The objective of this study was to evaluate the facial profile changes of patients treated for class II skeletal malocclusions with an elastodontic appliance compared to those treated with the Herbst appliance and a control group. Forty class II patients were treated using an elastodontic appliance (Group EA) and were compared to 40 patients treated with the Herbst appliance (Group H) and to 40 untreated class II children (Group C). Aesthetic profile variables were analysed using Arnett's analysis. Cephalograms were compared pre-treatment (T0) and post-treatment (T1). The Wilcoxon signed-rank test or paired-samples -test was used for pairwise comparison of cephalometric measurements taken at T0 and T1. One-way ANOVA and Tukey's post hoc test were performed to assess differences between the groups. In the elastodontic group, the inclination of the upper incisors increased by 4.05°. In addition, the Pog-TVL and B-TVL distances decreased by 2.84 mm and 1.79 mm, respectively. In patients treated with an elastodontic appliance, the inclination of the upper incisors increased by 4.05°. In addition, the Pog-TVL and B-TVL distances decreased by 2.84 mm and 1.79 mm, respectively. In patients treated with the Herbst appliance, the inclination of the lower incisors increased by 6.11°. Furthermore, the treatment resulted in reductions in the Pog-TVL distance (2.58 mm), the B-TVL distance (2.26 mm), and the LL-TVL distance (2.31 mm). The profile changes achieved by both devices are favourable for correcting class II skeletal malocclusion.
本研究的目的是评估与使用Herbst矫治器治疗的患者以及对照组相比,使用弹性正畸矫治器治疗II类骨性错牙合患者的面部轮廓变化。40名II类患者使用弹性正畸矫治器进行治疗(EA组),并与40名使用Herbst矫治器治疗的患者(H组)以及40名未经治疗的II类儿童(C组)进行比较。使用阿内特分析法分析美学轮廓变量。在治疗前(T0)和治疗后(T1)对头颅侧位片进行比较。采用Wilcoxon符号秩检验或配对样本t检验对T0和T1时的头影测量值进行两两比较。进行单因素方差分析和Tukey事后检验以评估组间差异。在弹性正畸组中,上切牙倾斜度增加了4.05°。此外,Pog-TVL和B-TVL距离分别减少了2.84 mm和1.79 mm。在使用弹性正畸矫治器治疗的患者中,上切牙倾斜度增加了4.05°。此外,Pog-TVL和B-TVL距离分别减少了2.84 mm和1.79 mm。在使用Herbst矫治器治疗的患者中,下切牙倾斜度增加了6.11°。此外,治疗导致Pog-TVL距离(2.58 mm)、B-TVL距离(2.26 mm)和LL-TVL距离(2.31 mm)减小。两种矫治器实现的轮廓变化均有利于纠正II类骨性错牙合。
