Correcting jaw-growth problems is done by the process of dentofacial orthopedics. Some of the more common orthopedic appliances used by orthodontists today that help the length of the upper and lower jaws become more compatible include:
Headgear: This appliance applies pressure to the upper teeth and upper jaw to guide the rate and direction of the upper jaw growth and upper tooth eruption. The headgear may be removed by the patient and is usually worn 10 to 12 hours per day.
Forsus Appliance: The Forsus appliance consists of springs that connect the upper molars to the lower canines and may not be removed by the patient. By putting pressure on the lower and upper jaws, it can help influence jaw growth and tooth positions. The Forsus works on correcting your bite around the clock and can help correct severe protrusion of the upper teeth.
Palatal Expansion Appliance: A child’s upper jaw may also be too narrow for the upper teeth to fit properly with the lower teeth (a cross-bite). When this occurs, a palatal expansion appliance can be fixed to the upper back teeth. This appliance can markedly expand the width of the upper jaw and also push the molars back into a better biting position.
The decision about when and which of these or other appliances to use for orthopedic correction is based on each individual patient’s problem. Usually one of several appliances can be used effectively to treat a given problem. Patient cooperation and the experience of the treating orthodontist are critical elements in success of dentofacial orthopedic treatment.
