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 correction of a three-dimensional digital model of an arch of a patient or “reference model.” The method includes the following steps: acquisition of at least one two-dimensional image of the arch, called updated image (Ia1;Ia2), in actual acquisition conditions; search, for each updated image, of virtual acquisition conditions providing a two-dimensional image of the reference model, which maximizes the fit with the updated image, or “reference image” (Ir1;Ir2); comparison of the reference image with the updated image to detect differences; and correction of the reference model to reduce said differences to get a corrected reference model.

Abstract: A method for predicting a future dental situation for a patient. Acquiring historical data including at least: previous time point and context parameter values. Acquiring at a time point all the data related to the current dental situation, including at least: the current time point, context parameter values at the current time point, statistical analysis of the historical data and the current data, so as to predict, at a future time point, at least one future dental situation for the current patient. Depending on the future dental situation, (re)evaluation of the benefit of an orthodontic treatment. Steps may include creating a three-dimensional digital reference model, acquiring at least one two-dimensional image, analysing each updated image and creation, searching, for each updated image, and collecting data relative to the updated reference model and relative to the orthodontic appliance.

Abstract: A method for monitoring a property of the appearance of the teeth of a patient, said method including: A) acquiring, by means of a first acquisition apparatus, at least one first two-dimensional image of said teeth and of a first reference gauge, referred to as “initial image”; B) acquiring, by means of a second acquisition apparatus, at least one second two-dimensional image of said teeth and of a second reference gauge having the same appearance as the first reference gauge, referred to as “updated image”; C) standardising the initial and updated images such that the representations of the first and second reference gauges on the standardised initial and updated images have the same appearance; D) before or after step C, marking the same region of the teeth on the initial and updated images; and E) comparing the appearance of said region in the standardised initial and updated images.

Abstract: A method for analyzing a photo to be analyzed representing a dental scene to be analyzed. Submission, to the trained second neural network, of the photo to be analyzed, so as to obtain a descriptor of the photo. The second neural network being trained via a historical learning base including more than 1000 created historical records added in the historical learning base. The historical record including a final image and of a created descriptor of the final image called “final descriptor.” The final image representing, hyper-realistically, the source dental scene after a simulation of a dental event, and being obtained by submitting, a source photo representing a source dental scene in a dental context, to a first neural network trained 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.

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 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.
