orthodontic plates / appliances.

Why use an Orthodontic Plate?
An orthodontic plate is a common orthodontic appliance, generally made from plastic and metal. Usually a plate has moulded plastic to sit behind the teeth and a metal wire on the front.Sometimes instead of wire there will be metal prongs to hold the plate to your teeth.It can be used to either:

 - Hold teeth in place (retainer plates); or
Make small corrections to some teeth.
 - How Does an Orthodontic Plate Move Teeth?
One type of orthodontic plate is a retainer. Retainer plates are also known as ‘passive plates’.They are meant to hold your teeth in their current arrangement. An ‘active plate’ is a plate that is making a change to your teeth. In most cases the plate will still look a lot like a retainer. An active plate is a retainer that has been modified to apply gentle force where needed.

A plate may be used to assist with correcting teeth that stick out (or ‘buck teeth’). The front wire can be gradually tightened to move the teeth back into a better position. Orthodontic plates can also be used as preventative measures in children’s orthodontics.

Another reason an orthodontic plate may be used is when the back teeth have drifted too far forwards. The plate will help to move teeth backward: adult teeth not yet out of the gums can sometimes be blocked by crowded back teeth.

A plate may also be used to fix an underbite, also known as a cross-bite of the front teeth. A plate to fix an underbite will usually have springs behind the front teeth. This is used to tip the top front teeth ahead of the lower teeth. Once the teeth have moved a little, the plate will become passive and an adjustment may be needed. During routine checkups with your orthodontist, the plate will be adjusted such that there is once again pressure on the problem area.
