Removable appliances have wire springs which are attached to a smooth, plastic supporting plate and held securely in the mouth by wire clasps. The springs don’t move as accurately as braces and are therefore limited to simple tooth movements, usually in children who haven’t yet lost all of their baby teeth.
Functional appliances are devices used for growing children and adolescents to correct how the upper and lower jaws fit over each other. They are used as a first stage of treatment before any brace treatment can be carried out.
The most common use of a functional appliance is to encourage an under-developed lower jaw to move forward. The functional appliance holds the lower jaw forward until the teeth, jaws and joints have adapted and the desired jaw position is reached.
Dr Crowther and Dr Phelan use the Herbst fixed functional appliance for its efficient and effective results.
Maxillary expansion appliances
Maxillary expansion appliances are used to widen the top jaw allowing both sets of teeth to fit together better. It is most common in child treatments but can also be successful in adults.
Temporary anchorage devices
Temporary Anchorage Devices or TADs are miniature screws or plates placed in the jaw bone so they can be used as anchor points to influence tooth movement during orthodontic treatment. TADs are used in the treatment of more severe orthodontic problems and can, in some cases, reduce the treatment time and avoid the need for jaw surgery.
Traditional headgear is rarely used at EDGE Orthodontics; however, in under-bite cases reverse pull headgear can be a very effective method of encouraging forward growth of the upper jaw to correct the under-bite. Headgear is usually worn at night.
