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 t-test, analysis of variance, and Pearson's correlation tests (p < 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.

成人牙槽骨扩张后清晰对准器对上颌牙槽骨的评价:锥束计算机断层扫描研究。
目的:应用锥形束计算机断层技术,探讨上颌正畸扩展对矫治器治疗的成人患者牙槽骨组织的影响。方法:30例患者,其中女性22例,男性8例;平均年龄:36.3岁),接受Invisalign®矫正器治疗。上弓扩张前(T0)和后(T1)分别获得锥束计算机断层扫描和数字模型。对切牙、犬齿、前磨牙、第一磨牙的颈、中、尖区骨厚度进行颊部和腭部测量,共96个区域,2880个测量值。从数字模型中获得牙齿的颊舌倾斜度和横向测量值,以将它们与骨骼变化相关联。统计学检验采用学生t检验、方差分析和Pearson相关检验(p < 0.05)。结果:在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:在本研究的限制范围内,成人患者使用Invisalign®矫正器获得的轻度上弓扩张不会导致任何临床意义上的牙槽骨厚度损失。

期刊介绍: The Korean Journal of Orthodontics (KJO) is an international, open access, peer reviewed journal published in January, March, May, July, September, and November each year. It was first launched in 1970 and, as the official scientific publication of Korean Association of Orthodontists, KJO aims to publish high quality clinical and scientific original research papers in all areas related to orthodontics and dentofacial orthopedics. Specifically, its interest focuses on evidence-based investigations of contemporary diagnostic procedures and treatment techniques, expanding to significant clinical reports of diverse treatment approaches. The scope of KJO covers all areas of orthodontics and dentofacial orthopedics including successful diagnostic procedures and treatment planning, growth and development of the face and its clinical implications, appliance designs, biomechanics, TMJ disorders and adult treatment. Specifically, its latest interest focuses on skeletal anchorage devices, orthodontic appliance and biomaterials, 3 dimensional imaging techniques utilized for dentofacial diagnosis and treatment planning, and orthognathic surgery to correct skeletal disharmony in association of orthodontic treatment.
