SANTA CLARA, Calif., April 30, 2009 /PRNewswire-FirstCall via COMTEX News Network/ -- Align Technology, Inc. (Nasdaq: ALGN) today announced an exciting company milestone: shipping its one millionth Invisalign case. There are now more than one million patients worldwide who have completed or are in treatment with the Invisalign system.

"This is a significant business milestone for us as it demonstrates continued, strong demand for Invisalign, which has evolved into a mainstream treatment option," said Thomas M. Prescott, president and CEO of Align Technology. "With more than a million Invisalign patients and counting, we're continuing to grow the market for clear aligner therapy and expand the Invisalign product family."

Earlier this month, Align shipped its one-millionth case to Dr. James Kohl of Wilmette, IL. A past president of the Illinois Society of Orthodontists, Dr. Kohl was one of the first doctors to embrace Invisalign in his practice. Last week, Dr. Kohl delivered the first set of Invisalign Teen(TM) aligners to the one-millionth patient, 15-year-old high school freshman Julia H.

"It's an honor to share this milestone with Align by treating the millionth patient," said Wilmette, Ill.-based orthodontist Dr. James Kohl. "Having prescribed Invisalign to many of my adult and teen patients over the years - from very complex to simple cases - I'm a huge believer in this product. It represents the future of orthodontics because it eliminates so many barriers to treatment, giving me an effective tool to delivering a beautiful smile to anyone - from adults that would never consider metal braces to active teens that don't want braces interrupting their busy lives."

Dr. Kohl is treating Julia H. with Invisalign Teen. Developed with leading orthodontists who understand the active lifestyles and unique treatment needs of teens, the new Invisalign Teen product combines the benefits of the proven Invisalign Full system with new features like blue Compliance Indicators that are designed to gradually fade as the aligner is worn, Eruption Tabs that accommodate the growth of secondary molars, and other features that address clinical needs common to teen patients.

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, Invisalign Express, and Vivera Retainers.
