Abstract: A method for assessing the shape of an orthodontic aligner. Acquisition of at least one analysis image at least partially representing the aligner in a service position in which it is worn by a patient. Analysis of the analysis image by means of a deep learning device, trained by means of a learning base, so as to determine a value. For at least one tooth attribute of an analysis tooth zone representing, at least partially, a tooth on the 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. For an image attribute of the 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.

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.

Deformation of the initial reference model until the tooth models are in a target position. Acquisition of at least one two-dimensional image of the teeth. Deformation of the initial reference model until the at least one updated image corresponds to the initial reference model. Determination, from the updated reference model and from said target reference model, of a plurality of remaining-treatments for moving the teeth from their position represented in the updated reference model into their position represented in the target reference model.

Abstract: Method for acquiring a model of a dental arch of a user (U), said method comprising the following steps: a) at an update time, extra-oral acquisition, with a portable scanner (12), by the user, of a digital three-dimensional model (8) of said arch, and optionally division of the model of the arch so as to isolate one portion (30) of the model of the arch, so as to obtain an “updated model”, the updated model thus possibly being the acquired model or the portion of the acquired model isolated by division, the object represented by the updated model being called the “updated object”.

Abstract: The invention relates to a system for adapting an orthodontic apparatus intended for a patient, said system comprising the following steps: -a) determining, at a parameterisation time, by a first dental healthcare professional and specifically for said patient, conditions for communicating updated information relating to the configuration of the patient's dentition; -b) acquiring, at an updated time subsequent to the parameterisation time, by means of an acquisition device and by the patient or an acquaintance of the patient, an extraoral depiction of at least one portion of the patient's dental arches, referred to as an “updated depiction”, said updated depiction consisting of a set of images and/or of a three-dimensional digital model; -c) analysing said updated depiction, so as to determine information regarding said dentition configuration at the updated time, or “updated information”, the updated information consisting of a set of information elements, each expressing a status for a relevant treatment aim in light of the updated depiction; -d) communicating the updated information to at least one second dental healthcare professional under the conditions determined in step a); -e) adapting said orthodontic apparatus on the basis of the updated information communicated in step d).

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.
