Oral and Maxillofacial Surgeons
aimed to correct wide range of skeletal irregularities that cause
disharmony in teeth and facial facial appearance; as well as interfering
speaking and reduce chewing efficiency, and worst of all, obstruct
breathing. Beside enhancing patient's appearance dramatically,
orthognathic surgery is also performed to correct functional problems.

- inability to make the lips meet without straining
- receding chin

- Upper jaw too long, lower jaw short
|

- Lower jaw too long, upper jaw short
|

- Gummy smile - a lot of gum shown when smiling or at rest
|

- Anterior bite - A space between the upper and lower incisors

- difficulty swallowing
- chronic jaw or jaw joint (TMJ) pain and headache
- excessive wear of the teeth
- unbalanced facial appearance from the front, or side
- facial injury or birth defects
- chronic mouth breathing and dry mouth
- sleep apnea (breathing problems when sleeping, including snoring)
Who Needs Corrective Jaw Surgery?

People
who may benefit from corrective jaw surgery include those with an
improper bite resulting from misaligned teeth and/or jaws. In some
cases, the upper and lower jaws may grow at different rates. Injuries
and birth defects may also affect jaw alignment. While orthodontics can
usually correct bite, or "occlusion," problems when only the teeth are
misaligned, corrective jaw surgery may be necessary to correct
misalignment of the jaws.
