Abstract: Method for cutting a three-dimensional model of a dental scene, or “scene model.” The method includes acquiring a view of the scene model, called the “analysis view.” The method includes analyzing the analysis view by a neural network in order to identify, in the analysis view, at least one elementary zone representing an element of the dental scene, and assigning a value to at least one attribute of the elementary zone. The method includes identifying a region of the scene model represented by the elementary zone on the analysis view, and assigning, in the region, a value to an attribute of the scene model in accordance with the value of the attribute of the elementary zone.

Abstract: A system for manufacturing an orthodontic appliance. A scanner for creating a numerical three-dimensional initial reference model of at least a part of a patient's arch including one or more teeth. An image acquisition device for acquiring at least one two-dimensional updated image of the arch. The image acquisition device is positioned and oriented in space, relative to the teeth, under actual acquisition conditions. A computer for creating a numerical three-dimensional objective reference model, corresponding to a desired positioning, at a time point of a treatment, of the teeth, and deforming the initial reference model by moving one or more teeth of the initial reference model, to obtain an updated reference model corresponding to the positioning of the teeth on the two-dimensional updated image. A device for manufacturing an orthodontic appliance, based on a comparison, executed by the computer, between the updated reference model and the objective reference model.

Abstract: A method to acquire dental images of a patient with a support defining a chamber that is in communication with an outside of said chamber via a first opening and via a second opening. The method includes the following steps: fixing a mobile phone in front of the second opening; positioning the first opening in front of a mouth of the patient; and acquiring at least one dental image by means of the mobile phone.

Abstract: An acquisition kit, including: a mouthpiece intended for being placed into the mouth of a patient and including a reference mark; and an image-acquisition apparatus including a screen for viewing an image that can be acquired, computer memory containing information on target acquisition conditions, and a computer program comprising program code instructions for displaying on said screen a reference in a position such that, when the reference mark matches the reference on the screen, the acquisition apparatus complies with the target acquisition conditions.

Abstract: A method for analyzing an image, called analysis image, of a dental arch of a patient. The analysis image is submitted to a deep learning device in order to determine at least one value of a tooth attribute relating to a tooth represented on the analysis image, and/or at least one value of an image attribute relating to 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.
