Most of us are quite familiar with what traditional braces look like. But occasionally we see more complex-looking devices being worn by young orthodontic patients: thicker wires that extend outside the mouth, with straps that may go behind the neck or over the chin. What are these devices, and why are they sometimes needed?
In general, orthodontic appliances with external parts braced by the head, neck or chin are referred to as “headgear.” These devices may be used to handle a number of particular orthodontic situations, but they all have one thing in common: They provide the additional anchorage needed to move teeth into better positions.
It may come as a surprise that teeth, which seem so solid, can actually be moved fairly easily over time. This is because teeth are not fixed directly into bone, but are instead held in place by a hammock-like structure called the periodontal ligament. Using a light, controlled force — such as the force of springy wires and elastics in traditional braces — teeth can be moved slowly through the jaw bone, like a stick being pulled through sand.
Of course, to pull a stick through sand, you need a firm anchorage — your legs, for example, bracing against a rock. Most of the time, the back teeth, with their large, multiple roots, provide plenty of support. But sometimes, the back teeth alone aren’t enough to do the job.
If a very large space between teeth is being closed, for example, the back teeth might be pulled forward as the front teeth are pulled back; this could result in poor alignment and bite problems. In other cases, the front teeth may need to be pulled forward instead of back. The back teeth can’t help here; this is a job for headgear.
Some types of headgear have a strap that goes behind the head or neck; they use the entire head as an anchorage. Other types, called “reverse pull” headgear, have a strap that comes over the chin or the forehead; they can pull teeth forward. Headgear can even influence the proper growth of facial structures — that’s why it is usually seen on preteens, whose growth isn’t yet complete.
Headgear is usually worn for 12 hours per day, for a limited period of time. In some cases, rather than headgear, appliances called “temporary anchorage devices” (TADS) may be recommended. These are tiny screws that are implanted into the jawbone in a minimally invasive procedure, and serve a similar function.
While it may not look pretty, orthodontic headgear is capable of moving teeth into their proper positions in a relatively short period of time — and ending up with a great-looking smile is what orthodontics is all about.
We all know Madonna, Seal, David Letterman, Anna Paquin and Michael Strahan (of the talk show Kelly and Michael). What do all of these celebrities have in common? Each has a “signature gap” between their front teeth. Given that they have been in the public eye for quite some time, it's not likely that these famous faces will choose to change their well-known smile. In fact, Michael Strahan has publically stated that he will never close his gap.
However, it is not uncommon for people to desire to fix a small gap in their teeth, particularly in advance of important events, such as weddings. Often times, fixing this small gap requires relatively simple orthodontic movements or tooth straightening. Since the teeth don't have to be moved very far, we can usually use simple appliances to correct the issue within a few months.
In order for us to determine your course of treatment, you'll need to make an appointment with our office for a thorough examination. When we examine you, we'll be looking for a number of items that will affect our treatment recommendation:
- Is there enough room to close the space without creating other bite problems?
- Are the roots of the teeth in reasonably good position to allow for minor tooth movement to close the space? X-rays will be required to make a proper assessment.
- Is there an involuntary tongue habit that has pushed the teeth forward and created the gap? If so, this could be difficult to fix quickly.
- Are the surrounding gum tissues and bone healthy?
Based on our assessment and your individual needs, we may recommend one of the following options:
- Clear retainers, a computer-generated series of clear retainers customized for your bite to move the teeth
- Removable orthodontic retainers to which we will attach small springs or elastics to facilitate the minor tooth movement
- Traditional fixed orthodontic appliances (most commonly known as braces), small metal or clear brackets bonded to your teeth through which tiny wires are used to move the teeth
Regardless of the method we choose, once your teeth have moved into the new position, it is important for you to remember that they must be kept in this position until the bone stabilizes around the teeth. We may therefore advise you to wear a retainer for a few months to a few years, depending on your situation.
