1. A method of operating a system for proposal and augmented visualization of an orthodontic treatment, the system comprising: a display device for augmented visualization, wherein the display device comprises an augmented reality glass or HUD display; a mobile device which is configured for distance measurement; and at least one processor, the method comprising:
recording a three-dimensional image of a face with the mobile device to obtain a three-dimensional facial data record;
segmenting a mouth area of the three-dimensional facial data record;
obtaining a three-dimensional representation of actual teeth to be corrected;
establishing reference objects or reference frames in the three-dimensional representation of actual teeth to be corrected;
determining misalignments of the three-dimensional representation of actual teeth to be corrected by comparing the reference objects or reference frames with reference data;
determining an orthodontic treatment as a three-dimensional tooth data record based on the determined misalignments of the three-dimensional representation of actual teeth; and
overlaying the orthodontic treatment as an augmentation on the mouth area through the display device for augmented visualization such that the orthodontic treatment appears directly superimposed on the mouth area.
