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: An acquisition kit including: a mobile telephone; a mobile telephone holder including: —a spacer opening via an oral aperture, intended to be inserted into the user's mouth, and via an acquisition aperture, and—an adapter fastened to the spacer and defining, with the spacer, a chamber opening via the oral aperture and via an adapter aperture, the adapter including a base to which the mobile telephone is rigidly but removably attached in an acquisition position in which the objective lens of the mobile telephone has an at least partial view of the oral aperture, through the adapter aperture and the acquisition aperture. In the kit, the adapter aperture is laterally offset relative to a clamping zone for clamping the mobile telephone onto the adapter, the clamping zone consisting of the set of points to which the adapter exerts a clamping force on the mobile telephone.

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: 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: 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.

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.
