Purpose: The aim of the present study was to investigate the cephalometric changes in patients with increased vertical dimension after treatment with cervical headgear compared to controls. Methods: The sample of the present retrospective study consisted of 20 Class II patients (10Â males, 10 females; mean age 8.54Â Â±Â 1.15Â years) with increased vertical dimension treated with cervical headgear (treatment group) and 21 Class II patients (11Â males, 10 females; mean age 8.41Â Â±Â 1.15Â years) with increased vertical dimension who underwent no treatment (control group). Cephalograms were available for each subject at baseline (T1) and after treatment/observation time (T2) for both groups and cephalometric analysis allowed for evaluation of changes between time points and between groups. Results: Regarding facial axis, N-ANS/ANS-Me, and overbite, there were no negatively significant changes in the treated group showing no significant worsening in the vertical dimension. Regarding facial angle, there was a significant increase in the treated group between the time points and when compared to the control group, showing counterclockwise rotation of the mandible in the treated group. Conclusions: The vertical dimension was not significantly altered after cervical headgear treatment although the anterior facial height was higher at the beginning of treatment. There was significant counterclockwise rotation of the mandible, and clockwise rotation and distal displacement of the maxilla after treatment.
