Method for analyzing an image of a dental arch

A method for modeling a dental arch of a patient, said method comprising:

• a step a):
• creation of a historical library comprising more than 1000 tooth models, called “historical tooth models”, and assignment, to each historical tooth model, of a value for at least one tooth attribute, said tooth attribute being called “tooth attribute value”;
• a step b):
• 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 associated with said analysis tooth zone;
• a step c):
• 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 or with the analysis tooth zone, or “optimal tooth model”;
• a step d):
• arrangement of all of the optimal tooth models so as to create a model which exhibits a maximal proximity with the updated image, or “assembled model”,
• 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.
