    Abstract: A method for modeling a dental arch of a patient. Creation of a historical library including more than 1000 historical tooth models, and assignment, to each historical tooth model, of a value for at least one tooth attribute value. Analysis of at least one analysis image of the dental arch by means of a deep learning device so as to determine at least one analysis tooth zone and at least one tooth attribute value. For each analysis tooth zone determined in the preceding step, search, in the historical library, for a historical tooth model exhibiting a maximal proximity with the analysis image. Arrangement of all of the optimal tooth models so as to create an assembled model which exhibits a maximal proximity Some optionally steps are possible.

    Abstract: Method for preparing a composed response from a value for at least one dental attribute relating to the dental situation of a patient. The method includes: (d) selection by a composition computer of at least one relevant standard response from a base or standard responses and as a function of the value of the at least one dental attribute; (e) composition of a composed response by the composition computer on the basis of the at least one relevant standard response; (f) optionally, validation and/or modification of the composed response by a controller; (g) presentation of the optionally validated and/or modified composed response. The selection in (d) and the composition in (e) are determined according to composition rules of a composition protocol. Before (e), the composition protocol is selected in a protocol models base and/or is created by selecting a protocol model in a protocol models base and then modifying.

    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. Simulation, for a simulation instant, of the real dental scene represented on the updated image, then determination of a virtual dental scene as a function of the simulation. 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 for generating a three-dimensional digital model of a dental arch of a patient. The method includes projection of at least one light beam onto the arch, so as to draw at least one light mark on the arch, and simultaneously, displacement of the arch across the beam and acquisition, during the displacement, of a series of updated images of the arch each showing an updated projection defined by the projected mark. The method includes identification of the updated projection on each updated image, then search for a three-dimensional digital model, called “updated model”, exhibiting a best fit with all the updated projections.
