Fast palatal expansion produces changes primarily in the underlying skeletal structures rather than by the movement of teeth via the alveolar bone. After the palate has been widened, new bone is deposited in the area of expansion so that the integrity of the midpalatal suture usually is re -established inside three – 6 months.
The most commonly recognized indication for rapid palatal expansion is the correction of posterior crossbite. Via the widening of the midpalatal suture, the correction of a posterior crossbite is accomplished fairly readily in a patient in whom the maxillary sutural technique is still patent. Other remedy effects of rapid palatal expansion incorporate: addition of arch length, correction of axial inclinations of the posterior teeth, spontaneous correction of Class II malocclusion and broadening the smile.
