Clear aligners are a series of custom-made, removable, transparent plastic trays that incrementally move teeth into the desired position. Patients receive a new set every one to two weeks. Treatment is planned digitally using 3D scans, allowing patients to preview their final result. Clear aligners have become the fastest-growing orthodontic treatment globally, popular for their near-invisible appearance and convenience.
