The complete process of underbite (reverse bite) corrective surgery
Dentofacial orthognathic surgery for underbite is a method used to treat dental crossbite. Based on the individual condition of the patient, doctors select an appropriate surgical plan to achieve optimal postoperative results. The procedure for underbite correction surgery is as follows:
1. The patient lies supine while the surgical area and surrounding tissues are disinfected.

2. General anesthesia is administered, and the osteotomy lines are marked according to the preoperative design.
3. An incision is made at the predetermined site, followed by layer-by-layer dissection to expose the underlying bone tissue.
4. The maxilla is then cut along the designed osteotomy line and moved forward into the proper position to achieve ideal occlusion between the upper and lower jaws.
5. The upper and lower jaws are fixed in place using titanium screws.
6. After completion of the surgery, the wound is thoroughly irrigated and sutured carefully.
Note: Underbite correction surgery may disrupt the alveolar arch curvature and require removal of teeth obstructing osteotomy. Due to its invasive nature, this procedure should be performed at a tertiary-level plastic surgery hospital or the department of plastic surgery in a tertiary comprehensive hospital.
