A material called Vinyl Polysiloxane is used to take impressions of the teeth. This material is used by being loaded into a tray, placed in the mouth and then setting (usually 1-2 minutes). This impression is sent to the Invisalign manufacturing facility and scanned (CAD/CAM) to make the aligners. The process takes around a month.
