About Align Technology, Inc.

Align Technology designs, manufactures and markets Invisalign, a proprietary new 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.
