Abstract：
UNASSIGNED: The present study investigated the skeletal and dental effect in class II division I growing patients due to mandibular deficiency treated with the hybrid aesthetic functional (HAF) appliance.
UNASSIGNED: A sample of 16 growing patients (5 boys and 11 girls; mean age: 9.50 years, standard deviation: 1.15) with class II division I malocclusion were treated using the HAF appliance for an average period of 10±3 months. For each patient, a cephalometric radiograph was taken before and after treatment, and digital analysis was applied using the WebCeph program. The statistical analysis was performed to evaluate dental and skeletal changes associated with the HAF appliance and determine if there were any statistically significant variations in anatomical measurements between the start and completion of the treatment.
UNASSIGNED: The data showed a significant increase in SNB angle (P=0.002), leading to a significant decrease in ANB angle (P=0.001). The mandibular length significantly increased (P=0.008), the lower incisors were flared significantly (P=0.028), and the lower molars were extruded significantly (P≤0.001). Also, this study revealed a significant decrease in Wits appraisal (P≤0.001), overjet (P≤0.001), and overbite (P=0.041). Additionally, a significant increase in lower anterior facial height (P≤0.001), total facial height (P=0.001), and posterior facial height (P=0.037) were observed.
UNASSIGNED: The HAF appliance showed that it could be used to correct class II division 1 skeletal discrepancy by mandibular advancement. The HAF appliance increased all facial heights significantly.

摘要：
■本研究调查了由于使用混合美学功能（HAF）矫治器治疗的下颌骨缺乏而导致的II类I级成长患者的骨骼和牙齿效应。
■16名成长患者的样本（5名男孩和11名女孩；平均年龄：9.50岁，标准偏差：1.15）使用HAF矫治器治疗II类I类咬合不正，平均时间为10±3个月。对于每个病人来说,在治疗前后拍摄头颅X光片，并使用WebCeph程序进行了数字分析。进行统计分析以评估与HAF矫正器相关的牙齿和骨骼变化,并确定在治疗开始和完成之间在解剖学测量中是否存在任何统计学上显著的变化。
■数据显示SNB角度显着增加（P=0.002），导致ANB角显著减小（P=0.001）。下颌长度显著增加(P=0.008),下切牙显著扩张(P=0.028),下磨牙明显挤压(P≤0.001)。此外，这项研究显示，机智评价显著下降(P≤0.001)，喷射机(P≤0.001)，和过咬合（P=0.041）。此外,下前面部高度显着增加（P≤0.001），面部总高度（P=0.001），观察到面部后部高度（P=0.037）。
■HAF矫治器表明，它可用于通过下颌前移来纠正II类1级骨骼差异。HAF器具显著增加了所有面部高度。
