removable appliances

A removable appliance is made from a plastic plate with wires coming from the sides. These grip the teeth to keep the brace in place. Removable appliances have a limited number of uses, mainly because they are restricted to moving single teeth and widening either the upper or lower arches. They are not precision appliances and therefore cannot be used for complicated or fine tooth movements.

For a removable appliance to be effective, it must be worn all the time except when playing sports, eating and for cleaning. In the initial period after a removable appliance is fitted it might feel strange because the plastic plates tend to occupy a bit of space in your mouth, but you will soon get used to it. The mouth also tends to produce more saliva than usual because the brain interprets the presence of the appliance as food; this tends to go after one or two days. You will have regular appointments for adjustments and monitoring of this appliance but if you experience any irritation of the cheek, gum or tongue, your orthodontist can adjust the appliance to make it more comfortable.

Because removable appliances can be removed they are easier to keep clean. This also makes it easier for you to maintain your oral hygiene as you’re able to continue with a proper brushing and flossing routine without having to worry about cleaning around your appliance. Use the cleaning solutions and instructions given to you by your orthodontist to keep your brace clean. You must also keep your removable appliance in a safe place when not being worn in order to prevent loss or damage.

Activator

The activator is a monoblock, which means that it consists of only one appliance which is used for the maxilla and the mandible at the same time. It is made of an acrylic part with metal attachments. This functional orthodontic device works by stimulating muscle activity. When the muscles are tensed up, forces from muscle activities are transmitted to the teeth via the appliance. It can be used for several indications such as deep bites or a posterior position of the mandible.

Fränkel

The Fränkel III functional appliance is used for the therapy of progeny (lower jaw is too anterior) patients which are still in the process of growth. This removable brace is made of acrylic with metal elements. Maxillary growth is promoted by so-called pelots, which exert tension on the soft tissues.
