What are the second-class traction side effects of orthodontics? Will it make your mouth retract?

Classmate, the purpose of the second-class traction is to guide the mandible to move forward, correct the mental retraction of the second-class patients or adjust the molar relationship of the mandibular molars, so as to move the molars forward and adjust the overbite of the anterior teeth. However, its side effect is that the lower molars are elongated, so patients with high angles should use it with caution! Then when traction is hung, the maxillary anterior teeth will rotate clockwise to a certain extent, but they will not shrink!
