Upper Jaw Surgery (Le Fort I): Repositioning the Maxilla
Upper jaw surgery (Le Fort I) repositions the upper jawbone (maxilla) to correct the bite and midface balance. The maxilla is precisely separated and moved to a planned position — advanced, impacted, or leveled — and fixed with titanium plates and screws through an incision inside the mouth.
What It Addresses
- A recessed upper jaw making the midface look flat
- An open bite at the front teeth
- A gummy smile from vertical excess of the maxilla
- Asymmetry of the upper jaw
Le Fort I is often part of a plan involving orthodontics, and may be combined with lower-jaw surgery (double jaw) when needed. It is carefully planned with 3D-CT, cephalometry, and dental planning so the bite and profile improve together.

Frequently Asked Questions
Can Le Fort I fix a gummy smile?
Yes. When a gummy smile is caused by vertical excess of the upper jaw, Le Fort I can raise the maxilla so less gum shows when smiling.
Does upper jaw surgery leave scars?
No. The incision is made inside the mouth, so there is no scar on the facial skin.
