Orthognathic Surgery

Corrective Jaw Surgery Greater Steele Creek and Fort Mill Communities

Orthognathic surgery, also known as corrective jaw surgery, is a type of surgery designed to correct problems with the jaw bones and facial structure, especially when they cannot be resolved with orthodontics (braces) alone. It’s typically performed by an oral and maxillofacial surgeon in collaboration with an orthodontist.

Why It’s Done – Orthognathic surgery is used to treat:

• Jaw misalignment – underbite, overbite, crossbite, open bite
• Facial asymmetry secondary to congenital or acquired malformation
• Sleep apnea or breathing problems
• Aesthetic concerns – improving facial balance and symmetry

How It Works – The Process

1. Diagnosis & Planning
   • Data collection – radiographs and bite records
   • Collaboration with surgeon & orthodontist to determine treatment plan
   • Orthodontics (braces/Invisalign) are started 6–18 months before surgery to align teeth
2. The Surgery
   • Performed under general anesthesia ranging 2-4 hours
   • Surgeons cut and reposition parts of the jawbone, then fixate with plates and screws into new planned position
   • Common types:
     • Le Fort I osteotomy – upper jaw surgery
     • Bilateral sagittal split osteotomy – lower jaw surgery
     • Genioplasty – chin surgery
     • Maxillomandibular advancement – sleep apnea surgery

3. Recovery
   • Possible overnight stay in hospital
   • Initial healing period – 6 weeks
   • Full recovery – approximately 3 months
   • Postoperative orthodontic treatment utilized to fine-tune the bite for 3-6 months
