patient data that are registering with a recording device and that show the body part in its three-dimensionality, and a model of the body part, whereby the patient is held in place, during the registering of the patient data, with the body part in a securing device (3), which is brought into a defined position relative to the registering device, whereby after registering the patient data, the model (7) is positioned by means of a holding device (8) in a corresponding location in the securing device (3), whereby the holding device (8) is in a defined position relative to the securing device (3), whereby the model (7) in this defined position is secured to the holding device (8) and whereby additional planning steps are undertaken on the model (7) that is secured on the holding device (8).

Abstract: Process for defining a common reference system between, on the one hand, a set of image data, which show the jaw (6) of a patient and which are recorded with an imaging process, and, on the other hand, a treatment template, which is attached in a removable manner during an operational intervention to the teeth of the patient in a defined position and which has a structure that is used to guide an instrument, whereby markers are provided on the treatment template that can be detected by means of the imaging process and that form a reference system, whereby a template blank (13) that is provided with markers (16) is attached to the patient at the site to be treated by means of a hardening impression material (19) on at least one tooth and/or the jaw, whereby the set of image data with the template blank that is used is recorded, whereby the template blank together with the hardened and in particular break-proof impression material is removed and is clamped in a processing device, and whereby the structure that
