Abstract: Method of analysis of a diagnostic dental representation showing a dental arch of a current patient in several dimensions. The method includes creation of a learning base including more than 1,000 historical dental structures. Each historical dental structure includes a historical dental representation showing an arch of a historical patient in several dimensions and a historical specification containing a value for at least a first attribute relating to a dental object associated with the historical dental representation. The method includes training of at least one deep learning device by use of the learning base. The method includes submission of the diagnostic dental representation to the deep learning device in such a manner that it determines, for the diagnostic dental representation, at least one value for the first attribute.

Abstract: A method for characterizing an intraoral organ. Modelling the organ as a digital three-dimensional model to be characterized (MTBC), including a mesh of points defining a surface. Placing the MTBC in a standardized configuration with respect to a digital three-dimensional initial reference model (IRM), including a mesh of points, called initial reference points (IRPs), the number of IRPs being less than 20% of the MTBC. Then, determining a final reference point (FRP), for each IRP, by a deformation algorithm. Then, determining a set of values determining the position of the FRP and/or a final elementary surface depending on the FRP, the algorithm determining the positions of the FRPs so that a final reference model consisting of a mesh of the final reference points matches the model to be characterized as closely as possible. Generating a characteristic vector grouping, in an ordered manner, the values determined for all the IRPs.

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 of determining an optimal switchover moment for a hybrid orthodontic treatment of teeth. Creation of a digital three-dimensional model of at least part of a dental arch. 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. Determination of a profile including at least one value for an evaluation parameter. Evaluation of each profile by an evaluation rule. Determination the profile of which is optimal for replacing an orthodontic appliance with an aligner.

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 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 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.
