The aim of this study was to evaluate the early treatment of atypical deglutition, by analysing the efficacy of the eruptive guide appliance Habit Corrector™.
The pre- and post-treatment (T1 and T2) cephalometric data of 2 groups of patients (G1 and G2), both consisting of 25 patients each and treated with Habit Corrector™, were compared. The first group included 10 males and 15 females, aged between 4 and 7 years old, with average age 6.17 years, and therefore undergoing the last phase of primary dentition and the first phase of mixed dentition. The second group included 12 males and 13 females, aged between 8 and 12 years old, with average age 9.19 years old, undergoing the second phase of mixed dentition. The overall duration of the treatment was 12 months.
The results showed significant differences between the two groups, with respect to overbite, overjet, molar relation, inclination of the upper and lower incisors, position of the jaw. A significant variation between the two groups at T2 was registered for the maxillomandibular relationships: the increase in the growth and degree of mandibular protrusion was of 4.66° in G1 and 2.44° in G2. Significant changes were registered for the position or growth of the upper jaw; the upper facial height almost remained unaltered, with 53.34° for G1 and with 53.96° for G2. A significant variation occurred with the increase in the sagittal relationship between the molars, improved in G1 by 3.14 mm and in G2 by 2.61 mm. A significant decrease of overjet was registered in G1 by 1.94 mm and in G2 by 0.76 m and an increase of overbite in G1 by 3.14 mm and in G2 by 0.88 mm. The inclination of the maxillary and mandibular incisors improved, with an inter-incisive angle of 123° in G1 and 124.2° in G2.
The clinical results obtained suggest that early intervention in atypical deglutition with Habit Corrector™ is able to produce significant results in primary dentition and in the first phase of mixed dentition, rather than in the late phase of mixed dentition.
本研究旨在通过分析 Habit CorrectorTM （爆发引导矫治器）的疗效，评估对非典型吞咽的早期治疗效果。
对比两组接受 Habit CorrectorTM 治疗的患者（G1 和 G2）的治疗前后（T1 和 T2）头影测量数据。第一组包括 10 名男性和 15 名女性，年龄 4 至 7 岁，平均年龄 6.17 岁，处于乳牙晚期和混合牙列早期。第二组包括 12 名男性和 13 名女性，年龄 8 至 12 岁，平均年龄 9.19 岁，处于混合牙列二期。治疗总时长为 12 个月。
两组的各项结果均存在显著差异，包括覆颌、覆盖、磨牙关系、上下切牙倾斜度、颌骨位置等。T2 时，两组的颌骨关系也有显著变化：G1 组的下颌生长和前突程度增加了 4.66°，G2 组则增加了 2.44°。上颌位置或生长也发生了显著变化；上颜面高度基本不变，G1 组为 53.34°，G2 组为 53.96°。磨牙矢状关系也有显著改善，G1 组增加了 3.14mm，G2 组增加了 2.61mm。G1 组的覆盖深度减少了 1.94mm，G2 组减少了 0.76mm，覆颌深度增加了 3.14mm，G2 组增加了 0.88mm。上颌和下颌切牙的倾斜度有所改善，G1 组的切牙交角为 123°，G2 组为 124.2°。
临床结果表明，在乳牙晚期和混合牙列早期而非混合牙列晚期，使用 Habit CorrectorTM 对非典型吞咽进行早期干预，可以取得显著效果。
