Functional clear aligner treatment of class Ⅱ malocclusion in teenagers

Abstract

Class Ⅱ malocclusion is a common orofacial deformity that could harm the facial esthetics and oral function. Two-stage treatment strategy always applies to functional and skeletal (mild and moderate) class Ⅱ malocclusion with man-dibular retrognathism in teenagers. Traditional functional orthopedic appliances are less comfortable and inconvenient to correct the dental arches, making the treatment duration long. With the rapid progress of digital technology and material science, functional clear aligners that offer comfort have emerged. Functional clear aligners can combine orthopedic and orthodontic treatments to correct the jaw relationship and align the dental arch, thereby shortening the treatment duration. This paper emphasizes the treatment key points, and clinical experience of using functional clear aligners.
