Orthognathic Surgery

What Is Orthognathic Surgery?

Orthognathic surgery is jaw surgery that corrects problems caused by the upper and lower jaws being in the wrong position relative to each other and to the rest of the face. During the operation the jawbones are moved to their planned new positions and fixed with titanium plates and screws. This corrects the bite and balances the proportions of the face.

Problems with the alignment of the teeth can often be solved with braces. But if the cause lies in the jawbones themselves, orthodontics alone is not enough and orthognathic surgery is needed.

When Is It Needed?

• When the lower jaw is clearly too far forward or too far back
• In open bites, where the front teeth do not meet when the mouth is closed
• When there is clear asymmetry of the face and jaw
• When there is difficulty chewing, biting, speaking or closing the lips
• In bite problems that occur together with jaw joint complaints

The Treatment Process

1. Assessment and Planning

Treatment starts with a thorough examination, facial and intraoral photographs, a panoramic X-ray and, when needed, a 3D CT scan. The new position of the jaws is planned digitally together with the orthodontist.

2. Orthodontics Before Surgery

In most patients, braces are used before surgery to bring the teeth into the right position on the jaw. How long this stage takes depends on the condition of the teeth.

3. Surgery

Orthognathic surgery is carried out in hospital under general anaesthesia. Because the incisions are usually made inside the mouth, no visible scar is left on the face. The jawbones are moved to their planned position and fixed.

4. Recovery

There is facial swelling in the first weeks, and you will need a liquid or soft diet. The swelling goes down over time and bone healing is followed with regular check-ups.

5. Orthodontics After Surgery

Once the bone has healed, the final adjustments to the bite are made with braces and treatment is completed.

Aftercare: What to Pay Attention To

• Follow the diet plan you are given and avoid hard foods for the first weeks.
• Keep your mouth clean regularly with the recommended mouthwash and a soft brush.
• Avoid smoking and alcohol, as they slow healing.
• Do not miss your check-ups and post-surgery orthodontic appointments.
