Abstract: A method including an acquisition, with an acquisition apparatus, of at least one two-dimensional image of arches of a patient, called “updated image”, in actual acquisition conditions, a separator separating lips of the patient in order to improve the visibility of patient's teeth, said separator including a register mark, wherein the representation of the register mark on the updated image is used to recut the updated image and/or to roughly assess the actual acquisition conditions and/or to guide the positioning of the acquisition apparatus at the moment of the acquisition of the updated image and/or to identify a dental situation and/or an action to be achieved by the acquisition apparatus.

Abstract: A method for acquiring an image of a dental arch of a patient. Activation of an image acquisition apparatus so as to acquire an analysis image of the arch. Analysis of the analysis image by a deep learning device trained by a learning base. Determination, for the analysis image, as a function of the results of the analysis, of a value for an image attribute. Comparison of the image attribute value with a setpoint. Sending of an information message as a function of the comparison, the information message being related to the quality of the image acquired and/or to the position of the acquisition apparatus in relation to said arch and/or to the setting of the acquisition apparatus and/or to the opening of the mouth and/or to the wearing of a dental appliance.

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: An imaging device including a support, a mouth retractor fastened to the support and defining a retractor opening, a colorimetric calibration chart and/or a translucence calibration chart and a light source that is oriented so as to illuminate both the teeth of the patient through the retractor opening and the colorimetric calibration chart and/or the translucence calibration chart. Structure for fastening an image acquisition apparatus to the support in a position in which the acquisition apparatus is oriented so as to receive an image of both the retractor opening and of the colorimetric calibration chart and/or of the translucence calibration chart.

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: Method of enrichment of a reference model to be enriched representing a dental arch. Acquisition, under first real conditions, of a current image of the arch displaying one region. Exploration of the reference model in such a manner as to determine a first view of the reference model, in a first direction of observation the reference image exhibiting a maximum match with the current image. Determination, by comparison of the images, of a first orphan point represented on the current image and not represented on the reference image when the current image is in a first register position in which it is superposed, in the space of the reference model, with the reference image. Addition, in the reference model, of a point on a first straight line parallel to the first direction of observation and passing through the first orphan point in the first register position.
