Abstract
Embodiments relate to aligners that are capable of immobilizing a patient's jaw after orthognathic surgery while also applying forces to reposition a patient's teeth. In embodiments, a processor determines, for a treatment stage, a dentition for an upper dental arch and a lower dental arch. The processor applies one or more stabilizing features to the upper dental arch and the lower dental arch. The processor determines whether the one or more stabilizing features will prevent jaw movement while the upper dental arch is engaged with the lower dental arch. Responsive to a determination that the one or more stabilizing features will prevent the jaw movement, the processor stores a first digital model comprising the dentition for the upper arch and the one or more stabilizing features for the upper arch and stores a second digital model comprising the planned dentition for the lower arch and the one or more stabilizing features for the lower arch for each increment of treatment.
