Thomas M. Prescott, president and chief executive officer of Align Technology Inc, is scheduled to speak about three new Invisalign products today at the annual JPMorgan Healthcare Conference in San Francisco. A live Web cast may be accessed via Align Technology’s Investor Relations Web site at investor.aligntech.com. The presentation will take place 2:30 to 2:55 PM Eastern Time (corrected time). The Breakout will take place at 3:00 to 3:25 PM Eastern Time (corrected time). An archived replay will remain on the Web site for the next 3 months.

The three products, Vivera Retainers, Invisalign Teen, and Invisalign ClinAssist are expected to streamline an orthodontic practice to help practitioners plan and manage cases more efficiently.

"For the past two years we have focused on Align’s long-term strategy and the opportunity we have to further penetrate our market through product innovation," said Thomas M. Prescott, Align Technology’s president and chief executive officer. "This is the year our product development strategy is coming to life. 2008 marks a new direction in the way Align develops and delivers the technology, clinical expertise, and benefits of the Invisalign system to our customers and their patients. New products that are designed to increase utilization and overcome barriers to greater adoption are now in pilot, and we are excited about previewing those offerings at the JPMorgan Healthcare Conference today."

Vivera retainers are a long-term retention product designed for patients who wear and do not wear Invisalign. Vivera retainers are shipped directly to patients or to the treating practitioner four times each year through an annual subscription program. Unlike traditional clear retainers, Vivera retainers are made with the same technology as Invisalign aligners, which provide a comfortable fit. Vivera’s thermoplastic material is more than 30% stronger than other clear retainer materials. Vivera Retainers are available now through Invisalign doctors in North America.

Invisalign Teen is designed to meet the needs of teenagers. It features an aligner wear indicator to help gauge patient compliance. The aligner addresses the natural eruption of key teeth and root control issues common in patients between the ages of 13 and 19. Three free replacement aligners can be shipped during active treatment to cover potential aligner loss. Invisalign Teen is scheduled to be released later this year.

Invisalign ClinAssist is designed as a consultative device for practitioners who want an efficient treatment process with built-in monitoring tools and progress checks. Its features include a simplified submission process, case monitoring support by Align Technology to help orthodontists keep cases on track, and staged shipment of aligners based on the treatment progress. Invisalign ClinAssist will be available later this year or in early 2009.
