There are extremely rare cases of the bony structure that forms the jaw getting too misaligned that the only way to correct it is to re-position the jaw itself by either lengthening or taking away some of the offending jaw structure. This is considered major surgery and is carried out in medical facilities that can cope with any emergency. After surgery, the bone is given time to heal and lend with the jaws wired shut to prevent dislodging the said jaw. Other more expensive treatments use metal pins, plates, screws and wires to hold the jaw together to obtain the best possible jaw alignment possible. This is the same procedure given to accident victims who sustain injuries to the jaw and support structures to allow their return to a normal life.
