Align Technology, makers of the clear aligner teeth straightening system which has treated over 3 million patients worldwide, has launched an app which is available for free to download. The app - 'My Invisalign Smile' - works as a companion to support anyone undergoing Invisalign teeth straightening, and features a number of functions which make keeping track of their orthodontic treatment easier, as well as interesting and fun.

Invisalign aligners are changed in two weekly intervals and the app's image function includes a built-in guide to allow users to capture consistently positioned camera shots of their face, their smile and their teeth as they transition towards their final, corrected position. These shots build up into a gallery which also allows the person undergoing treatment to compare their changing teeth, side-by-side to see exactly how their new smile is taking shape.

It is also possible to create powerful time-lapse videos which display the user's teeth transformation story as it unfolds, capturing and demonstrating just how far they have progressed as their dentition moves incrementally over the weeks.

Another function of the app captures this sense of growing anticipation by allowing users to share images and videos of their transitioning appearance with friends and family and on social media.

The app also provides those in treatment with regular tailored support, advice and reminders (including prompts to change their aligners every two weeks or attend their next dental appointment) synchronised with their individual treatment plan, so that they stay on the right track throughout their treatment.
