A method of generating a three-dimensional digital model of a dental arch of a patient, said method comprising the steps of: A) projection of at least one light beam (30) on the arcade, so as to draw at least one light mark on the arcade; B) simultaneously with step A), moving the arcade through the beam and acquiring, during said displacement, a series of updated images of said arcade each showing an updated projection defined by the projected mark; C) identification of said updated projection on each updated image, then search for a three-dimensional numerical model, called "updated model", having a maximum agreement with the set of updated projections. |
