Clear aligner: an efficient, esthetic, and comfortable option for an adult patient

Abstract

The Clear Aligner represents an easy way to treat orthodontic patients when a minor tooth movement is necessary (crowding or spacing less than 4 mm) or when relapse occurs during the retention phase. During the retention phase, the Clear Aligner acts as a passive retainer but it is activated if relapse occurs. The Clear Aligner is an esthetic, efficient, comfortable, and low-cost appliance. In this article, the authors explain the indications and limitations of the Clear Aligner, as well as the laboratory and clinical protocol.
