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.

Orthodontics: More Than Just Teeth Straightening

When asked what their orthodontist does, most people will answer "straightens crooked teeth." Yet there's a good deal more to it than that.

To practice in the field of orthodontics, a dentist must be trained not only in dentistry, medicine, and pharmacy, but in physics and engineering. They must have the touch of a master craftsman, and the eye of an artist. To fully serve their patients, orthodontists must be part scientist, part psychologist, part detective, and part businessman. Becoming an orthodontist requires four years of formal postgraduate training leading to a dental degree, and two more years of graduate studies in orthodontics. But their education doesn't end with a diploma. In many ways, that's where it begins.

Though it may not be obvious from the casual office visit, the practice of orthodontics has changed dramatically in just the last few years. With ongoing research have come continuing advances in ceramic, clear and invisible braces. There are more sophisticated tools to diagnose orthodontic problems, plus innovative materials and techniques to treat them. There are new drugs to control pain, and cosmetic dentistry procedures no one had heard of 10 years ago. Plus, the number of adults getting braces has risen dramatically. This means that now orthodontists must practice adult orthodontics which presents different challenges.

The field continues to change so rapidly that it's estimated orthodontists must acquire an entirely new set of knowledge every two to four years. In fact, in many states, meeting minimum standards for continuing education is mandatory for orthodontists to retain their licenses. In addition to the formal courses is all the time spent reading professional journals and reviewing new products. Fortunately, orthodontists have no lack of opportunity to learn. By the American Dental Association's count, some 3,000 to 5,000 organizations offer continuing education courses to those in the dental profession.

From the hundreds of thousands of hours of specialized training offered annually, each orthodontic professional can choose the courses he or she feels are most needed to expand and update his or her skills.

The practice of orthodontics is a profession, a science, an art, and a lifelong commitment to provide the best and most advanced possible care for your teeth.
