摘要
目的探讨FRⅢ功能矫治对功能性伴早期骨性安氏Ⅲ类错患者上气道间隙的影响。方法分别选取功能性伴早期骨性安氏Ⅲ类错患者23例为治疗组,平均9.8岁;正常23例对照组,平均10岁;两组均为男10例,女13例。治疗组采用FRⅢ功能矫治,对照组采用观察,平均时间为10个月。分别拍摄实验前后X线头影测量片进行测量及统计学处理。结果和正常组相比FRⅢ功能矫治后软腭尖后气道间隙显著变小(P≤0.05),其余均无显著性差异。结论FRⅢ功能矫治对上气道软腭尖后气道间隙有影响,其余上气道间隙未见明显改变。
Objective To evaluate the effects on the upper airway afte treatment of Angle ClassⅢ malocclusion by FRⅢ appliance.Methods Forty-six children were collected, 23 of them (male 10,femal 13) were normal occlusion and 23 (10 male,femal 13) were functional or early skeletal Angle Class Ⅲ malocclusion. The normal occlusion group was observed for 10 months, the patient group was treated by FRⅢ for 10 months. Cephalometric data were collected at the start and the end of the study. Statistical analysis were applied.Results Compared with the normal group , U-MP of the post-treatment of Angle Class Ⅲ malocclusion was smaller (P≤0.05).Conclusion U-MP of the patients was changed by FRⅢ treatment and there was no other signifficient change in the airway.
