What are the indications of orthognathic surgery?
The two most commonly cited indications for orthognathic surgery are functional dental problems and aesthetics considerations.
What orthognathic surgery means?
Jaw surgery, also known as orthognathic (or-thog-NATH-ik) surgery, corrects irregularities of the jaw bones and realigns the jaws and teeth to improve the way they work.
What is model surgery?
Model surgery is the means of anticipating and resolving occlusal problems and predicting the amount of bone removal or addition. The most widely used technique of model surgery for the last two decades in this country has been the Lockwood’s key-spacer planning system (Lockwood, 1974).
What is orthodontic decompensation?
Pre-surgical orthodontic decompensation is precisely the opposite movement to dentoalveolar compensation, that is, by means of an orthodontic treatment, the orthodontist accentuates the patient’s deformity to place the teeth in the correct position that the jaws will have aligned.
What are the different types of jaw surgery?
3 Types of Jaw Surgery
- Maxillary Osteotomy (Upper Jaw) This type of surgery corrects a significantly receded upper jaw, cross bite, or when you have too many or too few teeth showing.
- Mandibular Osteotomy (Lower Jaw) This surgery corrects a significantly receded lower jaw.
- Genioplasty (Chin)
Who invented orthognathic surgery?
One of the first published cases of orthognathic surgery was the one from Dr. Simon P. Hullihen in 1849. Originally coined by Harold Hargis, it was more widely popularised first in Germany and then most famously by Hugo Obwegeser who developed the BSSO operation….

What happens during orthognathic surgery?
During the surgery, patients are put under general anesthesia. The procedure is performed inside your mouth. That means there should be no scarring along outside structures, like the jaw and chin. In some cases, doctors make tiny incisions outside of the mouth, but the blemishes typically fade.
What is LeFort 2 surgery?
The Le Fort II osteotomy is a procedure that can simultaneously correct nasal and occlusal deformities, leading to improvements in a patient’s oral function and facial aesthetics. Despite its potential to correct nasomaxillary deformities, this procedure is rarely performed.
What is jaw surgery called?
Jaw surgery, also called orthognathic surgery, is surgery that helps align your upper jaw (maxilla) and lower jaw (mandible). If your jaws don’t line up, it can affect your bite and make it hard for you to eat and speak. Orthognathic (“ortho nathic”) surgery isn’t a single event.
How long is orthognathic surgery?
The length of your actual surgery is approximately two to three hours per jaw.
When was the first orthognathic surgery?
However, the current concept of surgery first is very different from the previous orthognathic surgery without orthodontic treatment. The first orthognathic surgery procedure was performed by Simon Hullihen in 1848.
