SANTA CLARA, Calif. and YOKOHAMA, Japan, Oct 11, 2005 /PRNewswire-FirstCall via COMTEX/ -- At the 64th Annual Meeting of the Japanese Orthodontic Society in Yokohama today, Align Technology, Inc. (Nasdaq: ALGN), the inventor of Invisalign(R), a proprietary method of straightening teeth without wires and brackets, announced the launch of Invisalign in Japan.

Next month Align will begin hosting certification courses for orthodontists in Japan, and will offer Japanese versions of VIP and ClinCheck(R). Doctors will receive significant post-certification support from local sales and clinical support personnel to assist through the initial learning curve with Invisalign.

"We are committed to launching Invisalign treatment in Japan in a measured, thoughtful manner," said Gil Laks, Align's Vice President, International. "Doing so will allow us to provide a significant level of clinical support for each doctor, and will help us reach our goal of building strong, evidence-based relationships with the orthodontic community in Japan. This is critical to maximizing the long-term market potential of the world's second largest economy."

"The Invisalign system clearly represents one of the advancing technologies in the field of orthodontics," said Dr. Koutaro Maki, Professor and Chair of Department of Orthodontics at Showa University in Tokyo. "Given the technological contributions the product is expected to make in Japanese orthodontics and the strong desire for aesthetic treatment by the patients in Japan, I believe the potential market for the product is significant with the appropriate usage by and support from the orthodontists in 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 older teens. Align Technology was founded in March 1997 and received FDA clearance to market Invisalign in 1998.
