Removable appliances may be used to move selected teeth, to hold selected teeth in place, to influence growth of the jaws and to influence tooth eruption. They are often used in conjunction with fixed appliances.
Removable appliances cannot be used to treat all orthodontic problems. It takes skill and experience to recognize conditions that can be successfully treated with removable appliances.
Because the patient can easily remove the appliance, good compliance is required to achieve the desired outcome.
These appliances are glued in so children are unable to easily remove them. They are used to expand the upper jaw to allow more room for permanent teeth or to correct a crossbite. They can also be used to hold teeth in place and save room in the mouth for proper eruption of permanent teeth. Some fixed appliances can help children stop sucking their fingers or help retrain a tongue thrust.
