The different types of orthodontic appliances
Orthodontic treatment may be carried out by many different sorts of appliances which are commonly known as “braces”.
Removable
Simple treatment can be carried out with a removable appliance. A removable appliance is a plate which can be taken out for cleaning purposes. It has delicate wires and springs attached, which move the teeth by gentle pressure.
Fixed
Teeth that need to be guided more accurately than they can be by using a removable plate are fitted with a fixed appliance. These have brackets and bands temporarily stuck to the teeth. A flexible wire joins all the brackets and allows the teeth to be moved. It is not possible for the patient to take the appliance out so it is called a fixed appliance.
Elastics
It may be necessary to attach delicate elastic bands to a fixed brace to help move the teeth. Your orthodontist will advise you on the need for elastics.
Headgear
It is sometimes necessary to wear headgear as an addition to either a fixed or removable appliance. Headgear usually needs to be worn only in the evening or at night. Your orthodontist will discuss whether it is necessary. It is very important to wear as advised otherwise treatment may not progress correctly.
Retainers
The retainers hold the newly straightened teeth in position while the surrounding gum and bone settles. The retainers can be fixed or removable depending on the original problem.
