隐形功能矫治器矫治青少年Ⅱ类错畸形

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 mandibular 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.
