Abstract

OBJECTIVE

To investigate the effects of maxillary orthodontic expansion on the alveolar bone tissue in adult patients treated with aligners by using cone-beam computed tomography.

METHODS

Thirty patients (22 females and 8 males; mean age: 36.3 years) were treated with Invisalign aligners. Cone-beam computed tomography and digital models were obtained before (T0) and after (T1) upper arch expansion. The bone thicknesses in the cervical, middle, and apical areas of the incisors, canines, premolar, and first molars were buccally and palatally measured, totaling 96 areas and 2,880 measurements. The buccolingual inclinations and transverse measurements of the teeth were obtained from digital models to correlate them with the bone changes. The statistical tests used were Student's -test, analysis of variance, and Pearson's correlation tests ( < 0.05).

RESULTS

From the 96 areas evaluated, 84 revealed an increase or stability in the alveolar bone thickness and twelve displayed significant bone loss. Bone changes did not correlate with the tooth inclination and transverse measurements.

CONCLUSIONS

Within the limitation of the present study, mild levels of upper arch expansion obtained with Invisalign aligners in adult patients did not result in any clinically significant loss of alveolar bone thickness.

摘要

目的

通过锥形束计算机断层扫描研究上颌正畸扩弓对成年隐形矫治患者牙槽骨组织的影响。

方法

30例患者（22例女性，8例男性；平均年龄：36.3岁）接受隐适美隐形矫治器治疗。在上颌扩弓前（T0）和扩弓后（T1）获取锥形束计算机断层扫描图像和数字模型。测量切牙、尖牙、前磨牙和第一磨牙颊侧和腭侧颈部、中部和根尖区的骨厚度，共96个区域，2880次测量。从数字模型中获取牙齿的颊舌向倾斜度和横向测量值，以将它们与骨变化相关联。使用的统计检验包括t检验、方差分析和Pearson相关检验（P<0.05）。

结果

在评估的96个区域中，84个区域显示牙槽骨厚度增加或稳定，12个区域显示明显的骨质流失。骨变化与牙齿倾斜度和横向测量值无关。

结论

在本研究的局限性内，成年患者使用隐适美隐形矫治器进行轻度上颌扩弓不会导致临床上显著的牙槽骨厚度丧失。
