隐形功能矫治器矫治青少年Ⅱ类错畸形

Functional clear aligner treatment of class Ⅱ malocclusion in teenagers

Ⅱ类错[牙合]是一种常见的牙颌畸形,对青少年颜貌美观和口颌系统功能有明显的影响。对于青少年以下颌后缩为主的功能性和轻中度骨性Ⅱ类错[牙合],建议采用双期矫治。传统的功能矫治器舒适度低,不方便进行牙列的调整,疗程较长;随着数字化技术和材料科学的快速发展,隐形功能矫治器应运而生。隐形功能矫治器佩戴舒适,可以将矫形治疗和矫治治疗有机地结合在一起,在调整颌骨关系的同时对错位牙进行矫正,提高矫治效率,缩短治疗时间。本文结合典型病例,简单介绍使用隐形功能矫治器矫治青少年Ⅱ类错[牙合]畸形的矫治要点和治疗体会。

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.
