Abstract: Method for evaluating a dental situation of a patient. The method having the following successive steps: 1) generating an initial model of at least one dental arch of the patient, preferably by means of a scanner; 2) splitting the initial model in order to define a tooth model for at least some of the teeth represented on the initial model and thereby to obtain a split model; 3) determining an initial support curve of the tooth models in the split model; 4) fixing each tooth model virtually on the initial support curve, preferably by computer; 5) modifying the split model by deformation of the initial support curve according to a deformed support curve, so as to obtain a first deformed model, in which the tooth models are aligned according to the deformed support curve; 6) presenting the first deformed model.

Abstract: A method for enriching a learning base intended for the training of a deep learning device. Production of an updated reference model of a dental arch and segmentation to produce a tooth model for each tooth. Acquisition of at least one updated image of the arch. For each updated image, search for virtual acquisition conditions suitable for an acquisition of a reference image of the updated reference model exhibiting a maximum match with the updated image, and acquisition of the reference image. Identification, in the reference image, of at least one reference tooth zone representing a tooth model by comparison of the updated image and the reference image determination of an updated tooth zone representing the tooth model. Assignment, to the updated tooth zone, of the tooth attribute value or values of the tooth model. Addition of the updated image enriched with value or values in the learning base.

Abstract: A method for monitoring the positioning of the teeth including production of a three-dimensional digital initial reference model of the arches of the patient and, for each tooth, definition, from the initial reference model, of a three-dimensional digital reference tooth model; acquisition of updated image of at least one two-dimensional image of the arches in actual acquisition conditions; analysis of each updated image and production, for each updated image, of an updated map; optionally, determination, for each updated image, of rough virtual acquisition conditions approximating the actual acquisition conditions; searching, for each updated image, for a final reference model corresponding to the positioning of the teeth during the acquisition of the updated image, for each tooth model, comparison of the positionings of the tooth model in the initial reference model and in the reference model obtained at the end of the preceding steps to determine the movement of the teeth.

Abstract: A method for evaluating, by computer, at an “updated” time, the conformity of an orthodontic aligner with a dental arch of a patient, referred to as the “support arch.” The method includes the following successive steps: A) producing a digital three-dimensional model of the support arch in its configuration at the updated time, or an “updated reference model”, and determining from the updated reference model, a support surface for the aligner; B) deforming the support surface on the basis of the geometry of the aligner in order to obtain a deformed support surface; C) comparing an external surface of the aligner with the deformed support surface, then determining, on the basis of the comparison, at least one score for the conformity of the aligner with the support arch.

Abstract: A method for generating a 3D digital, updated, model of a dental arch, including:



Acquiring at least one updated image. Each updated image representing an active aligner attached, in an operating position, to a dental arch, or ‘image with aligner’, or representing the dental arch without an aligner, or ‘image of uncovered teeth’.
Searching in an updated image, referred to as the ‘updated analysis image’, for representations of teeth that are non-compliant with the treatment scenario.
If one or more non-compliant teeth are identified, determining, depending on the updated time, one of an intermediate models, or ‘active intermediate model’, then identifying one or more models of teeth representing the noncompliant tooth or teeth, respectively, in the active intermediate model.
Deforming the active intermediate model until an updated model is obtained that is compatible with at least one of the updated images.

Abstract: A method and associated system. Such is for orthodontic treatment or for assessing shape of an aligner. Within an example, there is participation in communication of an assessment of the suitability of an aligner as a function of the value of: a tooth attribute of an analysis tooth zone of an analysis image, the tooth attribute relating to a separation between the tooth represented by the analysis tooth zone and the aligner represented on the analysis image, or an image attribute of an analysis image, the image attribute relating to a separation between at least one tooth represented on the analysis image and the aligner represented on the analysis image. The analysis image is an image of an aligner in a service position in which it is worn by the patient acquired by a cellphone more than 1 week, and is a photograph, or an image extracted from a film.
