Adolescents with skeletal class Ⅱ malocclusion are frequently seen in orthodontic departments, with a high occurrence rate and significant effects on both appearance and function. Maxillary protrusion and mandibular retrusion are frequently demonstrated in skeletal class Ⅱ malocclusion. Most experts agree that the ideal period to correct mandibular retraction is an adolescent growth spurt. With the rapid development of clear aligner technology, functional clear aligner technology has emerged, which combines the traditional two-stage orthodontic corrections into one, and helps expand the scope of Invisalign. It can align the teeth and coordinate dental arches while guiding the mandible forward, reduce orthodontic time, and greatly improve orthodontic efficiency. This article aimed to explore the growth and development characteristics as well as the features of clear aligners in the treatment of teenagers with skeletal classⅡ malocclusion.
