Orthognathic surgery is a plastic surgery indicated to correct the positioning of the chin and is done when there are difficulties to chew or breathe due to the unfavorable position of the jaw, in addition, it can be performed with aesthetic purposes to make the face more harmonious.
Depending on the position of the jaw and teeth, the surgeon can recommend two types of surgery:
- Class 2 orthognathic surgery , which is performed in cases where the upper jaw is far in front of the lower teeth;
- Class 3 orthognathic surgery , which is used to correct cases in which the lower teeth are far ahead of those of the upper jaw.
In the case of changes in the growth of the jaw that compromise breathing, rhinoplasty can also be performed to improve air flow. This procedure is more recommended for people over 17, which is when the facial bones have grown sufficiently, however, when the changes are very noticeable in childhood and have an aesthetic and psychological impact on the child, the first correction can be made, the second being performed when the growth of the facial bones has stabilized.

After 2 years of using the device, a simulation of the surgery is performed in order to visualize the final result of the procedure, including the aesthetic results. Then, the surgeon performs the repositioning of the jaw through a surgical procedure that is done inside the mouth. By this procedure, the bone is cut and fixed in another location using titanium structures.

In the case of being performed for aesthetic purposes, the surgery must be performed in private clinics, not being made available by SUS.
