    摘要： A system and method for creating a model of a patient's mandible and any teeth supported from the mandible and manipulating the mandible relative to anatomical features of the patient's maxilla. The system uses markers positioned on the mandible and on the maxilla to create a functional mandibular axis that approximates an axis through the condyles of the patient. The functional mandibular axis and geometric and anatomical information about the patient's upper and lower jaw are then used to create prostheses for the patient. The system is also used for making corrections to the prosthesis.

    摘要： Apparatuses, components, devices, methods, and systems for determining and tracking movement are provided. An example apparatus that includes a position indicating system having a first light emitter positioned and oriented to emit light in a first direction, a second light emitter positioned and oriented to emit light in a second direction, the second direction being collinear with and opposite to the first direction; and a third light emitter positioned and oriented to emit light in a third direction, the third direction being different than the first direction and the second direction. The third direction may be offset from the first direction by an offset angle that is an acute angle. The apparatus may also include a screen; an imaging system configured to capture an image of the screen. The first light emitter and the third light emitter may both be configured to emit light toward the screen.

    摘要： In CT visualization software, zones of the right and left temporomandibular joints (TMJs) are visualized sequentially. In a frontal plane, each of the condylar processes of the TMJs are delimited into sections. In a sagittal plane, separate 3D contours of the fossae and the condyles of the TMJs are created. The contours of the condyles are combined with a 3D model of the mandibular teeth, and a 3D model of the mandible with the teeth and the condylar processes is obtained. The contours of the fossae are combined with a 3D model of the maxillary teeth, and a 3D model of the maxilla with the teeth and the contours of the glenoid fossae is obtained. The 3D scene objects obtained are distributed according to side and identification code, and precise tracking of the movement of the condyles and the fossae of the TMJs during movement of the mandible is provided.

    摘要： The occlusal canting identifying tool includes a frame having an elongated horizontal portion and a pair of parallel side arms movably attached to the horizontal portion at opposite ends thereof. The tool further includes a vertical arm centrally positioned on the front of the horizontal portion and a measuring assembly positioned on the rear of the horizontal portion. The measuring assembly includes a protractor rotatably attached to the rear of the horizontal portion, the protractor being configured to rotate on a horizontal axis in relation to the horizontal portion, and a bite plate connected to the protractor, the bite plate being adjustable forward and backward in relation to the protractor. The patient is instructed to bite on the bite plate, and if occlusal canting is present, the degree of canting is quantified by rotation of the protractor.

    摘要： The invention relates to a method for designing a dental appliance for a facial skeleton including dental crowns and the roots corresponding thereto, said method including the following steps: producing a volumetric image of the facial skeleton, in the form an initial digital file, using medical imaging; modifying said volumetric image by means of the computer processing of said initial digital file, and obtaining a modified digital file, said modification including at least one tooth movement with a view to implementing a desired correction of the dentition; designing said dental appliance using said initial digital file and said modified digital file, and producing a file capable of being used by digitally controlled machines capable of manufacturing a dental appliance. In the step of modifying the volumetric image, for each tooth that is moved, the crown thereof is individualized and the root corresponding thereto is associated therewith, characterized in that said volumetric image of the facial skeleton includes the image of the mandibular joint and a record of the movements of the mandible over the course of a plurality of movements of said mandible, so as to account for the possible movements of said joint after capturing the movement of said mandible.
