Class 3 - Surgical
When the disparity between the size of the upper and lower jaws is so great that alignment cannot be attained by orthodontics alone, surgery can be used to enlarge and/or bring forward the upper jaw; or it can be used the bring the lower backward – or both.
Surgical Correction of Class 3 Malocclusion
As the lower jaw grows beyond the upper, the drape of the lips and cheeks limit the movement of the lower front teeth and cause them to tip backward. This was first described as “compensatory change.” This must first be corrected before the upper and lower jaws are moved into a proper fitting relationship.
