Understanding corrective jaw surgery (orthognathic surgery)

Corrective jaw surgery, also called orthognathic surgery, realigns the upper jaw (maxilla), lower jaw (mandible), or both to correct bite problems, facial asymmetry, and functional disorders. While many people associate jaw surgery with cosmetic changes, its primary goals are to improve oral function—chewing, speaking, breathing—and long-term oral health. When performed by experienced oral and maxillofacial surgeons, these procedures combine precise surgical planning with restorative treatment to deliver both functional and aesthetic benefits.

How corrective jaw procedures work

Corrective jaw surgery is a multi-step process that starts with comprehensive evaluation and advanced imaging. Surgeons use 3D imaging and virtual surgical planning to map bone movement and predict post-surgical outcomes. You can learn more about the technology used for planning on our 3D imaging page: 3D imaging.

Typical steps include:

• Orthodontic preparation: Braces or aligners may be used to position teeth before surgery.
• Surgical repositioning: During orthognathic surgery, bone cuts are made and jaws are repositioned and stabilized with plates or screws.
• Adjunctive procedures: Bone grafting or platelet-rich fibrin may be used to optimize healing and bone support; see our information on bone grafting for dental implants and platelet-rich fibrin.
• Postoperative orthodontics: Final tooth alignment often follows once the jaws have healed.

Anesthesia options and safety are discussed thoroughly before surgery; more details are available on our anesthesia page and preoperative instructions can be found under before anesthesia.

Functional benefits: Why orthognathic surgery matters for oral health

Beyond appearance, jaw alignment directly affects oral health and quality of life. Corrective jaw surgery can:

• Improve bite and chewing efficiency. A well-aligned bite distributes forces evenly across teeth, reducing excessive wear and the risk of fractures.
• Reduce or resolve TMJ pain and dysfunction. Patients with misaligned jaws often experience temporomandibular joint (TMJ) disorders; corrective jaw surgery can be part of a treatment plan for TMJ and TMD.
• Improve speech. Jaw position affects tongue space and articulation; surgical correction can improve certain speech impediments.
• Enhance breathing and airway function. In some cases, jaw advancement increases airway volume and helps relieve obstructive sleep apnea symptoms—an important functional benefit often coordinated with sleep apnea specialists (sleep apnea).
• Facilitate long-term restorative care. Proper jaw position creates a stable foundation for restorations such as crowns, bridges, and dental implants. For patients considering implants, our resources on dental implants, bone grafting, and long-term implant benefits provide helpful context: Comprehensive guide to dental implants and Long-term benefits.

How appearance can improve—and why it matters

Facial balance and symmetry are natural outcomes of correct jaw alignment. When jaws are repositioned to a more anatomically ideal relationship, facial proportions—such as the relationship between the nose, lips, and chin—often improve. These changes can:

• Boost self-confidence and social comfort.
• Improve facial proportions and profile harmony.
• Eliminate compensatory facial expressions or postures that form over time due to a poor bite.

Because aesthetic improvements are a common concern, our surgeons use virtual planning to show expected outcomes and set realistic goals before treatment begins. You can meet our surgical team to discuss personalized results on our Meet Us page, including profiles for Dr. Thai Vuu, Dr. Michael Oshell, and other specialists.

Who is a candidate for corrective jaw surgery?

Common indications include severe overbite, underbite, crossbite, open bite, facial asymmetry, and significant functional issues such as difficulty chewing or chronic jaw pain. Adolescents and adults can both be candidates—orthodontic coordination is essential when teeth movement is required before or after surgery.

If you’ve experienced problems with impacted teeth or complications from wisdom teeth, those issues may influence treatment planning. Learn about impacted wisdom teeth and extraction considerations here: impacted wisdom teeth and wisdom teeth removal.

Preparing for surgery and what to expect during recovery

Preparation typically includes medical evaluation, orthodontic work, imaging, and a clear discussion of anesthesia and postoperative care. Preoperative resources such as our first visit and surgical instructions pages explain what to bring, fasting requirements, and planning for recovery time.

After surgery, common expectations are swelling, temporary changes in sensation, and a diet modified to soft foods as the jaws heal. Our patient resources include specific guidance on diet and recovery: soft foods after oral surgery and instructions for various surgical procedures such as extractions and multiple extractions.

Long-term outcomes and maintenance

When orthognathic surgery is combined with appropriate orthodontic care and oral hygiene, results are stable and often life-changing. For patients who receive dental implants as part of restorative care, long-term success depends on good oral hygiene and maintenance—see our pages on maintaining dental implants and dental implant FAQs. If bone grafting is used, follow-up care supports bone health and implant integration (jawbone loss).
