Corrective Jaw Surgery (Orthognathic Surgery)

Corrective Jaw Surgery (Orthognathic Surgery)An oral and maxillofacial surgeon (OMS) performs corrective jaw surgery, or orthognathic surgery, to correct a variety of minor and major dental and skeletal irregularities, including misaligned jaws, and teeth.

Surgery can improve activities such as breathing, chewing, and speaking. Orthognathic surgery can significantly improve the patient’s appearance, but it is primarily undertaken to address functional issues.  

Oral and maxillofacial surgeon Dr. Landon D. McLain provides treatments to patients in Huntsville, Madison, Florence, Decatur, Scottsboro, Cullman, Athens, Alabama, and surrounding locations.


Who May Need Jaw Surgery?

Patients experiencing the following conditions may require corrective jaw surgery:

  • Difficulty swallowing
  • Problems in chewing or biting food
  • Chronic jaw or jaw joint (TMJ) pain and headaches
  • Excessive wear of the teeth
  • An unbalanced facial appearance from the front or side
  • Facial injury
  • Inability to make the lips meet without straining
  • Open bite (the space between the upper and lower teeth when the mouth is closed)
  • Birth defects
  • Receding lower chin and jaw
  • A protuberant jaw
  • Sleep apnea (breathing issues when sleeping, such as snoring)
  • Chronic mouth breathing

To determine whether the patient is a candidate for corrective jaw surgery, their dentist, orthodontist, and OMS will work together. The OMS surgeon will determine which orthognathic surgery technique is most suitable and perform the actual procedure.

Patients must understand that their treatment, which will likely include orthodontics pre and post surgery, may take a number of years to complete. The OMS and orthodontist will try to provide a realistic estimate of the time required for the patient’s treatment with the understanding that it is a long-term commitment on the part of the patient and their family.


Upper jaw (Maxillary Osteotomy)

In this procedure, the OMS surgeon places incisions in the upper jaw. They then move it up, down, forward, or backward, depending on the patient’s needs, and secure it with screws and plates.

Maxillary Osteotomy can help correct the following conditions:

  • Crossbite
  • Open bite
  • A protuberant or very receded upper jaw
  • Too much or too little teeth showing
  • Reduced facial growth of the midface (midfacial hypoplasia)

The surgeon will cut the bone above the teeth to enable the whole upper jaw, including the mouth’s roof and upper teeth, to move as one unit. They will move the jaw and upper teeth forward until they are correctly aligned to the lower teeth.

This procedure can be planned on a computer to establish whether additional work, such as orthodontics, will be required to address any remaining difference in the fit.

An open bite develops when extra bone grows above the molars. This causes the surface to become angled when it should be flat and even. The surgeon will correct this condition by trimming away or excising the excess bone.

After the jaw is repositioned, the surgeon will use screws and plates to hold the bone in its new placement.


Lower Jaw (Mandibular Osteotomy)

In this procedure, the OMS surgeon divides the lower jaw and moves the front section forward or backward and secures with screws and plates.

Lower jaw surgery can correct the following conditions:

  • Protruding lower jaw
  • Receding lower jaw

The surgeon places incisions behind the molars and lengthwise along the jawbone enabling the front of the jaw to move as one unit. After repositioning the jaw by moving it either forward or backward, the surgeon secures it with screws and plates to allow it to remain in position as it heals.



The initial jaw healing usually requires around six weeks following surgery while complete jaw healing can take up to 12 weeks.
