Could you explain what is corrective jaw surgery?

Jaw surgery: Dentofacial deformity occurs as we age and unequal growth causes our upper and lower jaw bones to become misaligned. Surgery on the jaws will realign your jawbones to a correct and functional relationship. Usually done in coordination with orthodontics to correct compensations in tooth position by the poor jaw position. Most surgery is done intraorally, and under general anesthesia.

Oral surgeon: Corrective jaw surgery usually done to correct what the public calls an "underbite" and "overbite". Any discrepancy of the teeth and jaws fitting together that can not be managed by orthodontics alone. Usually jointly treated by orthodontisit and oral & maxillofacial surgeon.
