ABSTRACT
<p><b>OBJECTIVE</b>To assess the effectiveness of vertical control with high-pull headgear in the treatment of high angle cases.</p><p><b>METHODS</b>Forty high angle cases (MP-SN >40 degrees) were included in this study and all the patients were treated with extraction. Twenty patients in the study group and control group, respectively. Totally 14 cephalometric measurements were selected for the assessment Paired t-test and independent t-test were used in the analysis.</p><p><b>RESULTS</b>No significant differences were found between the two groups (P > 0.05). In the study group, after treatment Y angle, MP-SN angle, MP-FH angle and U6-PP distance increased 1.9 degrees, 1.5 degrees, 2.3 degrees and 1.1 mm, respectively (P < 0.01).</p><p><b>CONCLUSIONS</b>High-pull headgear could not provide effective vertical control in high angle cases.</p>
