Abstract

Objective: This study compared dentoskeletal and soft tissue changes with face mask (FM) therapy. Rapid maxillary expansion (RME) and alternate rapid maxillary expansion and constriction (Alt-RAMEC) protocols were used with the two different types of expansion appliance, and their effects on the treatment outcome were investigated.

Methods: The study consisted of 79 (37 and 42 patients in the RME and Alt-RAMEC groups with FM, respectively) patients who had received FM treatment. The effects of the RME/FM (20 female, 17 male) and Alt-RAMEC/FM (14 female, 28 male) protocols were evaluated using lateral cephalometric films. The chronological ages of the RME/FM and Alt-RAMEC/FM groups were 11.58 and 11.99 years, respectively. In addition, both groups were divided into two subgroups based on the design of the expansion appliance (Spolyar or full coverage type). Differences in all parameters were analyzed using Student's t-tests.

Results: The maxilla significantly moved forward in both the RME/FM and Alt-RAMEC/FM groups (p<0.001). No significant skeletal differences were observed between the groups. Sagittal movement of the upper incisors significantly increased, and the lower incisors significantly retruded in both groups. While similar skeletal changes were found between the Spolyar and full-coverage appliance groups, the upper incisors protruded significantly more in the full-coverage type.

Conclusion: RME/FM and Alt-RAMEC/FM therapies were found to be efficient for maxillary protraction and resulted in similar skeletal changes. A full-coverage expansion appliance produced a more upper incisor protrusion than a spherical-type appliance.

快速上颌扩张和快速上颌扩张与收缩交替方案与面罩疗法的比较。
研究目的本研究比较了面罩(FM)疗法对牙科骨骼和软组织的影响。研究采用了快速上颌扩张(RME)和交替快速上颌扩张和收缩(Alt-RAMEC)两种不同类型的扩张器,并调查了它们对治疗效果的影响:研究对象包括79名接受过调频治疗的患者(RME组和Alt-RAMEC组分别有37名和42名调频患者)。使用头颅侧位片对 RME/FM(20 名女性,17 名男性)和 Alt-RAMEC/FM(14 名女性,28 名男性)方案的效果进行了评估。RME/FM 组和 Alt-RAMEC/FM 组的实际年龄分别为 11.58 岁和 11.99 岁。此外,根据扩弓器的设计(Spolyar 型或全覆盖型),两组又分为两个亚组。所有参数的差异均采用学生 t 检验进行分析:结果:RME/FM组和Alt-RAMEC/FM组的上颌骨均明显前移(p研究发现,RME/FM和Alt-RAMEC/FM疗法对上颌骨前移很有效,并能带来相似的骨骼变化。与球形矫治器相比,全覆盖扩张矫治器产生的上切牙前突更多。
