Double Jaw Surgery (Bimaxillary): Aligning Both Jaws

Bimaxillary · Upper + Lower Jaw
by dr. Enrina Diah, Sp.BP-RE, KKF

Double jaw surgery (bimaxillary) repositions the upper and lower jaws in a single surgical plan. For more complex discrepancies, moving both jaws together allows the most balanced correction of bite and facial harmony — something hard to achieve by moving only one jaw.

INDICATIONS

What It Addresses

  • Combined upper- and lower-jaw discrepancies
  • Significant facial asymmetry
  • Severe underbite or overbite
  • A combination of bite issues and midface/lower-face proportion
NOTE
Because it involves both jaws, this procedure most benefits from careful planning — at Ultimo Clinic this is done with 3D-CT, cephalometry, and dental planning, alongside close collaboration with our trusted orthodontic partners. This framework also covers Maxillomandibular Advancement (MMA) pathways for patients requiring definitive treatment for structural sleep apnea.

Frequently Asked Questions

When is double jaw surgery needed?

When the discrepancy involves both the upper and lower jaws, or when moving a single jaw is not enough to achieve a balanced bite and facial harmony.

Yes, its scope is broader because both jaws are planned and repositioned. This makes careful planning with 3D-CT and orthodontic collaboration especially important.
