1. A non-transitory computer-readable medium storing a computer program comprising program comprising code instructions for the execution of a method for modeling a dental arch of a patient, when said program is run by a computer, said method comprising:
b): analyzing 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, said “analysis image” is acquired with a cell phone before analyzing it;
c): for each analysis tooth zone determined in the preceding step, searching, in a historical library comprising more than 1000 digital three-dimensional tooth models, called “historical tooth models”, for an optimal digital three-dimensional tooth model exhibiting a maximal proximity with the analysis image or with the analysis tooth zone;
d): arranging of all of the optimal digital three-dimensional tooth models so as to create a digital three-dimensional assembled model which exhibits a maximal proximity with the analysis image,
in which said step c) comprises, for assessing the proximity of a historical tooth model with the analysis tooth zone, a comparison of at least one value of a tooth attribute of the analysis tooth zone with the value of this attribute for the historical tooth model.
