Invisalign® is a custom-made aligner that is interchanged roughly every two weeks for a period of six to eighteen months, or longer depending on the severity of misalignment.
Similar to a mouth or dental retainer (which is designed to keep teeth from shifting out of place), an Invisalign® aligner is used for orthodontic treatment as a technique to move and properly align teeth for a beautiful smile.
This clear aligner is usually computer generated from a mold (or impression) of the patient’s teeth—taken by either a dentist or an orthodontist—and the fitting is unique to each patient only.
Dr Mark Hughes, an expert cosmetic dentist, explains exactly how Invisalign work.
