        ALIGN TECHNOLOGY, INC. REPORTS Q3 2006 REVENUES OF $49.0 MILLION

Santa Clara, Calif. - October 25, 2006 - Align Technology, Inc. (Nasdaq: ALGN),
the inventor of Invisalign(R), a proprietary method of straightening teeth
without wires and brackets, today reported financial results for the third
quarter of 2006. Total revenues for the third quarter of 2006 were $49.0
million, compared to $50.9 million in the third quarter of 2005, a decrease of
3.6 percent.

"The third quarter was a busy one for Align," stated Thomas M. Prescott, Align
Technology's President and CEO. "Over 1,100 doctors used Invisalign for the
first time and we trained almost 1,000 new doctors. Additionally, at the end of
the quarter, we announced our intent to sign a definitive agreement with
OrthoClear - which we did earlier this month - ending all pending litigation
matters with them. With the litigation now behind us and our base of doctors
growing, we can focus entirely on growing the top line. We will generate that
growth through increased adoption of Invisalign by dentists and orthodontists as
the Invisalign product evolves to better meet their specific needs. Our goal is
to return to profitability and increase value for our shareholders, customers,
and employees."

The net loss for the third quarter of 2006, as reported on a GAAP basis, was
$10.3 million, or loss per share of $0.16. This compares to GAAP net loss of
$1.5 million for the third quarter of 2005, or loss per share of $0.02.

                     Tel: (408) 470-1000 Fax: (408) 470-1201

The non-GAAP net loss for the third quarter of 2006 was $8.0 million, or non-GAAP loss per share of $0.13. The reconciliation of the GAAP to non-GAAP measurements for net loss for the third quarter of 2006 is set forth below within Align Technology's financial statements. As of September 30, 2006, Align had $86.1 million in cash, cash equivalents, marketable securities, and restricted cash, compared to $74.4 million as of December 31, 2005. Align borrowed $15 million from its credit facility during the third quarter. Additionally, on October 13, 2006, Align signed the definitive agreement with OrthoClear and subsequently disbursed $20 million to them.

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 April 1997 and received FDA clearance to market Invisalign in 1998. To learn more about Invisalign or to find a certified Invisalign doctor in your area, please visit www.invisalign.com or call 1-800-INVISIBLE.

Forward-Looking Statement This news release contains forward-looking statements, including statements regarding Align's expectation that it will generate revenue growth through increased adoption of Invisalign by dentists and orthodontists by evolving the Invisalign system to better meet their specific needs. Forward-looking statements contained in this news release relating to expectations about future events or results are based upon information available to Align as of the date hereof. Readers are cautioned that these forward-looking statements are only predictions and are subject to risks, uncertainties and assumptions that are difficult to predict. As a result, actual results may differ materially and adversely from those expressed in any forward-looking statement. Factors that might cause such a difference include, but are not limited to, risks relating to Align's ability to sustain or increase profitability or revenue growth in future periods while controlling expenses, including expenses related to the OrthoClear settlement, customer demand for Invisalign, acceptance of Invisalign by consumers and dental professionals, Align's third party manufacturing processes and personnel, foreign operational, political and other risks relating to Align's international manufacturing operations, Align's ability to protect its intellectual property rights, competition from manufacturers of traditional braces and new competitors, Align's ability to develop and successfully introduce new products and product enhancements, and the loss of key personnel, including members of its direct sales force. These and other risks are detailed from time to time in Align's periodic reports filed with the Securities and Exchange Commission, including, but not limited to, its Annual Report on Form 10-K for the fiscal year ended December 31, 2005, which was filed with the Securities and Exchange Commission on March 1, 2006, and its Quarterly Reports on Form 10-Q.

ALIGN TECHNOLOGY, INC. NON-GAAP CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS (unaudited) USE OF NON-GAAP FINANCIAL INFORMATION To supplement our condensed consolidated financial statements presented on a GAAP basis, we use non-GAAP measures of gross profit, profit (loss) from operations, net profit (loss) and certain expenses (including sales and marketing, general and administrative and research and development), which exclude stock-based compensation to allow for a better comparison of results in the current period to those in prior periods that did not include FAS 123(R) stock-based compensation. We believe the non-GAAP measures that exclude stock-based compensation enhance the comparability of results against prior periods. In addition, we use these non-GAAP financial measures for internal management purposes, when publicly providing our business outlook and as a means to evaluate period-to-period comparisons. These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures prepared in accordance with GAAP.
