How does the Invisalign appliance work?
The orthodontist or dentist most often acquires a digital scan of your teeth and then digitally moves your teeth to their ideal position. From there, the software simulates movement of the teeth based on a determined algorithm. The software then renders multiple digital models that simulate these movements. The digital models are printed and utilized to fabricate the aligners. As for the Invisalign appliance, the majority of this workflow is done at an industry scale level with robots in a few centers across the globe (Costa Rica, China, and Germany).
