Understanding Orthodontic Appliances for Jaw Growth Correction

Children and adults who visit orthodontists often feel confused and a little frightened because of the various metal tools and appliances. Knowing the applications of such devices can help ease a patient's mind when undergoing treatment. Dentofacial orthopedics is a specialty that uses appliances to adjust the jaws for ideal compatibility. The American Association of Orthodontics recommends these treatment options for children between the ages of eight and twelve to make adjustments during developmental stages. Adults also experience dental changes throughout their lives and can benefit from dentofacial orthopedic appliances. Some common problems with jaw alignment or development include:

• Underdeveloped lower jaw
• Protrusion of upper teeth
• Malocclusions
• Crossbite
• Overbite

Orthodontic Appliances for Correcting Jaw Growth Problems

Jaw-correcting appliances are either fixed or removable. Fixed appliances are applied to the teeth with the use of cement. Removable appliances require dedication from the patient to wear the devices as instructed. You will receive better results by wearing your orthodontic gear and following the treatment plan designed for your specific needs. Understanding the potential results will help you stay motivated, and parents can help their children to follow recommendations. Some appliances can cause slight discomfort during adjustment periods, but wearing them regularly will help shorten the time frame for treatment. Here are some of the most common appliances for correcting jaw growth problems.

• Headgear: This appliance is removable and consists of a stainless steel facebow and fabric safety strap. The orthodontist fixes metal bands to your upper-back teeth where you attach the facebow. The safety strap wraps around your head and secures the facebow. Headgear affects jaw growth and tooth movement by applying pressure to the upper teeth and maxilla.

• Herbst® Appliance: Typically permanent, these appliances attach to the upper and lower molars to hold the mandible forward. The purpose of this type of treatment is to eliminate an overbite. With expansion screws, the Herbst can also widen the jaw.

• Mara: This appliance pushes the mandible forward to reduce overbite. Crowns are placed on your top and bottom molars, and a metal elbow connects the crowns.

• Bite Corrector: This appliance is combined with braces to correct different malocclusions. Metal bars with enclosed springs apply pressure to both the upper and lower jaws. The placement of such bars will depend on the bite type.

• Bionator: This removable appliance guides the lower jaw so that it grows in proportion to the upper jaw. Children can develop aligned bites by wearing bionators.

• Palatal Expansion: There are two options for placement, fixed, or removable palatal expansions, to fix crossbites. The appliance attaches to the upper-back teeth and widens the jaw.

You will get used to the feeling of most appliances within one month, and the adjustment period is easier if you follow the treatment plan designed by our staff. The average time it takes to correct jaw problems is 12 months, so you can expect to see a more beautiful smile in about one year.
