| 摘 要： | 目的 观察活动舌弓 再曲簧临床扩弓效果,寻找一种简便、有效,尤其对下颌牙弓更理想的扩弓方法.方法 选择临床牙弓狭窄伴牙列轻度拥挤患者.其中上颌扩弓者9例,下颌扩弓者8例,随机分为两组,分别采用活动舌弓 再曲簧和四眼簧进行扩弓,比较两组的扩弓效果.结果 通过8周的扩弓治疗,活动舌弓组U4-U4及U5-U5间宽度分别平均扩大2.2 mm和3.0 mm,四眼簧组U4-U4及U5-U5间宽度平均扩大2.3 mm和3.5 mm,两处理组组间比较无显著性差异(P＞0.05).通过12周的扩弓治疗,活动舌弓组L4-L4及L5-L5间宽度分别平均扩大2.3 mm及2.5 mm,四眼簧组L4-L4及L5-L5间宽度平均扩大1.0 mm和1.2 mm,两处理组组间比较有显著性差异(P＜0.05).结论 活动舌弓 再曲簧可明显扩大牙弓中段(前磨牙区),尤对下颌牙弓的扩弓作用明显优于四眼簧.

| Abstract: | Objective Observe the clinical effect of removable lingual arch plus auxiliary spring for convenient dental (especially mandibular) arch expansion. Methods Seventeen patients with dental arch constriction complicated by mild dental crowding were enrolled in this study, including 9 requiring maxillary arch expansion and 8 necessitating mandibular expansion. The patients were divided to two groups at random for arch expansion with removable lingual arch plus auxiliary spring and with Quad-helix, respectively, and the effect of arch expansion was compared between the two groups. Results After 8 weeks of arch expansion, the average width of U4-U4 and U5-U5 in removable lingual arch group was enlarged by 2.2 mm and 3.0 mm, and that in Quad-helix group by 2.3 mm and 3.5 mm, respectively, showing no significant differences between the two groups (P>0.05). After 12 weeks of treatment, the average width of L4-L4 and L5-L5 in the former group was enlarged by 2.3 mm and 2.5 mm, respectively, significantly greater than that in the latter group (1.0 mm and 1.2 mm, P<0.05). Conclusion Removable lingual arch plus auxiliary spring allows significant expansion of the middle segment of the dental arch (bicuspids), and can be more effective than Quad-helix for mandibular arch expansion. |
