Abstract
A method for assessing the shape of an orthodontic aligner. Acquisition of at least one analysis image at least partially representing the aligner in a service position in which it is worn by a patient. Analysis of the analysis image by means of a deep learning device, trained by means of a learning base, so as to determine a value. For at least one tooth attribute of an analysis tooth zone representing, at least partially, a tooth on the analysis image, the tooth attribute relating to a separation between the tooth represented by the analysis tooth zone, and the aligner represented on the analysis image. For an image attribute of the analysis image, the image attribute relating to a separation between at least one tooth represented on the analysis image, and the aligner represented on the analysis image.
