Bimaxillary protrusion involves protrusion of not only the teeth, but also the alveolar bone. Therefore, orthodontic treatment alone does not produce a satisfactory enough result. In this case, the bone itself needs to be corrected through surgery.


Operative Method

1. Bimaxillary Protrusion Surgery through Alveolar Bone Fracture

To push in the upper and lower jaws, two teeth each are extracted from both sides. After an incision is made on the mucous membrane, the bone is cut and ground to secure a space in which the alveolar bone is to be pushed.

After the bone is pushed in, the new occlusal surface is checked using a wafer (a frame used to interlock teeth in the upper and lower jaws) created during virtual surgery. If the chin has been moved by as much as planned, the bone is fixed in position (image). Double Jaw Surgery for Bimaxillary.

2. Protrusion

If the degree of jaw protrusion is not severe (less than by 4 - 5 mm), it can be corrected more expediently through double jaw surgery. The degree of pushing in the alveolar bone can be adjusted. As a result, the risk of side effects, such as the look of a toothless mouth, is lowered. The problems with having a long face and exposed gums can be concurrently remedied.
