Align Technology announces Invisalign interoperability with 3M True Definition Align Technology (ALGN) and 3M ESPE (MMM) announced that Align Technology has qualified the 3M True Definition scanner for use with Invisalign case submissions, which requires an intraoral scanner that can readily capture an accurate full arch digital impression. This qualification will now enable Invisalign providers with a True Definition scanner to submit a digital impression in place of a traditional PVS impression as part of the Invisalign case submission process. The 3M True Definition scanner is the only third-party scanner that has been qualified for use with Invisalign treatment. Align's own iTero scanner was qualified for Invisalign case submission in December 2011. Align supports an open systems approach to digital impressions and continues to work with intraoral scanning companies interested in developing interoperability for use with Invisalign treatment.
