Orthognathic Surgery: What is it?
Orthognathic surgery is corrective jaw surgery, which involves one or both jaws being surgically repositioned. It is a treatment suitable and recommended when there is a ‘bad bite’ (malocclusion), which shows as an imbalance between the size and growth of the jaws.
In some circumstances, the top jaw is bigger than the bottom, or it may go the opposite way with the bottom jaw being more prominent than the top. Orthodontic treatment improves the way the teeth are positioned, and in combination with orthognathic treatment, the way the top and bottom teeth fit together can enhance the functionality and aesthetics of your teeth.
Orthodontic treatment is often used in combination with orthognathic treatment. This is because Invisalign treatment or traditional braces only have minor effects on the way the jaws are positioned. Unbalanced jaw sizes have implications for the way jaws function, the appearance of the face, chewing and biting abilities, as well as speech. Therefore, it is crucial to correct this.
Performing Orthognathic Surgery
Orthognathic Surgery is a procedure completed by an Oral and Maxillofacial Surgeon (OMFS). An OMFS has further professional training in the specific areas of jaws, the mouth and facial bones.
Who is it for?
The craniofacial skeleton growth is not complete until adolescents and young adults, which is generally a requirement for Orthognathic Surgery to be performed.
What does the treatment process look like for Orthognathic Surgery?
The entire process has a duration ranges from 18 to 24 months. This factors in treatment planning, orthognathic surgery and orthodontic treatment.
Treatment Planning Phase
This aspect is crucial to understanding the patient’s needs, expected outcomes and associated fees. The first step is the consultation process with your dentist, where dental models, x-rays, photographs and other necessary treatments will be completed. These are diagnostic tools essential to create your written treatment plan. Along with your treatment plan, associated fees and item numbers for health insurance purposes will be provided.
Before Surgery: Orthodontics
For effective surgery, the teeth must be appropriately positioned before jaw surgery. For this to take place, the timeline for orthodontic treatment (braces), usually involves a treatment process of 8 – 16 months.
Once the teeth are adequately positioned, new records are taken to plan the surgical procedure carefully.
For the most ideal surgical outcome, as well as effective healing, there are specific recommendations to be followed and completed. These include:
Smoking is related to increased rates of infection postoperatively and slower wound healing. It is strongly recommended to stop smoking two weeks before your surgery.
Discussing current medications with your surgeon is very important. One month before surgery, no medications aspirin should be taken. For the months post-surgery, aspirin, Ponnstan and Naprogesic medications should be avoided.
A healthy surgical environment is ideal, it is recommended to follow an oral hygiene routine which involves brushing two times a day, as well as flossing.
Depending on the specifics of your surgery, your surgeon may recommend certain blood tests before your admission.
