AIM
The aim of the present study was to evaluate the cephalometric changes in growing Class II patients with increased vertical dimension treated with cervical or high-pull headgear, by using an untreated control group with similar skeletal characteristics.
MATERIALS
From the initial sample, 56 patients satisfied the inclusion and exclusion criteria; 20 patients were treated with cervical headgear (CHG), 15 with high-pull headgear (HHG), and 21 were not treated (CG). Cephalograms were available for each subject at baseline (T1) and after treatment/observation time (T2) for the three groups. A total of 17 measurements were taken on the lateral head films. Group comparison among CHG, HHG and CG was done using ANOVA test.
CONCLUSION
In Class II high-angle growing patients, cervical headgear seems to be preferred in the correction of maxillary protrusion, molar relationship and increased anterior facial height. Extrusion of the upper molar may favour forward repositioning of the mandible and clockwise rotation in Class II patients with increased vertical dimension.
目的
本研究旨在通过未治疗的具有相似骨骼特征的对照组，评估颈椎或高牵引头帽治疗生长中安氏Ⅱ类高角患者垂直向增加时的头影测量变化。
材料
从初始样本中，有 56 名患者符合纳入和排除标准；20 名患者接受颈椎头帽（CHG）治疗，15 名患者接受高牵引头帽（HHG）治疗，21 名患者未治疗（CG）。三组患者在基线（T1）和治疗/观察时间（T2）时均有侧头部影片。在 T1 和 T2 时对 17 个测量项目进行测量。使用方差分析（ANOVA）检验对 CHG、HHG 和 CG 三组进行组间比较。
结论
在生长的安氏Ⅱ类高角患者中，颈椎头帽似乎更适合矫正上颌前突、磨牙关系和增加前面部高度。在上颌磨牙外倾的情况下，对于垂直向增加的安氏Ⅱ类患者，下颌可能会向前重新定位并顺时针旋转。
