A method of making an orthodontic therapy device, the use of a scan - reference body, as well as orthodontic therapy device

摘要

The present invention relates to a process for the production of a, for fixing on a bone structure of a patient orthodontic therapy device is formed, which a fastening element for fastening the orthodontic therapy device on a fixing device, which is anchored in the bone structure, comprising the steps of:a) detecting three-dimensional biometric data relating to the environment of a fixed on the fixing means scan - reference body, the assignment of the position and the spatial position of the scan - reference body to the fixing device on the basis of at least one reference feature of the scan - reference body, at least in the jaw region of the patient as well as detecting three-dimensional data of at least one reference feature of the scan - reference body,b) creating a virtual mandibular arch of the patient at the computer from the acquired biometric data and recorded data of the at least one reference feature of the scan - reference body,c) virtual created, of the orthodontic therapy device or at least a portion of the orthodontic therapy device on the computer, on the basis of the virtual mandibular arch of the patient,d) producing a real orthodontic therapy device, or at least a part thereof according to of the virtually created orthodontic therapy device or its part, by means of a computer-controlled fabrication method.The present invention also relates to the use of a scan - reference body to the to patient-specific production of such an orthodontic therapy device, as well as such an orthodontic therapy device.
