(Nasdaq: ALGN ) today announced that its initial public offering of 10,000,000 shares of common stock has been priced at $13.00 per share. All of the shares are being offered by the company.

Align Technology designs, manufactures and markets the Invisalign^® System, a proprietary new method for treating malocclusion, or the misalignment of teeth. The Invisalign System 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, the Invisalign System significantly reduces the aesthetic and other limitations associated with braces.
