SANTA CLARA, California, March 2 /PRNewswire/ --

Align Technology, Inc. (Nasdaq: ALGN) today announced the international availability of Invisalign Teen(TM) for non-adult, comprehensive orthodontic treatment. Invisalign Teen is based on the innovative technology and demonstrated effectiveness of the Invisalign(R) system, with new features to address patient compliance, natural eruption of permanent teeth, and root-movement control - issues that are common in treatment of younger patients. Invisalign Teen was launched in the U.S. and Canada in July 2008.

We are pleased to offer Invisalign Teen to our customers in key markets around the world, said Gil Laks, Align Technology vice president, international. The addition of Invisalign Teen to our product portfolio will allow doctors to extend the benefits of Invisalign treatment to more of their patients and offer a more comprehensive solution that meets the needs, activities and lifestyle of today's teenagers.

Invisalign providers like Dr. Werner Schupp, an Invisalign Platinum Elite doctor practicing in Europe, see Invisalign Teen as a 21st century treatment option for an increasingly discerning patient group: Invisalign Teen is a great way for me to offer a clinical and aesthetic alternative treatment to my teenage patients. As today's teenagers become increasingly more demanding, better informed, and more empowered to make their own decisions, I am finding more and more that Invisalign is the treatment they want.

With Invisalign Teen, teenagers get clear, removable aligners that meet their desire for aesthetic treatment and their need for appliances that fit their busy schedules of sports, music and other activities. Invisalign doctors see additional benefits to Invisalign Teen's removable aligners. Invisalign Teen meets the needs of this patient group effectively and can also greatly reduce the issues we see with traditional fixed appliances such as broken wires and brackets and poor oral hygiene, said Dr. Schupp. With Invisalign Teen, patients can brush and floss more effectively, thus helping reduce the risk of decalcification and increase the level of their overall oral health.

Invisalign Teen is available through Invisalign-trained doctors world-wide, with the exception of Japan.

About Align Technology, Inc.

Align Technology designs, manufactures and markets Invisalign, a proprietary method for treating malocclusion, or the misalignment of teeth. Invisalign corrects malocclusion using a series of clear, nearly invisible, removable appliances that gently move teeth to a desired final position. Because it does not rely on the use of metal or ceramic brackets and wires, Invisalign significantly reduces the aesthetic and other limitations associated with braces. Invisalign is appropriate for treating adults and teens. Align Technology was founded in March 1997 and received FDA clearance to market Invisalign in 1998. Today, the Invisalign product family includes Invisalign, Invisalign Teen, Invisalign Assist(TM), Invisalign Express(TM), and Vivera(TM) retainers.
