Santa Clara, Calif., Mar. 12, 2002 - Align Technology, Inc. (Nasdaq: ALGN), the inventor of Invisalign^®, a method of straightening teeth without wires and brackets, today announced that it has recently received two key industry awards for the design and production of Invisalign.

The first award, presented by Canon Communications LLC, is the 2002 Medical Design Excellence Award (MDEA) awarded to Align for Invisalign - a method of straightening teeth that employs the Company's computer-based, three-dimensional clinical model of treatment and clear, removable Aligners that gradually move teeth to a desired final position. The MDEA contest is the only awards program devoted exclusively to recognizing contributions and advances in the design of medical products. MDEA-winning products excel in the areas of product innovation, design and engineering excellence, end-user and patient benefits, and cost-effectiveness in manufacturing and healthcare delivery. Align's Invisalign is one of only three MDEA winners selected for excellence in the 2002 Dental Instruments, Equipment and Supplies category.

The second award is the 2001 3D Systems North American Stereolithography Excellence Award, presented to Align for its innovative use of stereolithography technology in the manufacturing of Invisalign. Align uses stereolithography technology, and machines manufactured by 3D Systems, to create Invisalign Aligners from digital input. Each year 3D Systems Corporation Users Group organization presents the Excellence Awards for the most outstanding work in stereolithography. This year the grand winner is Align Technology.

"Align employees are dedicated to finding ways of using technology to mass-produce a customized product that is clinically compelling and profitable for doctors to use, and desirable for consumers to wear. These awards are evidence of our employees' efforts, and I'm pleased to see Invisalign get recognition from both the medical and technology communities," said Zia Chishti, chief executive officer at Align Technology, Inc.

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, comfortable and 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 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.
