I am pulling out four teeth, and then dragging all the molars at the back to the front with wire. The mandible will become smaller, and the shape of the lips will not change, or it will be the same as before you put the patch. The correction time should be kept within two years as far as possible, with little damage to the root. It's been too long, and you'll lose your teeth when you get old. Because the roots move back and forth.
