Orthognathic Surgery: Correcting Jaw Position for Function & Facial Harmony
Orthognathic surgery corrects the position of the upper and/or lower jaw when they are misaligned — improving the bite (occlusion), chewing and speech, and facial balance together. Unlike an implant, which adds projection on the bone surface, orthognathic surgery repositions the jawbone to its correct place. It is carefully planned and carried out together with an orthodontist. Performed by dr. Enrina Diah, a craniofacial surgeon.
Function & Aesthetics, Together
Orthognathic surgery is not only an aesthetic procedure. Because it corrects how the upper and lower jaws meet, it improves function — chewing, biting, speech, and in some cases breathing — while also harmonizing the facial profile and proportions.
Three Approaches
The approach is chosen by which jaw is misaligned — assessed with 3D-CT, cephalometry, and dental planning.
Repositions the upper jaw (maxilla): for a recessed maxilla, a gummy smile, or an open bite.
Repositions the lower jaw (mandible): advancing a recessed jaw or setting back an over-projected lower jaw (underbite).
Repositions both jaws together: for more complex discrepancies and the most balanced result.
Most cases involve three stages: aligning the teeth with orthodontics (braces) before surgery, the jaw-repositioning surgery itself, then orthodontic finishing afterward — in close collaboration with our trusted orthodontic partners.
Who Is It For?
- An over-projected lower jaw / reverse bite (underbite)
- An open bite — the front teeth do not meet
- A gummy smile from the position of the upper jaw
- A recessed lower jaw making the chin look small (overbite / retrognathia)
- Jaw or facial asymmetry
- Obstructive sleep apnea requiring structural correction via Maxillomandibular Advancement (MMA)
What to Expect
Frequently Asked Questions
Does orthognathic surgery fix my bite?
Yes. Its main goal is to correct how the upper and lower jaws meet (occlusion), usually combined with orthodontic treatment for a precise bite.
Will I need braces?
In most cases, yes — before and after surgery — to align the teeth with the new jaw position.
Will there be scars on my face?
No. The incisions are made inside the mouth, so they leave no scars on the facial skin.
Are the results permanent?
Once the bone heals in its new position, the jaw correction is lasting.
