Two-jaw surgery
Double Jaw Surgery (Orthognathic Surgery)
Double jaw surgery, or orthognathic surgery, involves repositioning the upper and lower jaws to correct structural imbalances. It is designed to improve both the functional alignment of the teeth and the overall aesthetic harmony of the face.
Who it suits
- Individuals with facial asymmetry or a protruding chin (underbite).
- Patients suffering from functional issues like difficulty chewing or speech problems due to jaw misalignment.
- Those with a receding lower jaw or severe overbite that cannot be fixed by braces alone.
Technique highlights
- Corrects both the upper (maxilla) and lower (mandible) jaw bones simultaneously.
- Utilizes 3D digital scanning and virtual surgery simulation for high precision.
- Focuses on both functional bite correction and aesthetic facial contouring.
Surgical steps
- Comprehensive 3D CT imaging and dental modeling to plan precise bone movement.
- Administration of general anesthesia by a specialist.
- Incisions are made inside the mouth to access and reposition the jawbones.
- Securing the bones in their new positions using biocompatible plates and screws.
- Closing the internal incisions with dissolvable or removable sutures.
Recovery & aftercare
- Hospitalization for 2 days post-surgery for close monitoring.
- Stitch removal typically occurs around 14 days after the procedure.
- Initial recovery takes 2 weeks; swelling significantly subsides within 1 month.
Risks & things to consider
- General surgical risks include bleeding, infection, and prolonged swelling.
- Nerve damage may occur, leading to temporary or permanent numbness in the lips or chin.
- Post-operative bite changes may require additional orthodontic adjustments.
Frequently asked questions
How long is the recovery period?
It usually takes 2-4 weeks to return to basic daily activities, but complete bone healing takes several months.
Do I need to wear braces?
Many modern techniques allow for surgery first, but most patients still need braces after surgery to fine-tune the bite.
What can I eat after surgery?
During the first 2-4 weeks, a liquid or very soft food diet is strictly required to avoid pressure on the jaw.
