Our Summary

This study aimed to test a new treatment method for patients without teeth who were undergoing jaw surgery. The researchers used computer programs to plan the surgeries and then 3D printed special guides and implants to use during the operations. They then compared the actual results of the surgeries to their original plans to see how accurate the new method was. They measured any differences in the movement and rotation of the upper jaw and how much the lower jaw moved forward. The results showed very small discrepancies, suggesting that this new technique for jaw surgery is accurate and reliable.

FAQs

  1. What is the new treatment method being tested for patients without teeth undergoing jaw surgery?
  2. How were computer programs and 3D printing used in planning and conducting the jaw surgeries?
  3. What were the results and implications of the study on the new technique for jaw surgery?

Doctor’s Tip

A doctor might tell a patient considering orthognathic surgery that advancements in technology, such as computer planning and 3D printing, have made the surgery more accurate and reliable. This can help improve the outcome of the surgery and shorten recovery time. It is important to discuss these new techniques with your surgeon and ask any questions you may have before proceeding with the surgery.

Suitable For

Orthognathic surgery is typically recommended for patients with severe jaw misalignment, also known as malocclusion. This can include patients with underbites, overbites, crossbites, open bites, and other jaw abnormalities. In some cases, orthognathic surgery may also be recommended for patients with obstructive sleep apnea, temporomandibular joint (TMJ) disorders, or facial asymmetry. Patients who have difficulty chewing, speaking, or breathing due to their jaw alignment may also benefit from orthognathic surgery.

Timeline

Before orthognathic surgery:

  1. Consultation with a maxillofacial surgeon to discuss treatment options and determine if surgery is necessary.
  2. Comprehensive evaluation, including X-rays, dental molds, and possibly a CT scan to assess the position of the jaws and teeth.
  3. Pre-surgical orthodontic treatment to align the teeth and create a stable bite for after surgery.
  4. Pre-operative appointments with the surgical team to discuss the surgical plan, potential risks, and post-operative care.

After orthognathic surgery:

  1. Immediate post-operative care in the hospital or surgical center, including pain management and monitoring for complications.
  2. Initial recovery period with swelling, bruising, and discomfort that can last for several weeks.
  3. Follow-up appointments with the surgical team to monitor healing and adjust orthodontic treatment as needed.
  4. Gradual return to normal activities and diet, with ongoing orthodontic treatment to refine the bite and alignment of the teeth.
  5. Long-term follow-up care to monitor the results of the surgery and address any potential complications or issues that may arise.

What to Ask Your Doctor

  1. What are the potential risks and complications associated with orthognathic surgery?

  2. How long is the recovery process after orthognathic surgery and what can I expect during this time?

  3. Will I need any additional procedures or treatments before or after the surgery?

  4. How will my bite and facial appearance be affected by the surgery?

  5. What are the expected outcomes of the surgery in terms of functional and aesthetic improvements?

  6. How experienced are you in performing orthognathic surgery and what is your success rate?

  7. Are there any alternative treatment options available for my condition?

  8. Will I need to follow a specific diet or oral hygiene routine after the surgery?

  9. How long will the results of the surgery last and will I need any follow-up appointments or maintenance treatments?

  10. Can you provide me with more information about the new treatment method involving computer programs and 3D printing that you plan to use for my surgery?
