Method for analyzing a dental situation of a patient

A method for analyzing a dental situation of a patient, called “updated patient”, at an updated instant, said method comprising the following steps:

• analyzing a set of several updated images by means of a neural network so as to obtain an item of spatial information comprising, for the updated patient, a set of values for a spatial attribute, called “updated spatial information”,
• the neural network being trained, before the updated instant, in accordance with a training method comprising the following steps:
• A) creating a historical learning database relating to a dental body and to the spatial attribute associated with the dental body;
• the historical learning database comprising more than 1,000 historical records, with each historical record relating to a respective historical patient, comprising:
• a set of several historical images all depicting said dental body in said historical patient, called “historical dental body”;
• and
• an item of spatial information comprising, for the historical patient, a set of values for said spatial attribute, called “historical spatial information”;
• and
• B) training neural network, by providing the neural network with said sets of several historical images as input and with said historical spatial information as output, with the spatial attribute defining an ordered sequence of variables in a three-dimensional reference frame;
• each image of the set of updated images being acquired by means of an image acquisition device, being compatible with said neural network and depicting said dental body of the updated patient called “updated dental body”,
• the spatial attribute defining:
• a position of one or more noteworthy point(s) of the dental body in a three-dimensional reference frame;
• and/or
• one or more vector(s) between noteworthy points of the dental body and/or between a noteworthy point of the dental body and another point.
