Types of Braces and Invisalign | Saint Louis South Orthodontics

For the vast majority of orthodontic patients, wearing fixed appliances (commonly called braces) will be a major part of treatment — and those braces, for the most part, will be the familiar silvery-metal type. But while they're still quite popular, traditional-looking metal braces are no longer the only game in town! Let's have a look at some of the options available in orthodontic appliances.

First, we should distinguish between fixed and removable appliances. Fixed appliances like braces are attached to the teeth by metal bands or special cement. They aren't normally taken off until treatment is complete. Removable appliances, such as clear aligners, are typically worn some 22 hours per day, but may be easily taken off as needed. While clear aligners can be effective in treating mild to moderate orthodontic problems, fixed appliances are generally needed for more comprehensive treatment.

Metal Braces

Typically made of high-grade stainless steel, traditional metal braces remain by far the most common type of fixed orthodontic appliances. They consist of metal bands that wrap around the molars in back, and smaller metal brackets that are cemented to the front surfaces of the other teeth. A thin, springy metal wire, running through the brackets, gently guides the teeth into a proper position. This archwire may be fixed to the brackets by flexible elastics, metal ties, or other types of clasps.

There are many good reasons why time-tested metal braces remain popular — because they offer a reliable, effective and economical treatment option. In contrast to the appliances of the past, today's braces are actually smaller, lighter, and more comfortable to wear. If you want a less traditional look, you may be able to choose colorful elastics for the brackets, or other modifications.

Ceramic Braces

Clear ceramic braces are a new variation on the traditional system that provides a far less noticeable method of treatment. They use the same components as traditional braces — except that the brackets on the front side of the teeth are made of a translucent ceramic material that blends in with the tooth's natural color. This system has become a favorite for adults (including some well-known celebrities) because, unless you look closely, it's hard to notice they're there.

Several types of ceramic braces are currently available, and the technology is constantly improving. Their aesthetic appeal is undeniable... but there are a few tradeoffs. The ceramic brackets can be less durable than their metal counterparts; plus, while the brackets themselves don't stain, the elastic bands that attach them to the archwire do (however, these are generally changed each month.) Ceramic braces also cost more than metal — but for many people, the benefit of having an inconspicuous appliance outweighs the costs.

Lingual Braces

While ceramic braces certainly offer a less conspicuous look, there is still another system that allows fixed braces to be truly invisible. In some situations, special appliances called lingual braces can be placed on the tongue side of the teeth. They work the same way other metal braces do — but even though they're made of metal, they can't be seen, because they're hidden behind the teeth themselves!

Lingual braces aren't the proper treatment for every orthodontic condition. Special training is required to install them, and they're significantly more expensive than standard braces. They also generally require a bit more time for the wearer to get used to them, and they may slightly prolong treatment. But if you want the least visible type of fixed appliance — and if you're a candidate for this treatment option — then lingual braces may be just what you're looking for.

Invisalign Clear Aligners

When you hear the word "orthodontics," what comes to mind? Probably a young teenager whose teeth are covered by a latticework of metal. There are indeed many orthodontic patients who fit that description. However, there now exists an increasingly popular alternative to traditional metal braces: Invisalign® clear aligners. As the name implies, Invisalign clear aligners are made of almost invisible polyurethane plastic. Rather than being cemented or bonded to the teeth as metal or clear braces are, clear aligners are completely removable — for important social occasions, for eating, and, most importantly, for tooth-brushing and flossing. This advantage can also be a disadvantage: It means you must resist the temptation to take your aligners out more than is advised. Here are some other advantages of the Invisalign system:

Improved Oral Hygiene

With an orthodontic appliance that is removable, you will be able to clean your teeth much more easily than if you were wearing metal braces.

A Discreet Look

If you consider your orthodontic treatment to be a private matter, or simply feel that metal braces don't fit with your self-image, a practically invisible form of orthodontic treatment might suit you.

More Dietary Choices

To protect metal wires and braces, some diet modifications are necessary. With clear aligners, you can still bite into an apple or a crispy pizza crust.

Comfort

The soft, flexible material of which Invisalign aligners are made will not irritate the soft tissues of the mouth, as metal wires and braces can.

Teeth-Grinding Protection

If you have a teeth-grinding or clenching habit, clear aligners can function as thin nightguards that will protect your teeth from excessive wear.

How Invisalign Treatment Works

Invisalign clear aligners work the same way traditional braces do: by applying carefully controlled forces to teeth to move them into a better position. But they are not made of metal; instead, they are made of clear, flexible plastic.

Here's how it works: Specialized computer software helps us design a plan for moving your teeth from their current positions into the best possible alignment. This movement will be broken down into perhaps several dozen stages. For each stage, the Invisalign company will manufacture two plastic mouth "trays" or "aligners," one to fit over your top teeth and one for the bottom. You will wear this first set of trays for two weeks, for a minimum of 20 hours per day. You will then move on to the next set of aligners in your series to accomplish the next stage of gradual movement. You will keep doing this until your teeth are correctly aligned.

In the past several years, two features have been added to make Invisalign a more appropriate orthodontic treatment method for teenagers. Special "eruption tabs" hold the appropriate amount of space open for molars that have not fully grown in. Invisalign for teens also comes with "compliance indicators" built into the aligner material, which fade with wear. This allows parents, dentists, and the teens themselves, to make sure the trays are being worn as prescribed. Treatment with Invisalign can only be successful if this is the case.

Caring for Your Teeth

As mentioned above, one of the main advantages of the Invisalign system is that the trays can be removed for easy cleaning. So please don't neglect to do this! You'll need to brush your teeth after every meal or snack so that food and plaque do not get trapped in the aligners, which could promote tooth decay and gum disease. Your aligners, too, will have to be cleaned regularly; you can do this by brushing them and then rinsing them with lukewarm water.

Also, please keep in mind that while wearing clear aligners is very different from wearing braces, the importance of retaining your post-treatment results is exactly the same. You'll want to be sure to wear your retainer(s) exactly as prescribed after your treatment is completed to protect your investment in a beautiful new smile.

Invisalign Clear Aligners

There's a technology that's (literally) putting a smile on plenty of young faces: the Invisalign® system of clear, removable aligners made especially for teens! If you (or a teenager you know) are a candidate for this treatment, you might find it's the best fit for your lifestyle: It lets you eat what you want, makes it easier to clean your teeth — and best of all, it's virtually invisible.

Are clear aligners right for you? It all depends on what kind of orthodontic treatment you need. Traditional metal braces still work best in some situations — and you might be surprised to find that they're still a popular option for many teenagers! But now that aligners are being designed specifically for teens, more are choosing them every day.

What is a clear aligner? Basically, it's a thin plastic covering or "tray" that fits over your top and/or bottom teeth. You'll wear a series of aligners that will gradually move your teeth into better positions. Here's how they work: Each aligner is custom-made with the help of a computer program that takes into account exactly where your teeth are now, and how they need to be moved. You'll wear each tray for two weeks or so, to shift your teeth slightly, and then you'll go on to the next, which is slightly different. Over time, all of the small movements will add up to a big change!

A Clear Distinction

Your aligner is designed to be worn 22 hours a day, allowing you to take it off for meals or important social occasions. Yet even when you're wearing it, it's pretty hard for anyone else to tell it's there — a big difference from metal braces! Plus, it offers other advantages that aren't so easy to see.

One benefit of aligners over traditional braces is that they make your teeth easier to clean. Because they're removable, there's nothing to keep you from brushing and flossing everywhere in your mouth, just as you would without appliances. But brushing and flossing can be much harder to do around the brackets and wires of braces — and oral hygiene often suffers.

Some people also suffer irritation to the cheeks and gums from the metal parts of braces. Fortunately, the plastic of an aligner rarely causes that kind of problem. Plus, you won't have to rush into the dental office to quickly fix a protruding wire or reattach a broken bracket. You won't have to watch what you eat, either, because you'll simply remove the aligner at mealtimes.

An Aligner Just for Teens

Clear aligners for adults have been available for over a decade, but until recently they weren't recommended for teens in most cases. Why not? Chiefly, for two reasons: It was thought that teens wouldn't always wear them for the recommended 22 hours per day; also, since many teens have some permanent teeth still erupting (emerging from below the gums), the precisely planned movement of the teeth might be disturbed.

Luckily, technology has come to the rescue. The first problem is addressed by "compliance indicators" located on the aligners themselves. These colored dots fade over time as the aligners are worn in the mouth, showing whether or not you've followed the plan. To solve the second problem, aligners made especially for teens come with "eruption tabs" built in; they are designed to hold space for teeth that have not yet fully erupted.

Today, more people than ever — both adults and teens — are finding that clear aligners suit their needs best. Are you one of them? Why not come in to our office and ask whether clear aligners could work for you.
