Abstract

OBJECTIVE

Evaluate dental and skeletal changes resulting from the exclusive use of the cervical headgear for 15 ± 4 months in the treatment of patients with Class II division 1 malocclusion.

METHODS

Differences between the beginning (T1) and immediately after the end of the therapy (T2) with the cervical headgear in growing patients (Experimental Group, EG, n = 23) were examined and compared, during compatible periods, with those presented by a group of untreated individuals (Control Group, CG, n =22) with similar malocclusions and chronological age. The cephalometric variables evaluated were: ANB, GoGn.SN, AO-BO, S'-ANS, S'-A, S'-B, S'-Pog and S'-U6 (maxillary first molar). The Shapiro-Wilk and Levene tests were used to evaluate the results.

RESULTS

Significant differences were found relative to the ANB, S'-U6, AO-BO, S'-ANS, S'-A, S'-B and S'-Pog variables between T1 and T2 when comparing both groups. No statistically significant variation was found regarding the GoGn.SN angle.

CONCLUSIONS

The use of cervical headgear promoted distal movement of the maxillary first molars and restricted the anterior displacement of the maxilla, without significantly affecting the GoGn.SN angle.

摘要

目的

评估在治疗安氏II类1分类错牙合患者时，仅使用颈带矫治器15±4个月所导致的牙齿和骨骼变化。

方法

对生长发育期患者（实验组，EG，n = 23）使用颈带矫治器治疗开始时（T1）和治疗结束后即刻（T2）的差异进行检查和比较，并在相应时间段内与一组具有相似错牙合情况和实际年龄的未治疗个体（对照组，CG，n = 22）的情况进行比较。评估的头影测量变量包括：ANB、GoGn.SN、AO - BO、S'-ANS、S'-A、S'-B、S'-Pog和S'-U6（上颌第一磨牙）。采用Shapiro - Wilk检验和Levene检验来评估结果。

结果

两组比较时，T1和T2之间在ANB、S'-U6、AO - BO、S'-ANS、S'-A、S'-B和S'-Pog变量上存在显著差异。GoGn.SN角未发现有统计学意义的变化。

结论

使用颈带矫治器促进了上颌第一磨牙的远中移动，并限制了上颌的前向移位，而未对GoGn.SN角产生显著影响。
