Invisalign

Abstract

Orthodontic developments, especially during the last few years have been accompanied by a significant increase in the esthetic demands of the patients. As the demand for esthetic treatments is increasing, more people are seeking alternatives to fixed orthodontic appliances. Clear aligners provide an excellent solution as compared to fixed orthodontic appliances in terms of esthetics and comfort to the patient. In 1998, Align Technology (Santa Clara, Calif, USA) introduced Invisalign, a series of removable polyurethane aligners, as an esthetic alternative to fixed orthodontic appliances
