The invention relates to a method for optimising initial discriminating information extracted from a two-dimensional image of the dental arches of a patient, referred to as "acquired image", by means of a three-dimensional digital reference model of at least one portion of an arch of the patient, said method including the following steps: C1. assessing the quality of the initial discriminating information and a quality threshold, filtering so as to keep only the initial discriminating information that has quality higher than the quality threshold, and defining "the discriminating information to be tested" as being the initial discriminating information selected; C2. testing a consistency between the discriminating information to be tested and said reference model; C3. assessing the result of the test and, in accordance with said assessment: adding discriminating information that was not kept to the discriminating information to be tested and/or deleting discriminating information from the discriminating information to be tested, and then returning to step C2. or; defining the optimal discriminating information as being the discriminating information to be tested. |
