Abstract: A method for monitoring the shape of teeth including: producing a three-dimensional digital model of at least one portion of an arch of the patient or “initial reference model”; acquiring at least one two-dimensional image of the arches, referred to as “updated image”, under actual acquisition conditions; analysing each updated image and producing an updated map relating to a piece of discriminating information; optionally determining rough virtual acquisition conditions that approximate the actual acquisition conditions; searching each updated image for a final reference model corresponding to the shape of the teeth, and optionally to the positioning of the teeth, during the acquisition of the updated image; and comparing the shapes of the initial reference model and of the reference model obtained at the end of the preceding steps, referred to as “final reference model”, in order to determine the deformation and/or the movement of teeth between steps a) and b).

Abstract: A system for evaluating an orthodontic appliance. A mobile telephone for, at an “appliance” instant, acquisition of at least one two-dimensional image (“appliance image”) of teeth at least partially representing the appliance in a service position worn by the teeth, and, at a “dentition” instant, acquisition of at least one two-dimensional image (“dentition image”) of the teeth. A computer programmed to execute, for each of a plurality of teeth represented on the at least one dentition and appliance images, the following: determination of dental and appliance attributes relative to the shape of a tooth represented on the at least one dentition image and relative to the shape of the orthodontic appliance on the at least one appliance image, respectively, and comparison of the dental and appliance attributes, followed by determination of at least a decision or at least one score according to the comparison.

Abstract: A method for distributing orthodontic aligners intended for an orthodontic treatment of a user's dental arch. The orthodontic treatment is defined by an initial orthodontic treatment plan. At a current instant during an “anterior” part of the orthodontic treatment, acquiring, on the part of the user and using a cellphone, a current representation of the dental arch. Then, updating the initial orthodontic treatment plan on the basis of the current representation, and defining, on the basis of the updated initial orthodontic treatment plan, a “posterior” part of the initial orthodontic treatment following the anterior part of the orthodontic treatment. Then, designing and manufacturing only the orthodontic aligners necessary for the “posterior” part, referred to as “posterior orthodontic aligners,” the number of posterior orthodontic aligners being more than or equal to 1 and fewer than 20. Presenting the one or more posterior orthodontic aligners to the user.

Abstract: An acquisition kit including: a mobile telephone with an objective lens for acquiring a 2D and/or 3D representation; a holder to which the telephone is fastened, the holder defining an oral aperture to be inserted into the mouth of a user, the objective lens having a view at least partially representing the oral aperture, the view representing at least a first mark selected from:—a categorization mark identifying a category to which a first constitutive component of the holder belongs; and/or—a personalization mark identifying the user and/or pathology of the user and/or dental care professional and/or group of professionals. The kit includes a computer controller programmed to read the first represented mark and to deduce therefrom a first identifier; then record the first identifier and/or prepare and transmit a message to the user and/or dental care professional; and/or to modify the calibration of the telephone.

Abstract: A device including a camera, a processing unit and a screen. The camera configured to, at an updated instant, acquire, by a cellphone or a tablet, an updated image representing a real dental scene. The processing unit configured to determine a virtual dental scene as a representation of the real scene on the updated image and identify an element of the virtual scene which does not comply with an assessment criterion, and highlighting and/or adding a message regarding this element in the virtual scene. The screen configured to display the updated image and present the virtual scene overlaid with the representation of the real scene on the updated image displayed on the screen, in transparent mode or not on the representation. The processing unit, the camera and the screen are configured to communicate with one another. The patient acquires the updated image and observes the screen.

Abstract: A method for training a neural network intended to analyze a dental situation of an updated patient. A historical learning database is created that relates to a dental body and to a spatial attribute associated with the dental body. The historical learning database includes more than 1,000 historical records, with each historical record relating to a respective historical patient. Each record including a set of historical images all depicting the dental body in the historical patient, called “historical dental body” and an item of spatial information including, for the historical patient, a set of values for the spatial attribute, called “historical spatial information.” The neural network is trained, by providing it with the sets of historical images as input and with the historical spatial information as output, with the spatial attribute defining an ordered sequence of variables in a three-dimensional reference frame.

Abstract: A method for generating an image of a dental arch of a beneficiary, called “modified image.” The method includes, at an acquisition time, acquiring a photo depicting the dental arch, called “original image.” The method successively includes processing the original image such that it depicts discriminating information. The method successively includes submitting the original image at the input of a neural network, called “simulation neural network”, trained, based on the original image, to simulate, on the original image, the effect of a dental event, in order to obtain the modified image.

Abstract: A method for enriching a historical learning base. Training of a first neural network to transform first photos of first dental scenes into first hyper-realistic images to simulate the effect of a dental event on the first dental scenes. Submission, to the trained first neural network, of a source photo representing a source dental scene in a dental context, so as to obtain a final image representing, hyper-realistically, the source dental scene after simulation of the dental event. Creation of a descriptor of the final image, or “final descriptor.” Creation of a historical record consisting of the final image and the final descriptor, and addition of the historical record in the historical learning base.
