目的:观察自锁托槽矫治技术与微种植体支抗联合应用于安氏Ⅱ1s类错牙合矫治的临床效果. 方法:18例安氏Ⅱ1s错牙合患者,男性7例,女性11例,平均年龄25.6岁,均采用上颌拔除两个第一前磨牙,下颌拔除一个第一前磨牙的拔牙模式,使用自锁托槽矫治器联合微种植体支抗矫治.治疗前后拍摄X线头颅定位侧位片,使用配对t检验比较治疗前后头影测量指标的变化.结果:矫治结束后,与矫治前比较,差异有统计学意义(P<0.05).结论:自锁托槽矫治联合微种植体支抗矫治能够明显改善上前牙唇倾度,改善Ⅱ类面型,使软组织侧貌趋于直面型.

Objective:To investigate the clincial effects of Self-ligating technique and microscrew anchorage on Angle Class II division 1 subdivision malocclusion. Method:Choose 18 patients with Angle ClassⅡ division 1 subdivision maloc-clusion (male 7,female 11,average age 25.6),the maxillary premolors of two sides were pulled out,the mandibular pre-molors of one side were pulled out, using Self-ligating technique,the microscrew anchorage was used in maxillary. Result:The angle of SNA、ANB、U1-SN and the distance of U1-NA、LS-E、LI-E decreased,the angle of CmSnLs increased,there was statistically significant difference (P<0.05). Conclusion:Self-ligating technique and microscrew can improve the libial inclination obviously. Angle class II profile was improved.Soft tissue profile tends to be straight-styled.
