It is clear that the airway is consistently improved with forward movement of the mandible. Counterclockwise (CCW) rotational movements can be utilized to not only further enhance the final chin position and thus the airway. Class III patients pose a dilemma in that posterior mandibular movements tend to collapse the airway. High angle Class III patients are an ideal group to utilize CCW rotations to mitigate airway effects and also improve facial form while correcting the skeletal malocclusion.
