摘要:
Procedure for controlling the positioning of a patient's teeth, the indicated procedure comprising the following stages: a) less than 3 months after the start of orthodontic treatment, realization of a digital three-dimensional reference model of the patient's arches, or «model initial reference "and, for each tooth, definition, from the initial reference model, of a digital three-dimensional reference model of the indicated tooth, or" tooth model "; b) acquisition of at least one two-dimensional image of said arcs, called "updated image", under real acquisition conditions; c) analysis of each updated image and realization, for each updated image, of an updated map in relation to discriminant information; e) search, for each updated image, of a final reference model corresponding to the positioning of the teeth during the acquisition of the updated image, the search being preferably carried out by means of a metaheuristic method, preferably evolutionary, preferably annealing simulated, 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 preceding steps, called the «final reference model» in order to determining the displacement of the teeth between stages a) and b), stage e) comprising: - a first optimization operation that makes it possible to search for the virtual acquisition conditions that best correspond to the real acquisition conditions in a reference model to be tested determined from the initial reference model, and - a second search optimization operation, including testing a plurality of the aforementioned reference models to be tested, the reference model corresponding to the best in the positioning of the patient's teeth during the acquisition of the updated image in step b).Procedimiento de control del posicionamiento de dientes de un paciente, comprendiendo el indicado procedimiento las etapas siguientes: a) menos de 3 meses después del comie
