Orthognathic surgery, also known as jaw surgery or orthognathic jaw surgery, is a surgical procedure used to correct severe jaw abnormalities and realigns the jaws and teeth to improve the way they work.

These abnormalities can cause difficulties with speaking, eating, breathing, and overall facial harmony.  Orthognathic jaw surgery aims to improve facial aesthetics, functional occlusion (bite),  and the alignment of the jaws and teeth. It can also help with sleep apnoea and snoring.

Types of Abnormalities Addressed with Jaw Surgery:

• Underbite (Prognathism): Lower jaw protrudes forward, causing the lower teeth to extend beyond the upper teeth.
• Overbite (Class II Malocclusion): Upper jaw protrudes forward, causing the upper teeth to overlap the lower teeth excessively.
• Crossbite: Upper and lower jaws are misaligned laterally, causing some upper teeth to bite on the inside of the lower teeth.
• Open Bite: Upper and lower front teeth do not meet when the mouth is closed.
• Facial Asymmetry: Irregularities in jaw growth that result in uneven facial appearance.

Treatment Planning:

• Orthognathic surgery involves a comprehensive evaluation, including X-rays, scans, dental impressions, and 3D imaging to assess the severity and type of jaw misalignment.
• A multidisciplinary team from our practice in London, including oral and maxillofacial surgeons, orthodontists, and sometimes other specialists, collaborates to develop a detailed treatment plan specifically tailored to you.

Orthodontic Jaw Surgery Preparations:

• Before surgery, patients typically undergo orthodontic treatment to align the teeth and prepare them for surgical correction.
• The orthodontic treatment helps ensure proper alignment of the teeth and jaws post-surgery.

Orthognathic Surgical Procedure:

• Orthognathic surgery is performed under general anaesthesia and involves repositioning the jaws to the desired alignment.
• The surgeon makes incisions inside the mouth, so there are no visible scars. The bone or bones involved are then cut, reshaped, and secured in their new position using screws, plates, or wires.
• The surgery can involve the upper jaw (maxilla), lower jaw (mandible), or both, depending on the patient’s needs.
• Post-surgery, the jaws are stabilised using bands or wires, and the patient begins the recovery process.

Recovery and Postoperative Care:

• Recovery varies depending on the complexity of the surgery. Patients may experience swelling, pain, and temporary changes in sensation.
• Your jaws will be wired together for approximately six to eight weeks. This is the time it takes for the bones to heal in a good, strong union. During the time your jaws are wired together, you will find eating, talking and other daily activities somewhat difficult.A soft or liquid diet is usually recommended initially, gradually transitioning to a normal diet as healing progresses.
• Pain management, follow-up visits, and compliance with postoperative instructions from our team are crucial for a successful recovery.

How long does it take to fully recover from orthognathic surgery?

Usually just a couple of weeks for minor surgery. For more complicated surgery, the initial healing phase can last about 6-8 weeks. Complete healing of the jaws can take between 9 and 12 months.

Benefits of Jaw Surgery:

There are many benefits of corrective jaw surgery including:

• Improved facial aesthetics and harmony.
• Correction of bite and chewing problems, enhancing speech and overall oral function.
• Enhanced self-confidence and quality of life.
