Orthodontic Appliances
Orthodontic appliances are not just limited to fixed and removable braces. There are many devices available to correct jaw alignment irregularities and reposition the teeth. In some cases, traditional fixed or removable braces are used in conjunction with another type of orthodontic appliance, which serves to fulfill one of the following functions:
Expanding the palate to create space
Closing large gaps between the teeth
Correcting irregularities, such as an elongated mandible (lower jaw) or a short maxilla (upper jaw)
Alleviating crowding in the upper or lower jaw
Types of Orthodontic Appliances
Most types of orthodontic appliances treat a specific irregularity. The nature of your diagnosis points your orthodontist towards the most effective treatment.
Here is a brief overview of some of the most commonly used orthodontic appliances:
Palatal Expanders
These devices widen the upper arch to create room for the eruption of permanent teeth and are used to correct a narrow bite or crossbite. Palate expanders are fairly discreet and work effectively as long as the device is adjusted at the designated intervals. Some individuals experience slight difficulty speaking and eating until they have fully acclimated to the device.
Facemasks (Reverse Pull Headgear)
Facemasks are designed to combat growth discrepancies between upper and lower jaw arches. In the case of a class III malocclusion, where the lower jaw grows faster than the upper jaw, the lower arch can look more prominent. Facemasks pull the upper arch forward and encourage its growth relative to the lower arch. This appliance consists of a frame, which sits on the face, and elastics, which are directly applied to braces attached to the teeth. Facemasks are removable, but must be worn for 10-11 hours a day to expedite treatment.
Headgear
Headgear works to correct class II malocclusions, more commonly known as an overbite. In this case the maxilla (or upper jaw) is growing faster than the mandible (or lower jaw.) Headgear restricts upper jaw growth and allows the lower jaw to catch up. Headgear consists of a labial bow which is inserted into bands on the upper molars attached a strap that is worn behind the neck. In some cases, headgear is used to create space to move the front teeth backwards. As with facemasks, it is typically recommended to wear headgear for 11-12 hours each day.
