Invisalign clear aligners work the same way traditional braces do: by applying carefully controlled forces to teeth to move them into a better position. But they are not made of metal; instead, they are made of clear, flexible plastic.

Clear aligners are orthodontic devices that are a transparent, plastic form of dental braces used to adjust teeth. Clear aligners. An Invisalign aligner.

Most aligners are made of a plastic called polymethyl methacrylate (PMMA). PMMA is also used to make Plexiglas, acrylics, synthetic gems, and lenses. It's transparent, durable, and strong. Some aligners are made of polyethersulfone (PES), which is often used in food containers.

Nowadays, the material used to manufacture the aligners are polyethylene terephthalate glycol (PeT-G), polypropylene (PP), polycarbonate (PC), thermoplastic polyurethanes (TPU), ethylene-vinyl acetate (EVA) and many more (Lombardo et al., 2015).

How do aligners work? Aligners are designed to make small movements at a time by putting gentle pressure on your teeth. That pressure is transferred through your roots to your jaws. Your jawbone responds to forces by essentially moving the sockets, and your teeth go along for the ride.

The basic constituent polymeric component of transparent trays, including clear aligners, is polyurethane, which is not an inert material [8].
