The Invisalign brand celebrates major milestone with treatment of 3 millionth patient

Align Technology, Inc., (NASDAQ ALGN) the worldwide market leader in clear aligner orthodontics, today announced that 3 million patients have now started treatment with the Invisalign system, the modern approach to straightening teeth. This is a significant milestone in Invisalign treatment and reflects an accelerating rate of adoption worldwide by Invisalign-trained doctors and their patients. To mark the milestone, Align Technology has teamed up with Operation Smile to help children across the globe born with cleft lip and cleft palate. Beginning today, Align Technology will donate $1 for every public share of a photo of a person's smile on Facebook, Twitter, or Instagram with the hashtag #3millionsmiles - for a total donation of up to $1 million.*

"This major milestone was achieved in partnership with our network of Invisalign providers in more than 80 countries around the world," said Thomas M. Prescott, Align Technology president and CEO. "We are proud to be helping these doctors transform smiles with Invisalign treatment as more and more people realize the benefits of straightening their teeth without brackets and wires. And we hope to inspire others to give more smiles to children around the world with our pledge to Operation Smile."

Contributing to this achievement is the expansion of Invisalign treatment in international markets, specifically Europe and Asia, combined with Align Technology's ongoing commitment to deliver new products and features that provide doctors with increased clinical confidence to straighten teeth. By combining biomechanics research, 3D software technology, cutting-edge mass-customization, and insights from treating 3 million-plus patients worldwide, Invisalign clear aligners provide a more comfortable and aesthetically appealing treatment option for various orthodontic issues.
