摘要： 目的:探讨磨牙牵引器在双侧下第二磨牙阻生矫正中的应用。方法:选择5例双侧下第二磨牙阻生,术前拔除下颌第三磨牙,然后分别戴用个性化制造的磨牙牵引器对患牙进行矫正。结果:所有病例的患牙皆得到了扶正,平均疗程7个月,右下第二磨牙牙体长轴倾斜角的矫正平均值为49.6°,左下第二磨牙牙体长轴倾斜角的矫正平均值为45.4°。结论:磨牙牵引器可以有效地矫正双侧下第二磨牙阻生。

Abstract: Objective: To investigate the application of molar retractor in the correction of bilateral impacted mandibular second molars and observe the clinical effects. Methods: The case group consisted 5 patients with bilateral impacted mandibular molars. All mandibular third molars had been extracted before treatment. Molar retractors were manufactured and used in these patients. The clinical effects were observed and evaluated. Results: All the impacted second molars had been corrected successfully. The average period of treatment was 7 months. The mean change value of the inclination of the right mandibular impacted molars was 49.60° and that of the left mandibular impacted molars was 45.40°. Conclusion: Molar retractor effectively corrected the bilateral impacted mandibular second molars and could enable orthodontist to upright the impacted molars rapidly.
