Our Summary

The research paper discusses the use of digital technology in computer assisted orthognathic surgery (CAOS), which is a type of surgery performed 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.

Since the introduction of cone beam computed tomography (CBCT), an advanced imaging technique, there has been a significant increase in research related to CAOS. The paper explores the benefits and drawbacks of using digital technology, including hardware and software, in this type of surgery.

The research involved reviewing and analyzing various other studies, including randomized controlled trials, systematic reviews, and case reports. These were sourced from databases such as PubMed, Google Scholar, and the Cochrane database.

The findings show that using CAOS has several advantages such as eliminating time-consuming steps in preparation, enhancing accuracy in treatment planning, and improving overall surgical outcomes. However, they also indicate some drawbacks such as the need for more training and increased costs.

The process of CAOS involves collecting and manipulating data to create a virtual patient, planning the treatment using specialized software, and preparing for the actual surgery. This preparation may also include 3D printing of surgical guides and templates if the procedure is not dynamically guided.

Despite the clear benefits, there are several challenges that prevent the widespread use of CAOS among clinicians. These include the complexity of the procedures, the cost of the equipment, and the need for specialized training.

However, the paper concludes that CAOS is a highly desired, but not widely used, practice for correcting congenital, developmental, or acquired facial deformities. The paper provides insights into the finer details of the CAOS process to help make it more effective and discusses the current limitations and benefits of the software and hardware used.

Doctor’s Tip

One helpful tip a doctor might tell a patient about orthognathic surgery is to follow all pre-operative instructions carefully, such as fasting before surgery and avoiding certain medications. This will help ensure a successful outcome and reduce the risk of complications during and after the procedure. Additionally, it is important to maintain good oral hygiene and attend all follow-up appointments to monitor progress and address any concerns.

Suitable For

Patients who are typically recommended orthognathic surgery are those with congenital, developmental, or acquired pathologies in the dentomaxillofacial region. This may include patients with malocclusion, facial asymmetry, sleep apnea, TMJ disorders, or other conditions that affect the alignment of the jaws and teeth. Orthognathic surgery may be recommended to correct these issues and improve the patient’s overall oral health and facial aesthetics.

Timeline

Before orthognathic surgery, a patient typically undergoes a thorough evaluation by an orthodontist and oral and maxillofacial surgeon. This evaluation may include dental impressions, X-rays, and possibly a cone beam computed tomography (CBCT) scan to assess the alignment of the jaw and teeth. The surgeon will then create a treatment plan, which may involve orthodontic treatment to align the teeth before surgery.

After the treatment plan is finalized, the patient will undergo orthognathic surgery. This surgery is typically performed under general anesthesia and involves repositioning the jaw bones to improve bite alignment and facial symmetry. The surgeon may use computer assisted orthognathic surgery (CAOS) technology, which involves creating a virtual model of the patient’s jaw and teeth to assist in the surgical planning process.

After the surgery, the patient will go through a recovery period, which may include a liquid or soft food diet, pain management, and follow-up appointments with the surgeon and orthodontist. The patient will also continue orthodontic treatment to fine-tune the alignment of the teeth.

Overall, orthognathic surgery can significantly improve the function and appearance of the jaw and facial structures, leading to a better quality of life for the patient.
