The Science Behind Invisalign

Prospective users of Invisalign usually have one question to start: how Invisalign works. The technology dates only to the 1990s, where it was founded under the manufacturer name Align. The founders believed in a more visual approach to orthodontic work, and figured out a push mechanism to contrast with the pull mechanism of traditional braces.

In terms of composition, Invisalign trays, or aligners, are mostly made of polyurethane—a medical-grade polymer, with a few additives thrown in. These combine to give the material its thinness, translucence, and strength.

Where braces are powered by rubber bands and archwires, the polyurethane Invisalign aligners apply pressure progressively. This means each set of aligners is designed to follow the one before it, with a new set replacing the old one at a predetermined rate—usually every two weeks. You must wear your aligners in the exact order specified by your Invisalign dentist in Los Angeles—the aligners come numbered to help you out.

Invisalign is primarily a straightener. Its science is directed at rotated, crowded, or unevenly spaced teeth that do not involve any deeper orthodontic issues. If you have any history of malocclusion, for example, your dentist may refer you to another orthodontist, or another product.

If all goes well, your teeth will be straight after about a year of service.
