摘　　要：目的探讨采用自攻型微种植体支抗钉完成正畸治疗后对患者临床稳定性的影响。方法选取2018年1月1日—2020年12月31日收治的58例成年双颌前突畸形患者进行正畸治疗,随机分为助攻型组(助攻型支抗种植体)和自攻型组(自攻型微种植体支抗钉),每组各29例;比较两组患者支抗成功率、支抗体脱落率以及自攻型组X线投影测量值变化情况。结果针对患者在实施正畸治疗过程中,微种植体均耐受良好,附近软组织未表现出感染炎症以及显著水肿症状。完成治疗后,患者牙齿排列整齐,面型良好。自攻型组29例患者中,支抗体上颌脱落患者2例,下颌脱落患者1例,总脱落3例(10.34%),成功26例(89.66%);助攻型组29例患者中,支抗体上颌脱落患者3例,下颌脱落患者1例,总脱落4例(13.79%),成功25例(86.21%);自攻型组支抗成功率、支抗体脱落率同助攻型组比较,差异无统计学意义(P>0.05);治疗前,U1-L1为(103.49±9.49)°、U1-SN为(112.19±7.36)°、UL-E Plane为(3.63±1.55)mm、U6-Y为(38.49±3.63)mm、U1-Y为(72.93±8.36)mm、LL-E Plane为(6.03±1.66)mm、前牙覆盖为(9.83±1.52)mm;治疗后,U1-L1为(121.59±3.39)°、U1-SN为(102.25±4.59)°、UL-E Plane为(1.16±0.12)mm、U6-Y为(38.85±3.35)mm、U1-Y为(65.72±8.46)mm、LL-E Plane为(1.93±0.77)mm、前牙覆盖为(1.90±0.14)mm;除U6-Y在治疗前后未呈现出明显差异,其余差异均有统计学意义(P<0.05)。结论自攻型微种植体支抗钉不需要进行种植孔预备,对患者不会造成严重骨损伤,操作简单,可将上颌前牙有效内收,对上颌前突进行有效治疗,对支抗磨牙的稳定性做出保证,呈现应用前景良好的特点。Objective To investigate the effect of self-tapping micro-implant anchorage nails on clinical stability after orthodontic treatment.Methods A total of 58 adult patients with bimaxillary protrusion deformity were selected from January 1,2018 to December 31,2020 for the study of orthodontic treatment.They were randomly divided into two groups:attack group(attack type anchorage implant)and self-attack group(attack type micro-implant anchorage nail),with 29 cases in each group.The success rate of anchorage and the shedding rate of branched antibodies were compared between the two groups,as well as the changes of X-ray projection measurements in the selfattacking group.Results In the course of orthodontic treatment,the microimplants were well tolerated,and no infection and inflammation or significant edema were shown in the nearby soft twassues.After the treatment,the patient's teeth were arranged neatly and the facial shape was good.Among the 29 patients in the self-attack group,there were 2 cases of maxillary abscwassion with branched-antibody,1 case of mandible abscwassion,and 3 cases of total abscwassion(10.34%).26 cases(89.66%)were successful.In the auxiliary group of 29 patients,there were 3 cases of maxillary abscwassion of branched-antibody,1 case of mandible abscwassion,and 4 cases of total abscwassion(13.79%).25 cases(86.21%)were successful.There were no significant differences in the success rate of anchorage and the abscwassion rate of anchorage antibodies between the self-attack group and the supporting group(P>0.05).Before the treatment,U1-L1 was(103.49±9.49)°,U1-SN was(112.19±7.36)°,Ul-E Plane was(3.63±1.55)mm,U6-Y was(38.49±3.63)mm,U1-Y was(72.93±8.36)mm,and LL-E Plane was(6.03±1.66)mm,anterior tooth coverage was(9.83±1.52)mm;After treatment,U1-L1 was(121.59±3.39)°,U1-SN was(102.25±4.59)°,UL-E Plane was(1.16±0.12)mm,U6-Y was(38.85±3.35)mm,U1-Y was(65.72±8.46)mm,and LL-E Plane was(1.93±0.77)mm,anterior tooth coverage was(1.90±0.14)mm;Except for U6-Y,which showed no significant differen
