Invisalign is a result of development of which retainer?

Explanation:
Clear, removable vacuum-formed Essix retainers provided the early concept of using nearly invisible plastic appliances to move teeth. Invisalign builds on that idea with a computer-planned sequence of custom aligners designed to progressively shift each tooth in small steps. The Hawley retainer is a traditional metal-and-acrylic design, not the origin of this invisible-aligner approach. The Herbst appliance is a functional bite-correcting device, not related to aligners. Vivera is the brand name for the Invisalign aligners themselves, not the original retainer concept. So the development Invisalign traces back to is the Essix retainer.
