Abstract: A method for representing a change in a tooth position includes creating a volume data record of an initial position of teeth in a maxilla or mandible and ascertaining teeth boundaries therefrom. A surface data record is created following a real or virtual change in the tooth position. The surface data record includes surface data of the teeth and/or parts of the volume data record of the jaw in an altered tooth position. The surface data record is referenced with the volume data record via a reference structure. The change in the tooth position in the volume data record is transformed to align teeth boundaries with the surface data of corresponding teeth from the surface data record to move tooth structures contained in the volume data record and concealed under a surface. An altered volume record with the change in the tooth position is then outputted for representation purposes.

Abstract: A method for representing a tooth position under biting forces includes creating first surface data of a portion(s) of a maxilla tooth row and second surface data of an opposing portion(s) of a mandible tooth row, producing a digital surface model from the surface data, creating a data record which includes outer surface data of teeth lying in the portions of the maxilla tooth row and the mandible tooth row in a centric occlusion under biting forces, defining registration regions in the maxilla and mandible in the outer surface data which are not exposed to any force in the centric occlusion, registering the surface data on the outer surface data based on the registration regions, ascertaining movements of individual teeth outside of the registration regions from the outer surface data, transforming the movements ascertained into the surface data, and creating a modified digital surface model under consideration of the movements.

Abstract: A method for producing a computer-aided virtual articulator for dentistry includes recording and collating body-related data from a plurality of persons to provide a data collection, generating a model of a masticatory apparatus from the data collection via statistical methods, and using the model to supplement body-related data recorded from a single patient to provide a simulated individual movement model of the masticatory apparatus of the single patient and to simulate a movement of the masticatory apparatus.

Abstract: A method for recording jaw movements of a patient includes detachably adhering dental brackets to teeth surfaces of the teeth of a lower jaw of the patient, attaching a position marker and a sensor element which detects the position marker to a head of the patient, and recording, via a jaw movement, a relative movement of the sensor element relative to the position marker. The sensor element is attached to a skull of the patient, and the position marker is attached to the lower jaw of the patient via the dental brackets, or the sensor element is attached to the lower jaw of the patient via the dental brackets, and the position marker is attached to the skull of the patient.

Abstract: A method for capturing patient-individual movements of a mandible in relation to a maxilla in a plurality of degrees of freedom. The method includes providing an optical sensor system having an image in an oral cavity of a patient, providing a defined object in the image of the optical sensor system in the oral cavity of the patient, bringing the optical sensor system into a fixed connection to the mandible or to the maxilla, capturing the defined object with the optical sensor system, the defined object having a defined relationship to the other maxilla or mandible, recording a sequence of spatial points of the defined object with the optical sensor system during a movement of the mandible, and storing the sequence of spatial points as a multi-dimensional movement line in a movement data record.

Abstract: A method for determining an individual biting force of a patient includes providing a test piece with a deformable nature, individually pre-shaping a surface of the test piece for the patient so as to obtain at least one of a defined positioning of the test piece on teeth of the patient and on a device supported by at least one of an upper jaw and a lower jaw of the patient, introducing the test piece between the upper jaw and the lower jaw of the patient, biting, via the patient, onto the test piece so as to provide a deformation of the test piece, and determining the individual biting force by examining the deformation of the test piece.

Abstract: A method for planning a treatment includes recording a first data record of three-dimensional image data of surfaces of an upper and lower jaw. A bite plate with cured impressions of the upper and lower jaw and markers is fitted to the patient. A second data record is recorded of three-dimensional image data of surface data of the bite plate without the patient. A movement recorder is fastened to the lower jaw while the patient bites on the bite plate. The bite plate is removed from the patient. Movements of the movement recorder during mastication movements are recorded and stored in a third data record as movement data. The three-dimensional image data of the first data record is combined with the movement data. A registration is performed using the second data record. The mastication movements of the lower jaw relative to the upper jaw are displayed for treatment planning.

Abstract: A method for generating a virtual jaw image includes performing a movement recording method to obtain a movement record which comprises producing at least one position data record over a defined time. A position data record describes a spatial position of a lower jaw to an upper jaw at a specific time. Surface sections of the upper and lower jaw are scanned at the defined time during the movement recording method to obtain a spatial relation of the surface sections during the defined time. Digital upper and lower jaw images are recorded. A position data record of a virtual position of the digital lower jaw image is assigned to the digital upper jaw image. A position data record is selected to obtain a selected position data record. The digital lower and upper jaw images are virtually aligned based on the selected position data record to produce the virtual jaw image.
