This study aimed to assess skeletal and upper airway modifications induced by the Twin Block appliance in patients with Class II malocclusion due to mandibular retrusion, using two-dimensional imaging techniques. A total of 11 patients (6 males, 5 females) were included and stratified into two groups (Pre-Peak and Peak) based on skeletal maturity evaluated through the cervical vertebral maturation (CVM) method. Lateral cephalometric radiographs were obtained at the beginning (T0) and end (T1) of treatment and analyzed using DeltaDent software. The appliance was worn full-time, except during meals and oral hygiene procedures, with monthly follow-ups. Significant changes were observed between T0 and T1 across the sample. Comparison between groups revealed statistically significant differences only in the H-C3a1 and vertical height (th) parameters ( < 0.05). In conclusion, the Twin Block appliance proved effective in enhancing mandibular and dental positioning, while also exerting a favorable influence on upper airway development.
本研究旨在采用二维成像技术，评估 Twin Block 矫治器对下颌后缩所致安氏 II 类错牙合患者骨骼及上气道的改变。共纳入 11 例患者（6 例男性，5 例女性），并根据通过颈椎成熟度（CVM）方法评估的骨骼成熟度分为两组（高峰前期和高峰期）。在治疗开始（T0）和结束（T1）时获取头颅侧位 X 线片，并使用 DeltaDent 软件进行分析。矫治器除用餐和口腔卫生清洁时外需全天佩戴，每月进行随访复查。整个样本在 T0 和 T1 之间观察到显著变化。组间比较仅在 H-C3a1 和垂直高度（th）参数上显示出统计学显著差异（<0.05）。总之，Twin Block 矫治器被证明在改善下颌及牙齿位置方面有效，同时对上气道发育也有积极影响。
