Evaluation of the Airway Space After Distalization in Adults Using the Carrière Motion Appliance: A Cone-Beam Computed Tomography (CBCT) Study.

Background: Distalization can be done with either intraoral (IO) or extraoral (EO) appliances and is one of the most prevalent methods for correcting class II molars. In recent decades, it has become more pervasive to treat class II malocclusions without taking teeth out. Persons with a neutro-basal jaw base relationship should distalize their teeth to make the dental arch wider in order to prevent the need to remove permanent teeth.
