Abstract: A method for monitoring the shape of teeth including: producing a three-dimensional digital model of at least one portion of an arch of the patient or “initial reference model”; acquiring at least one two-dimensional image of the arches, referred to as “updated image”, under actual acquisition conditions; analysing each updated image and producing an updated map relating to a piece of discriminating information; optionally determining rough virtual acquisition conditions that approximate the actual acquisition conditions; searching each updated image for a final reference model corresponding to the shape of the teeth, and optionally to the positioning of the teeth, during the acquisition of the updated image; and comparing the shapes of the initial reference model and of the reference model obtained at the end of the preceding steps, referred to as “final reference model”, in order to determine the deformation and/or the movement of teeth between steps a) and b).

Abstract: A method for monitoring the position of the teeth of a patient includes the following steps: a) modeling a target position of the teeth in the form of a target model; b) after a time interval, modeling an updated position of the teeth in the form of an updated model; c) comparing the target and updated models.

Abstract: Method for monitoring positioning of patient's teeth including the following steps: a) less than three months after the end of an orthodontic treatment, producing an initial reference model of the patient's arches, and, each tooth, defining, from the initial reference model, tooth model; b) acquiring at least one updated image of the arches, under actual acquisition conditions; c) analyzing each updated image and producing, for each updated image, an updated map relative to a piece of discriminating information; d) optionally determining, for each updated image, rough virtual acquisition conditions that approximate actual acquisition conditions; e) searching each updated image for a final reference model corresponding to the teeth positioning during acquisition of the updated image, and; f) for each tooth model, comparing tooth model positions in the initial reference model and in reference model obtained at the end of the preceding steps, in order to determine the movement of the teeth between steps a) and b).
