Just as orthodontics repositions teeth, there are some cases where the upper and lower jaw have not developed in a harmonious relationship making it impossible to fit the teeth together with orthodontic treatment alone. In these cases, surgical orthodontics (also known as orthognathic surgery) corrects jaw irregularities to improve the patient’s ability to chew, speak, and breathe and for improved facial appearances. Moving the jaws also moves the teeth, so braces are always performed in conjunction with jaw correction. This helps make sure teeth are in their proper positions after surgery. About 1% of orthodontic patients would benefit from surgical orthodontic treatment.
