Background

The purpose of this clinical study was to assess the effects of different rapid maxillary expansion appliances on the severity of obstructive sleep apnea (OSA).

Material and methods

Patients having a narrow maxilla and identified with OSA were divided randomly into three groups: tooth tissue-borne, tooth-borne, and bone-borne expanders. Changes in sleep parameters at baseline and 3-month follow-up detected by polygraphy were the primary outcome. Treatment of the crossbite was the secondary outcome. Dunn-Bonferroni tests, Kruskal–Wallis, and Wilcoxon analysis were applied for intra- and inter-group differences at p < 0.05 significance level.

Results

Among 46 patients randomized, apnea-hypopnea index (AHI) changed from baseline to follow-up in all groups (− 1.6, p = 0.280; 0.6, p = 0.691; − 0.45, p = 0.796, respectively), with no between-group difference (p = 0.631). Oxygen desaturation index (ODI) altered from baseline to follow-up in all groups (0.80, p = 0.977; 0.20, p = 0.932; and − 1.00, p = 0.379, respectively), with no between-group difference (p = 0.858). There was no significant difference in minimum oxygen saturation from baseline to follow-up in all groups (0.00, p = 0.401; − 2.00, p = 0.887; 0.50, p = 0.407, respectively). No significant changes were observed in supine AHI from baseline to follow-up in all groups (0.00, p = 0.581; − 1.00, p = 0.393; 0.00, p = 0.972, respectively). The upper intermolar width increased from baseline to follow-up in all groups (5.04, p = 0.000; 3.15, p = 0.001; 5.41, p = 0.00, respectively) with no between-group difference (p = 0.560). Maxillary width increased from baseline to follow-up in all groups (4.25, p = 0.001; 4.74, p = 0.00; 4.49, p = 0.001, respectively) with no inter-group difference (p = 0.963).

Conclusions

The amount of skeletal and dental expansion obtained in the maxilla was similar in all groups. Rapid maxillary expansion was not found to be effective in OSA treatment.

不同上颌骨快速扩弓矫治器对睡眠质量影响的多图评价：一项随机临床试验

背景

本临床研究的目的是评估不同快速上颌扩弓矫治器对阻塞性睡眠呼吸暂停 (OSA) 严重程度的影响。

材料与方法

上颌骨狭窄并被确定为 OSA 的患者被随机分为三组：牙齿组织携带、牙齿携带和骨携带扩张器。主要结果是基线时睡眠参数的变化和 3 个月随访时通过测谎仪检测到的变化。反咬合的治疗是次要结果。Dunn-Bonferroni 检验、Kruskal-Wallis 和 Wilcoxon 分析应用于p < 0.05 显着性水平的组内和组间差异。

结果

在 46 名随机分组的患者中，所有组的呼吸暂停低通气指数 (AHI) 从基线到随访都有变化（分别为 − 1.6，p = 0.280；0.6，p = 0.691；− 0.45，p = 0.796），两者之间没有差异组差异 ( p = 0.631)。所有组的氧饱和度指数 (ODI) 从基线到随访都有变化（分别为 0.80，p = 0.977；0.20，p = 0.932；和 - 1.00，p = 0.379），没有组间差异（p = 0.858） ). 所有组的最低氧饱和度从基线到随访无显着差异（0.00，p = 0.401；- 2.00，p = 0.887；0.50，p = 0.407，分别）。从基线到随访，所有组的仰卧 AHI 均未观察到显着变化（分别为 0.00，p = 0.581；- 1.00，p = 0.393；0.00，p = 0.972）。所有组的上磨牙间宽度从基线到随访增加（分别为 5.04，p = 0.000；3.15，p = 0.001；5.41，p = 0.00），无组间差异（p = 0.560）。所有组的上颌骨宽度从基线到随访均有所增加（分别为 4.25，p = 0.001；4.74，p = 0.00；4.49，p = 0.001），无组间差异 ( p = 0.963)。
