People who benefit from Corrective Jaw Surgery include those with an improper bite, or jaws that are positioned incorrectly. Jaw growth is a gradual process and, in some instances, the upper and lower jaws grow at different rates. Improper jaw growth can lead to a variety of problems that affect chewing function, speech, nasal breathing, long-term oral health, and appearance. Injury to the jaw and birth defects can also affect jaw growth and alignment. While orthodontics alone can correct bite problems if only the teeth are involved, Corrective Jaw Surgery is required if the facial bones need repositioning.
