                                                                    Exhibit 99.1


 U.S. District Court Finds Ormco Corporation's (a Division of Sybron Dental)
                               Patents Invalid

    SANTA CLARA, Calif., Aug. 26 /PRNewswire-FirstCall/ -- Align Technology,
Inc. (Nasdaq: ALGN), the inventor of the Invisalign(R) system, a proprietary
method of straightening teeth without wires and brackets, announced today that
the U.S. District Court has granted summary judgment in favor of Align
Technology, Inc.

    Ormco Corporation (a division of Sybron Dental Specialties, Inc.,
NYSE: SYD) sued Align in 2003 alleging infringement of four patents (Patent
Nos. 5,447,432, 5,683,243, 6,244,861 and 6,616,444).  The United States
District Court for the Central District, Southern Division, granted Align's
motion for summary judgment of invalidity of Ormco's patents (the Court ruled
earlier this year that Align does not infringe these patents). As Ormco's
patents were found invalid by the Court, this provides Align additional
freedom to operate in the field of digital dentistry. The Court also denied
Ormco's summary judgment motion seeking a finding of invalidity of Align's
patents (Patent Nos. 6,398,548 and 6,554,611).  Align is represented by
intellectual property specialty firm, Townsend and Townsend and Crew LLP.

    "This third summary judgment against Ormco is a testament to the lack of
any basis for Ormco's suit against us," said Thomas M. Prescott, President and
CEO of Align Technology, Inc. "We believe the successful defense of our
intellectual property, along with the more than fifty patents issued and
numerous patent applications pending will enable long-term value creation for
our shareholders. Align will continue to invest in the technology and
processes that make Invisalign an important part of our customers' practices
and the most attractive way for consumers to gain a better smile."

    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.
