Santa Clara, Calif. - January 9, 2005 - Align Technology, Inc. (Nasdaq: ALGN),

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.
