A definition
Orthognathic surgery — literally “straight jaw” surgery — repositions the upper jaw, lower jaw or chin to correct a discrepancy in how the jaws relate to each other and to the rest of the face.
It is different from orthodontics, which moves teeth. When the underlying problem lies in the position or size of the jaw bones themselves, orthodontics alone may not be able to achieve a stable, functional bite.
Why it may be recommended
Orthognathic surgery may be considered for patients with skeletal discrepancies that affect:
- Biting and chewing
- Speech
- Lip closure at rest
- Facial balance and symmetry
- The airway, in selected patients
- Jaw function
A team approach
Treatment is typically planned jointly by the surgeon and an orthodontist. Braces are usually placed before surgery to align the teeth, and continued afterwards to refine the bite.
Every plan is individual. The findings of the clinical assessment and imaging determine which movements, if any, are appropriate.
