Invisalign is the brand name of a type of thin clear aligner used in orthodontic treatment. The aligner is made from a flexible thermoplastic material named SmartTrack. As the name suggests, this product is designed to make orthodontic treatment “less conspicuous,” as the American Association of Orthodontists puts it. Although Invisalign aligners may not be completely invisible, these clear coverings fit tightly over your teeth and are much less noticeable than the brackets and wires of traditional braces
Invisalign can be used for a variety of purposes, including crowding and spacing issues, as well as some mild and moderate bite issues.
The Invisalign website claims that it can be used to treat the following dental issues:
You may have friends who’ve had a good experience with Invisalign, but it’s important to go beyond the anecdotal evidence. At the moment, however, there’s not a lot of research that points to its effectiveness.
A 2015 review of 11 studies involving the use of Invisalign aligners notes that research on their effectiveness is limited.
Studies that have been done up until now tend to have small sample sizes, and many studies haven’t included a control group to use as a comparison.
A 2016 study in the Journal of Orthodontics also warns of the lack of clinical research to bolster claims of effectiveness.
However, based on some available researchTrusted Source, Invisalign does seem to be more effective than other types of clear aligners. And the newer versions that the manufacturer began producing in 2010 seem to have enhanced the effectiveness of Invisalign by improving the delivery of force upon the wearer’s teeth.
On a biological level, Invisalign and traditional braces use the same mechanism of action, “Tooth movement requires bone resorption and bone deposition—the only difference between the actions of Invisalign and traditional braces is the precision of the tooth movement [that is uniquely] programmed into each clear [Invisalign] aligner,”.
Not only are Invisalign trays less visible than traditional braces, but the aligners can be removed while you’re eating, brushing your teeth and flossing, Because traditional braces stay on your teeth for the duration of your treatment, the foods you can eat are limited, whereas there’s no restriction when wearing Invisalign (although dental hygiene, such as brushing and flossing after eating, is critical during Invisalign treatment). What’s more, pain or discomfort during treatment tends to be less severe due to the small movements made by each aligner,
Invisalign clear aligners are virtually invisible, so people may not notice patients are wearing themand there are no metal brackets or wires that could irritate the mouth or break.
Choosing to straighten your teeth with the Invisalign system (or traditional braces) also benefits the longevity of your natural teeth, Straight teeth are easier to clean and don’t develop as much plaque and bacteria buildup that can lead to gum disease and eventual tooth loss,
What’s more, straight teeth keep the forces of your bite balanced so that your teeth are less likely to wear down and chip over time. “All these benefits lead to maintaining your natural teeth for a long time, which is always a goal I have for my patients as a dentist,”
If you have healthy teeth and you don’t have gum disease, you’re probably a great candidate for Invisalign, Sometimes, a patient’s teeth may be structurally compromised or have other complex issues that can only be detected after a comprehensive exam, so it is important to have X-rays done by a dentist or orthodontist prior to starting treatment.
Patients with a history of periodontal disease may also benefit from the system as long as the gum disease is well-controlled at the start of treatment because Invisalign allows for slow tooth movement and proper hygiene
