Summary

This study aimed to evaluate the changes in mandibular and cervical soft tissues in Class II patients with mandibular retrognathia treated with the Twin Block appliance, compared to skeletal Class I patients without functional treatment, using profile photographs and cephalometric films. Sixteen patients with Class II Division 1, fifteen with Class II Division 2, and fifteen with skeletal Class I malocclusion were included. Measurements were performed at the beginning of treatment and after functional therapy. In the Class II Div 1 group, most parameters showed significant reductions, except for neck length and jaw tip contour. In the Class II Div 2 group, only the Sm-E plane measurement remained unchanged, while the control group showed minimal changes. Between-group comparisons indicated significant improvements in cervicomental angle, lip-jaw-throat angle, and other lower face soft tissue parameters, especially in Class II Division 1 patients. The findings suggest that Twin Block therapy effectively improves both skeletal and soft tissue profiles, with more pronounced soft tissue enhancement in Class II Division 1 cases.
