Orthodontics and Invisalign
How Invisalign 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 is used to 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.
Orthodontics is for Children — and Adults
Having orthodontic treatment in childhood is ideal in order to take advantage of a youngster's natural growth processes to help move the teeth into proper alignment. Like the rest of the body, the teeth and jaws are now changing rapidly. So at this time it's possible (for example) to create more room for teeth in a crowded mouth by using a “palatal expander” to rapidly widen the upper jaw. This phase of growth modification can shorten overall treatment time and ensure the best result if additional orthodontic appliances are needed.
But remember, healthy teeth can be moved at any age, so you've never “missed the boat” for orthodontic treatment. In fact, about one in five of today's orthodontic patients is an adult. Several new technological developments — including tooth-colored ceramic braces, clear aligners and invisible lingual braces — have made orthodontic appliances less evident, and enhanced the treatment experience for grown-ups. Before treatment, adults are carefully examined for signs of periodontal (gum) disease, which will be brought under control before treatment begins.
Types of Orthodontic Appliances
When you imagine someone wearing braces, you probably picture small metal brackets bonded to the front of the teeth, with a thin wire running through them. This time-tested style remains very popular — but it's no longer the only option. Clear braces use brackets made of ceramic or plastic which, except for the slim archwire, are hardly visible. Lingual braces are just like traditional metal braces — except they're bonded to the back of your teeth (the tongue side) so that no one can see them.
Removable clear aligners are an alternative to fixed orthodontic appliances. They consist of a series of clear plastic “trays” that fit over your teeth exactly; each one moves your teeth a little bit, until they are in the proper position. Whether fixed or removable, each type of appliance may have advantages or disadvantages in particular situations. After a complete examination, the best treatment options for you will be discussed.
Retention & Post Orthodontic Care
Once your orthodontic treatment is completed, it's extremely important to wear a retainer as directed. That's because teeth naturally tend to drift back to their original locations — which is the last thing you want after you've gone to the trouble of straightening them! Wearing a retainer holds your teeth in their new position long enough for new bone and ligament to re-form around them, and helps keep your gorgeous new smile looking good for a lifetime.
