Invisalign (sometimes misspelled as Invisaline) clear tooth aligners are one of the more popular alternatives for those who find the idea of a mouthful of metal braces and brackets – though effective – too unattractive to commit to. If you are a candidate for Invisalign or other “invisible braces”, you don't have to sacrifice your smile while straightening your teeth.
What is Invisalign?
Introduced in 1999 by Align Technologies, Invisalign incorporates a series of invisible (clear) plastic aligners that fit comfortably over your teeth and are designed to move your teeth gradually into the desired position. Today, Invisalign is a leading brand of orthodontic appliance, primarily because the removable aligners (less than one millimeter thick) are designed to be more esthetically pleasing than conventional wire-and-bracket dental braces for treating certain types of minor misaligned tooth problems.
How Invisalign Works
The use of a series of removable aligners for the adjustment of occlusion (bite) is not new. The Invisalign method is based on a concept first introduced in the 1940s and revisited in the 1970s that required a series of dental impressions to determine the optimal position of the teeth. The Invisalign method is simpler than its predecessors, requiring only one set of impressions and photographs of the teeth, taken during an initial consultation.
These impressions are used to create a three-dimensional computer projection of how the teeth could be moved incrementally, forming the basis for developing a series of custom-made aligners designed to accomplish this movement.
Invisalign aligners are manufactured at the Align Technologies dental laboratory using computer-aided design/computer-aided manufacturing (CAD/CAM) processes. The aligners are sent to the orthodontist, who typically dispenses them in groups of one or two at a time during regular check-up appointments (about every four to six weeks) so that treatment can be properly managed. Each aligner must be worn in its specific order for about two weeks, during which time it moves the teeth in small increments of about .25 millimeters to .33 millimeters. Although the aligners are removable (for eating, drinking certain beverages and brushing/flossing), they must be worn at least 20 hours a day in order to reposition the teeth successfully.
A typical Invisalign treatment requires 20 to 30 aligners for both the upper and lower teeth. Most adults complete their treatment in less than one year. However, treatment time depends on the specific alignment problem.
So what happens when you decide Invisalign is for you?
So what happens when you decide Invisalign is for you? Simply visit an Invisalign-trained doctor for a consultation to discuss the goals you have for your smile. Once your doctor determines that Invisalign is right for you, he or she will write up a detailed treatment plan, and a set of virtually invisible aligners will then be sent to your doctor. Your Invisalign system may look like a simple piece of plastic, but it's much more. With advanced technology, your Invisalign aligners are custom-made for you, and only you. Over time, your teeth should move to reveal the smile you've been looking for. So take a look at the steps you and your doctor will take to get you to a brand-new smile.
Your initial consultation with your dentist or orthodontist, is oftentimes offered free of charge. During this visit, you'll discuss the issues you have with your teeth and what kind of results you would like to see. Once your doctor decides your situation is suitable for Invisalign treatment, a treatment plan will be mapped out with your goals in mind. Then, impressions and pictures of your teeth will be taken for digitization purposes.
The impressions of your teeth will be digitized in order for your doctor to work with a computerized 3-D image of your teeth. Then, your doctor will plan your tooth movements throughout your entire treatment timeline. You'll be able to see a virtual representation of your teeth before, during, and after completion of the Invisalign process so you can see what your smile should look like when you're done with treatment.
From your doctor's precise treatment plan, customized aligners are created with advanced technology for you to wear at each stage of your treatment. While the number of aligners varies for each individual situation, a full set of treatment typically includes 20-30 aligners per arch.
You should wear your aligners at all times, with the exception of eating and drinking, in order to complete your treatment in the timeline determined by you and your doctor. You'll go in for occasional checkups, to monitor your progress and to receive your next set of aligners. During the entire treatment process, you'll be able to watch your teeth gradually moving into place. Your smile will, little by little, move into something you'd like to show off. The people around you will be sure to notice your new-found confidence.
Invisalign vs. Traditional Orthodontics
Invisalign may not be appropriate for certain cases of misalignment or complex bite problems. Fixed orthodontic appliances (traditional wire and bracket braces) can be used for complex malocclusions.
Though not as esthetically appealing as clear aligners like Invisalign, today's traditional braces have been improved so they are smaller, less visible and more efficient. These newer wire-and-bracket braces also help to correct misalignment much faster than before.
We in Agave Clinic can determine which treatment option might be right for you. In addition, our orthodontic specialist can advise you about orthodontic treatment alternatives. If Invisalign is not appropriate, traditional orthodontics can still be used for such conditions as:
Crowding and spacing greater than five millimeters.
Skeletal malocclusions.
Discrepancies involving centric-relation/centric-occlusion (how the upper and lower jaw joints and jaw muscles close together).
Teeth that are severely rotated.
Open bites in the front and back of the mouth that need to be closed.
Teeth that are severely tipped.
Upper or lower jaws with multiple missing teeth.
More on Invisalign Treatment
Invisalign is currently approved for adults and teenagers with completely erupted permanent teeth who can faithfully follow the directions for treatment – how long they have to wear the aligners each day, what they can and cannot eat and drink, seeing their dentist for follow-up appointments, etc. For example, dentists recommend that you drink only water while wearing Invisalign trays, to prevent staining of the plastic. If you do not follow treatment recommendations, you may compromise treatment success.
According to researchers and Align Technologies, Invisalign can be used to correct the following types of mild dental problems:
Overly crowded teeth. When there is not enough room in the jaw for all of the teeth to fit comfortably or normally (one to five millimeters).
Widely spaced teeth. When there is too much space between the teeth due to abnormal growth of the jaw or shifting of the teeth due to missing teeth (one millimeter to five millimeters).
Overbite/overjet. When the upper teeth bite over the lower teeth.
Crossbite. When the upper and lower jaws are misaligned, causing one or more upper teeth to bite on the inside of the lower teeth, on either the front and/or sides of the mouth.
What people commonly refer to as an "overbite" is known to dental professionals as "overjet." It occurs when the upper teeth bite over the lower teeth. It's typically caused by either genetics, bad oral habits, or over development of the bone that supports the teeth. This issue can lead to gum problems or irritation, and/or wear on the lower teeth and can cause painful jaw and joint problems.
This occurs when the lower teeth protrude past the front teeth. It's usually caused by undergrowth of the upper jaw, overgrowth of the lower jaw, or both. It can also be caused by
missing upper teeth. This issue can prevent the normal function of front teeth or molars which can lead to tooth wear. It can also cause painful jaw and joint problems.
Mild relapse. After traditional braces have beenremoved, when some relapsing tooth movement has occurred.
