Our Summary

This research paper is about the use of 3D simulation in orthognathic surgery, which is a type of surgery used to correct conditions of the jaw and face related to structure, growth, sleep apnea, TMJ disorders, malocclusion problems owing to skeletal disharmonies, or other orthodontic problems that cannot be easily treated with braces. The paper specifically looks at the accuracy of virtual planning for this type of surgery and how soft tissues (like skin and muscles) respond to these changes.

In simple terms, the researchers are studying how well 3D simulations can help plan complex jaw surgeries and how the softer parts of the face adjust after the surgery. The ultimate goal is to improve the predictive accuracy of surgical outcomes, which can lead to better patient satisfaction and fewer post-operative complications.

Doctor’s Tip

A doctor might tell a patient that following orthognathic surgery, it is important to follow a soft diet for a period of time to allow the jaw to heal properly. This means avoiding hard, crunchy foods that could put strain on the jaw muscles and bones. It is also important to follow all post-operative care instructions provided by the surgical team to ensure a successful recovery.

Suitable For

Orthognathic surgery, also known as corrective jaw surgery, is typically recommended for patients with the following conditions:

  1. Severe malocclusion (misalignment of the teeth and jaws) that cannot be corrected with orthodontic treatment alone
  2. Facial asymmetry due to abnormal growth of the jaws
  3. Difficulty biting, chewing, or speaking due to jaw abnormalities
  4. Sleep apnea or other breathing problems caused by a small or recessed jaw
  5. Temporomandibular joint (TMJ) disorders that are not responsive to other treatments
  6. Facial trauma or injury that has resulted in significant deformity of the jaws

Orthognathic surgery is usually considered as a last resort after other treatment options, such as braces or orthodontic appliances, have been tried and have not been successful in correcting the underlying issues. Patients considering orthognathic surgery should undergo a comprehensive evaluation by a team of oral and maxillofacial surgeons, orthodontists, and other specialists to determine if they are good candidates for the procedure.

Timeline

Before orthognathic surgery:

  1. Initial consultation with a surgeon or orthodontist to discuss treatment options and determine the need for surgery.
  2. Orthodontic treatment to align the teeth and prepare the jaw for surgery.
  3. Pre-surgical evaluations, including imaging studies such as X-rays, CT scans, and facial photographs.
  4. Virtual surgical planning to create a customized treatment plan for the surgery.
  5. Pre-surgical appointments to discuss the procedure, risks, and recovery process.

After orthognathic surgery:

  1. Post-operative care in the hospital or surgical center.
  2. Recovery period, which may include swelling, bruising, and discomfort.
  3. Follow-up appointments with the surgeon and orthodontist to monitor healing and adjust treatment as needed.
  4. Orthodontic treatment to finalize the alignment of the teeth and jaw.
  5. Long-term follow-up to monitor the results of the surgery and ensure the stability of the jaw position.

What to Ask Your Doctor

  1. What are the potential risks and complications associated with orthognathic surgery?
  2. How long is the recovery period after orthognathic surgery?
  3. Will I need to follow a special diet or make any lifestyle changes before or after surgery?
  4. What type of anesthesia will be used during the procedure?
  5. How will the surgery impact my facial appearance and overall function?
  6. Will I need to wear braces before or after surgery?
  7. How long will the results of the surgery last?
  8. How many orthognathic surgeries have you performed and what is your success rate?
  9. Are there any alternative treatments or procedures that could achieve similar results?
  10. What is the cost of orthognathic surgery and will my insurance cover it?
