An Invisalign treatment is a wearable series of clear, removable aligners to help straighten teeth. It is an alternative to traditional metal and wire dental braces. Invisalign aligners are worn every day for six months to two years, depending on the extent of realignment required.

By wearing the aligners 20 to 22 hours a day—whenever you’re not eating—the teeth gradually move to a desired position. Each aligner in the series is designed to move the teeth about 0.25 to 0.3 mm every two weeks, at which time the aligners are replaced with a slightly different set, making the movement of the teeth comfortable and unforced.

Invisalign aligners are made of a strong, thin, non-toxic, medical grade plastic. Three dimensional computer imaging software is used to design each set of aligners, based on a pre-agreed treatment plan.

Invisalign orthodontic aligners are designed, manufactured and marketed by Align Technology Inc., a medical device company based in California, which started commercial sales in 1998. As of October 2011, nearly 68,000 orthodontists worldwide have received formal training in Invisalign treatments.

Since Invisalign was launched in Australia in 2002, more than 1,000 orthodontists in Australia and New Zealand have been accredited in its use. Accreditation is granted only after special training has been completed that covers suitability assessments on prospective patients, familiarity with technological aspects of the aligners and the ability to design tailored treatment plans.

More than 1,650,000 patients in over 50 countries have had an Invisalign treatment since 1998.
