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 for acquiring at least one two-dimensional image of a part of arches of a patient includes steps carried out by the patient or other person who is not a dental health professional, for example, including placing a dental separator in the mouth of the patient in order to separate the lips of the patient and improve the visibility of the teeth during the acquisition of said at least one two-dimensional image, and acquiring, in a mouth closed position and with a personal image acquisition apparatus, said at least one two-dimensional image.

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: A method for analyzing a real dental situation of a patient. The method includes steps, as follows, in succession. At an updated instant, acquisition of an updated image representing a real dental scene as observed by an operator. Determination of a virtual dental scene as a function of the representation of the real dental scene on the updated image. Presentation of the virtual dental scene in transparent mode and overlaid on the real dental scene, or display of the updated image on a screen and presentation of the virtual dental scene overlaid with the representation of the real dental scene on the updated image displayed on the screen, in transparent mode or not on the representation.

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 for determining a contour of the representation, on a photo of an object made up of one or several elements, referred to as an “actual contour.” The method includes the following steps: 1) application of a first treatment to the photo so as to obtain a first image representing a first contour of the object; 2) application of a second treatment to the photo so as to obtain a second image representing a second contour of the object; 3) association, according to a predetermined association algorithm, of each point of the second contour with a point of the first respective contour, then removal of the points of the first contour that have not been associated with a point of the second contour, the first image then representing a corrected contour of the object.

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.
