The aim of this study was to evaluate the vertical skeletal and dentoalveolar changes in the Class II Division 1 cases treated with the activator + occipital headgear combination. The present study was performed on 40 subjects and comprised 20 subjects who had undergone activator + occipital headgear therapy and 20 control subjects who had received no orthodontic treatment. 15 linear and angular measurements were performed on 80 lateral cephalometric films of 40 subjects. By comparing the treatment and control groups, the changes related to growth was eliminated and following results were obtained: SNA and ANB angles were reduced in treatment group (p less than 0.01) and the difference between treatment and control groups were statistically significant (p less than 0.01). Jarabak ratio did not show any change in the treatment group but decreased in the control group (p less than 0.05) and the difference between treatment and control groups was statistically significant (p less than 0.05). The growth of lower anterior alveolar height was inhibited by treatment when compared to control group (p less than 0.01).
本研究的目的是评估使用肌激动器+枕部牵引矫治器联合治疗的安氏II类1分类病例的垂直骨骼及牙牙槽变化。本研究对40名受试者进行，其中包括20名接受过肌激动器+枕部牵引矫治器治疗的受试者以及20名未接受过正畸治疗的对照受试者。对40名受试者的80张头颅侧位片进行了15项线性和角度测量。通过比较治疗组和对照组，消除了与生长相关的变化，得到以下结果：治疗组的SNA角和ANB角减小（p<0.01），治疗组与对照组之间的差异具有统计学意义（p<0.01）。治疗组的贾氏比率未显示任何变化，但对照组的贾氏比率降低（p<0.05），治疗组与对照组之间的差异具有统计学意义（p<0.05）。与对照组相比，治疗抑制了下前牙槽高度的生长（p<0.01）。
