  • Patent number: 10039615
    Abstract: A method for planning a root canal treatment of a tooth which includes a cavity of a patient. The method includes measuring a surface of the cavity with an optical three-dimensional method to generate three-dimensional measurement data of the cavity. A 3D-model of a guide template is planned based on the generated three-dimensional measurement data. The 3-D model is designed in its dimensions as a counterpart to the cavity. Three-dimensional volume data of the tooth is displayed. A position and an orientation of a root canal of the tooth is determined based on the three-dimensional volume data of the tooth. A guide opening for a tool is planned to expose the root canal. The guide opening is arranged within the guide template so that the guide opening points at an entry point of the root canal and in an entry direction of the root canal.

  • Publication number: 20140030669
    Abstract: The invention relates to a system for carrying out a treatment of a human or animal body by a surgeon, comprising a hand-held instrument (2) having an instrument head (3) that acts on an operating field of the body and supports a treatment tool (12). The system also comprises a computer (4) on which a navigation program is provided to assist the guidance of the instrument head (3), wherein body data representing the part of the body containing the operating field, planning data representing the planned treatment, and instrument data representing the position and orientation of the instrument head (3) are available to the navigation program. A positioning means for recording the instrument data is present, wherein the navigation program compares the instrument data as actual data with the planning data as desired data, and a signalling means (10) is provided, which indicates to the surgeon a deviation of the actual data from the desired data.

  • Publication number: 20090325127
    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).

  • Publication number: 20080310584
    Abstract: The invention relates to a method for generating 3D tomographic images of an object (4), according to which a radiation source (1), in particular an X-ray source is displaced in relation to the object (4). The radiation source (1) emits a conical beam of radiation (2) that strikes the object (4), the radiation that has passed through the object (1) and has been weakened in intensity is captured by a detector (5); which is located in, he conical beam (2) behind the object (4) in relation to the radiation source (1). The radiation source (1) and the detector (5) are combined in a source-detector assembly (7), which is rotated about a rotational axis (6) during the generation of images in the reference system that is defined by the object (4). Said rotational axis (6) is modified during the generation of the images and/or the source (1) and/or the detector (5) in the reference system that is defined by the source-detector assembly (7) is/are displaced during the generation of the images.

  • Publication number: 20070262981
    Abstract: The invention relates to a method for producing 3D tomographic images of an object, whereby a radiation source (1), especially an X-ray source, is moved in relation to the object in a plane of motion (6) about a rotating center. The radiation source (1) emits radiation in a radiation cone (2) whose center beam (3) impinges the object. A correspondingly entrained detector (4) is arranged in said center beam, on the side of the object facing away from the radiation source, and is impinged upon by the radiation attenuated in its intensity by the object. The movement is carried out in such a manner that the center beam (3) is tilted by an angle in relation to the plane of motion (6).

  • Patent number: 6771734
    Abstract: In a method and an apparatus for generating a volume dataset of a subject taking a movement of the subject into consideration, a referencing base is arranged at the subject, so that the positions and the orientations of the referencing base can be acquired during a registration of a series of 2D projections of the subject. The volume dataset of the subject is generated on the basis of the series of 2D projections as well as based on the deviations of the positions and of the orientations of the referencing base from a fixed reference position of the referencing base that are determined for all 2D projections of the series.
