MATERIAL AND METHODS: Lateral head films of 16 consecutively-treated adult Class II, Division 2 subjects (8 males, 8 females) with an average age of 18.8 years pre-treatment were analyzed on three occasions: before treatment (T1), after Herbst-MB treatment (T2) and 2 years post-treatment (T3). RESULTS: Treatment period (T2-T1): an increase occurred in the hard tissue profile angle (2.5 degrees; p < 0.001), the soft tissue profile angle excluding the nose (2.6 degrees ; p < 0.01), and the soft tissue profile angle including the nose (1.8 degrees; p < 0.05). The upper lip became more retrusive in relation to the Esthetic line (EL) (0.8 mm; p < 0.05) while the lower lip~s position was unchanged. Lower lip coverage of the upper incisors was reduced (0.8 mm; p < 0.05). Post-treatment period (T3-T2): the soft tissue profile angle (excluding the nose) increased (1.6 degrees; p < 0.01), while the hard and soft tissue profile angles including the nose remained unchanged. Both, the upper and lower lips became more retrusive in relation to the EL (0.9 mm; p < 0.01 and 1.0 mm; p < 0.001). The lower lip coverage of the upper incisors remained unchanged. CONCLUSION: The hard and soft tissue profiles were straightened during Herbst-MB treatment, including a brief follow-up period. The lips became more retrusive while the lower lip coverage of the upper incisors was reduced. ------>tmu_sno=None ------>sno=1444 ------>authors2=None ------>authors3=None ------>authors4=None ------>authors5=None ------>authors6=None ------>authors6_c=None ------>authors=Cheng H-C, Chen C-F, Chao W-H, Tsai C-Y ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=None ------>publish_area=None ------>updateTitle=Facial profile and lip position changes in adult Class II, Division 2 subjects treated with the Herbst-Multibracket appliance.
