AI summary
A method for generating a plan for the orthodontic treatment of a user's dental arch, comprising the following consecutive steps: a) generating an initial model and a final model representing the dental arch at an initial moment and a final moment; b) determining, using a computer, a deformation scenario that transforms, through the movement of the tooth models, the initial model into the final model; c) determining, using the computer, —a duration for performing the deformation scenario; and —intermediate moments between the initial moment and the final moment for performing the deformation of the dental arch according to the deformation scenario.
