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).
