Effect of orthodontic bracket thickness on degree of patient's comfort after initial orthodontic bracket placement

目的:比较初戴超薄正畸托槽和普通托槽对成年患者牙齿、口腔黏膜以及对睡眠情况的影响,为临床应用提供参考。方法:选择固定正畸治疗的成年患者60例,随机分成2组,超薄托槽组和普通托槽组,对戴用固定矫治器后7d内患者的牙齿疼痛程度,口腔溃疡的发生率及发生部位,口腔不适程度以及疼痛对睡眠的影响进行问卷调查,并进行对比分析。结果:回收有效问卷60份,有效回收率100%。各组均2h左右开始出现牙齿酸痛,第7d牙齿基本恢复到正常水平。超薄组与传统组病人在初戴矫治器7天内牙齿疼痛强度,溃疡发生率,口腔不适度,对睡眠的影响等比较差异无统计学意义(P>0.05)。结论:正畸患者使用超薄托槽与普通托槽后牙齿与黏膜的不适与疼痛症状差异无统计学意义。
