Method for controlling an orthodontic treatment

The invention relates to a method for controlling the position of a patient's teeth, said method comprising the following steps: a) less than 3 months after the start of orthodontic treatment, production of an initial reference model of the arches of the patient, and, for each tooth, definition, from the initial reference model, of a tooth model; b) acquisition of at least one updated image of said arches, in real acquisition conditions; c) analysis of each updated image and production, for each updated image, of an updated map relating to discriminatory information; d) optionally determining, for each updated image, approximate virtual acquisition conditions that approximate said actual acquisition conditions; e) search, for each updated image, a final reference model corresponding to the positioning of the teeth during the acquisition of the updated image, and; f) for each tooth model, comparison of the positions of said tooth model in the initial reference model and in the reference model obtained at the end of the previous steps, to determine the movement of the teeth between steps a) and b ).
