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: 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: Imaging device to acquire dental image having a support. The device includes a rigid portion on which an acquisition apparatus is to be fastened and a deformable portion defining a retractor opening. Associated method to manufacture a support of an imaging device to acquire dental image. The method includes manufacturing of a precursor of the support, in a first place, and providing the precursor to an operator, in a second place away from the first place. The distance between the first place and the second place is preferably greater than 1 km and/or less than 20 000 km. The method includes transformation of the precursor into the support.

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.

Abstract: A method for evaluating an orthodontic appliance. Acquisition of a two-dimensional “appliance image” of teeth at least partially representing the orthodontic appliance in a service position. Acquisition of a two-dimensional “dentition image” of the teeth. If a determination of comparable dental and appliance attributes is not possible from the appliance image and from the dentition image, respectively, conversion of the appliance image and/or of the dentition image so that the appliance image be compatible with the dentition image. Determination of dental and appliance attributes relative to the shape of the tooth represented on the dentition image and relative to the shape of the orthodontic appliance on the appliance image. Comparison of the dental and appliance attributes, followed by determination of at least one score. At least one image is acquired with a mobile phone.

Abstract: Method for monitoring positioning of patient's teeth including the following steps: a) less than three months after the end of an orthodontic treatment, producing an initial reference model of the patient's arches, and, each tooth, defining, from the initial reference model, tooth model; b) acquiring at least one updated image of the arches, under actual acquisition conditions; c) analyzing each updated image and producing, for each updated image, an updated map relative to a piece of discriminating information; d) optionally determining, for each updated image, rough virtual acquisition conditions that approximate actual acquisition conditions; e) searching each updated image for a final reference model corresponding to the teeth positioning during acquisition of the updated image, and; f) for each tooth model, comparing tooth model positions in the initial reference model and in reference model obtained at the end of the preceding steps, in order to determine the movement of the teeth between steps a) and b).

Abstract: Method for acquiring a model of a dental arch of a user (U), said method comprising the following steps: a) at an update time, extra-oral acquisition, with a portable scanner (12), by the user, of a digital three-dimensional model (8) of said arch, and optionally division of the model of the arch so as to isolate one portion (30) of the model of the arch, so as to obtain an “updated model”, the updated model thus possibly being the acquired model or the portion of the acquired model isolated by division, the object represented by the updated model being called the “updated object”.
