New Orthodontic Appliance Can Correct Overbite

Eleven-year-old Janet had a severe overbite and she was serious about improving her smile. "Her overbite was so obvious, I just knew something was wrong. I was afraid she would have problems with her mouth when she got older," recalled Janet's mother.

Most people think an overbite is caused when the upper teeth stick out. Actually, most overbite problems result from a short lower jaw. With modern techniques and a willing child, an orthodontist can help the short lower jaw grow in to line with the upper teeth. In the past the only solution to Janet's problem was headgear that would pull the upper teeth back to match the lower jaw. But Janet's new smile was shaped in just nine months without traditional braces or headgear.

She was one of a growing number of patients able to benefit from a device designed in Europe called a Bionator. Unlike traditional braces, the plastic and wire device is removable, but only for cleaning and eating. Patients must learn to wear it for more than 20 hours a day.

Orthodontic attention while a child is young can often straighten out crooked teeth before they have a chance to get worse. By redirecting the growth of the jaw, orthodontics can often enhance features in the middle and lower parts of the face. Results can be quite striking. In Janet's case, she became more enthusiastic and outgoing as her smile and self-image improved.

Other types of braces that are available today are invisible braces, clear braces, ceramic braces, and a procedure known as Invisalign® .

When children become aware of themselves and those around them, one of the first things they notice is the face. And nicknames like "Fang and "Buck Beaver" can leave a permanent mark on childhood memories. Unfortunately, children can be brutally cruel to each other because they are brutally honest. Correcting an overbite by controlling the source of the problem, jaw growth, orthodontics can help children face growing up with zeal and self confidence.

Crooked Teeth and a Bad Bite

How's your occlusion today? When your jaws meet nicely and teeth are configured properly in your jaw, that's occlusion. When the fit's awry, it's called a malocclusion .

About 2,000,000 Americans know malocclusion inside and out. So what's wrong with a little overbite? For 20% of us, it's a handicap, for 5%, it's a physical and mental hardship. That's why there's orthodontics.

The gist of jaws

The upper jaw, or maxilla, is part of the skull and it doesn't move. In children, the maxilla is joined at the root of the mouth by soft tissue that grows into one bone mass by about age 17. Our upper teeth are a little bigger than the lowers. We call the lower jaw the mandible. When the maxilla and the mandible work properly, they chew, grind, and tear our food, facilitate normal speech, swallowing, and basic oral health. When your jaws don't align well, you may not be able to eat, breathe or communicate normally.

Getting the bite right

Orthodontic theory, and attempts at bite correction, can be traced to ancient Greek and Roman cultures. But until dentists could agree on the problem, each rigged his own correction device. Some of these 19th century "designer" orthodontic appliances were fanciful, some merely crude.

The early orthodontist Edward Angle classified occlusions into three types. His principles are still the standard today.

• Class I occlusion is a "normal" bite. Since there is argument what "normal" is, Class I could be defined as a jaw/bite relationship that seems to be okay and doesn't cause any problems, although there may be some tooth crowding caused by eruption of extra teeth or missing teeth.
• Class II brings us to true malocclusions, in this case, the buckteeth of Bugs Bunny fame. It's certainly more amusing as a cartoon than reality though. Class II lower jaws are usually small and crowded. Along with a protruding upper jaw, the chin recedes. Children with Class II bites, and adults, for that matter, seem especially subject to social derision. Aside from problems with keeping teeth clean, Class Iis can expect cruel jokes.
• Class III malocclusions are relatively rare (5%)and may include a jutting lower jaw and lower teeth that close in front of the uppers (think Dick Tracy). Treatment is complex, and may require bone surgery.

In any case, seeing your dentist on a regular basis is very important. In the case of Class Iis and IIIs, seeing an orthodontist could make a big difference in your self-esteem and make your life much easier.

With more adults seeking treatment their parents couldn't afford when they were youngsters, this is a very exciting time in orthodontics—we have a world of new orthodontic materials that work better and faster.

Heavy metal bands? Most of us have heard the news about braces. They're lighter, smaller, easier to clean—dare we say it—almost comfortable. Plastics and bonding adhesives mean no more heavy metal bands around teeth. Wire and brackets can be "super-glued" directly onto the teeth (Look, Ma, no bands!).

NASA's missile technology has given us Nitinol, a "memory" metal that retains its shape better than stainless steel. Arch wires made of Nitinol exert a light, steady force that stands up to the push and pull of orthodontic appliances. And lingual braces, glued to the back (tongue side) of the tooth, are proving effective in closing moderate gaps. It's like having invisible braces.

A new breed of patient

The best part of new orthodontics for your orthodontist, though, is a willing, and eager patient. Home care is critical to any orthodontic treatment plan. Careful, constant cleaning, wearing your retainers, and avoiding foods that make a mess of all the handiwork is a must. Most adult patients appreciate the investment of time and energy and tend to go about home care with vigor.
