Mandibular Osteotomy, Corrective Jaw Surgery

          Corrective jaw surgery is a surgical procedure to correct irregularities of the jaw bones and adjust the jaws and teeth to improve how they work. Making these corrections may also improve the patient’s facial appearance. This procedure requires collaboration between an orthodontist and a maxillofacial (jaw and face) surgeon for the planning of your treatment, before surgery and during recovery, until healing is complete. Corrective jaw surgery is appropriate after growth stops, usually around the age of 16-17 years old.

 

Why it's done;

Corrective jaw surgery can improve both aesthetics and functions of jaw and teeth as follows;

  • Improve chewing or biting
  • Improve swallowing, speaking and breathing
  • Minimize broken teeth
  • Correct the open bits
  • Balance the facial feature
  • Improve the ability of the lips to fully close comfortably
  • Relieve pain caused by temporomandibular joint (TMJ) disorder
  • Provide relief for obstructive sleep apnea

 

Risks and complication;

          Corrective Jaw Surgery is generally safe when performed by an experienced oral and maxillofacial surgeon, in collaboration with an orthodontist. Risks and complications of the surgery, however, may include:

  • Blood loss  
  • Infection   
  • Nerve injury
  • Jaw fracture
  • Relapse of the jaw to the original position
  • Problems with bite fit and jaw joint pain
  • Need for second surgery
  • Need for root canal therapy on selected teeth
  • Loss of a portion of the jaw

 

How you prepare;

           An orthodontist prepares the teeth before surgery by bracing. This phase usually takes 12 to 18 months before surgery to adjust the level and alignment of the teeth. The orthodontist and maxillofacial surgeon work to develop a treatment plan, involving X-rays, pictures and models of your teeth movement.

 

Surgery process;

          The procedure is usually performed intra oral. Incision scares show on the chin, jaw or around the mouth. The surgeon makes cuts in the jawbones and moves them into the correct position. Once your jaw movement is completed, the mini plate and screws, wires and rubber bands may be used to secure the bones into their new position. Jaw surgery may be performed on the upper jaw, lower jaw, chin or any combination of these.

 

Upper Mandibular Osteotomy;

 

Upper jaw surgery may be performed to correct the following problems:

  • Significantly receded or protruding upper jaw
  • Cross bite
  • Too much or too little of the teeth showing
  • Open bite
  • Reduced facial growth of the middle of the face

          The surgeon cuts the upper jaw so it moves as one unit. The jaw and upper teeth are moved forward or backward until they fit properly with the lower teeth. The surgeon then fixes by using plates and screw to hold the bone in the new position, then shaves or removes the excess bone.

 

Lower Mandibular Osteotomy;

Lower jaw surgery may be performed to correct the following problems:

  • Receding lower jaw
  • Protruding lower jaw

The surgeon makes cuts behind the molars and lengthwise down the jawbone, so the front of the jaw can move as one unit. The jaw can then be moved to its new position either forward or backward. Plates and screws hold the jawbone together as it heals.

Postoperative Care;

 After surgery, you will be provided with guidance and instructions. These usually include:

  • What you can eat
  • Oral hygiene
  • Avoiding tobacco
  • Avoiding strenuous activity
  • Medications to control pain 
  • When to return to work or school, which is usually in1-3 weeks

Jaw healing takes about six weeks after surgery, but complete healing can take up to 12 weeks.

 

 

Results;

Correcting alignment of your jaws and teeth with jaw surgery can result in:

  • Balanced appearance of your lower face
  • Improved function of your teeth
  • Health benefits from improved sleep, breathing, chewing and swallowing
  • Improvement in speech
  • Improved appearance
