1. A dental simulating method comprising the following steps:
a step of subjecting an original image to a neural network, called the “modification neural network”, trained to locally modify the original image in order to obtain a “modified image”, the original image being a two-dimensional image of a dental arch of a patient and being acquired by a patient with a cellphone, the modified image including a locally modified portion that is generated by the neural network in an artificial way, at the same time as the rest of the modified image;
the modification neural network being trained to:
represent a dental device on an image of a dental arch not bearing the dental device; or
delete the representation of a dental device from an image of a dental arch bearing the dental device; or
replace the representation of a dental device in an image of a dental arch bearing the dental device, with the representation of another dental device;
prior to said subjecting step, said modification neural network being trained with a historical training database, consisting of a set of historical records, each historical record comprising:
a historical image chosen from a photo of a dental scene containing a dental arch not bearing an orthodontic appliance, a view of a dental scene containing a dental arch not bearing an orthodontic appliance, a photo of a dental scene containing a dental arch bearing an orthodontic appliance, and a view of a model representing a dental arch bearing an orthodontic appliance, and
a historical description specifying whether or not the historical image contains an orthodontic appliance,
all orthodontic appliances contained in the historical images being of the same type:
a step of presenting the modified image to the patient.
