摘　　要：目的:比较微种植体支抗与J钩支抗在双颌前突患者系统矫治中的效果。方法:选取笔者医院2019年5月-2021年5月收治的80例双颌前突患者为研究对象,按随机数字法分为研究组(40例,采用微种植体支抗治疗)和对照组(40例,采用J钩支抗治疗)。记录两组临床疗效、治疗时间、头影测量值相关指标及并发症发生率。结果:治疗后,研究组有效率高于对照组,治疗时间短于对照组,研究组面凸角(G-Sn-Pg’)、鼻唇角(Cm-Sn-UL)大于对照组,下唇-E线间距(Li-E)、上中切牙长轴和NA连线交角(U1-NA)、上中切牙长轴和前颅底平面交角(U1-SN)、下中切牙-下颌平面角(IMPA)、下中切牙长轴和NA连线交角(L1-NB)低于对照组(均P<0.05)。两组并发症发生率比较,差异无统计学意义(P>0.05)。结论:在双颌前突患者系统矫治中,微种植体支抗相较J钩支抗可提高疗效,缩短治疗时间,改善面部状况,安全可靠。Objective To compare the efficacy of micro-implant anchorage and J hook anchorage in the systemic correction of bimaxillary protrusion.Methods Eighty patients with bimaxillary protrusion admitted to our hospital from May 2019 to May 2021 were selected and divided into a study group(40 cases)and a control group(40 cases).The control group was treated with J hook anchorage,and the study group was treated with micro-implant anchorage.Record the clinical efficacy,treatment time,cephalometric measurements and the incidence of complications of the two groups.Results After treatment,the effective rate of the study group was higher than that of the control group,and the treatment time was shorter than that of the control group.The face convex angle(G-Sn-Pg')and nasolabial angle(Cm-Sn-UL)of the study group were larger than those of the control group.The distance between the lower lip E lines(Li-E),the intersection angle between the long axis of the upper central incisor and the NA line(U1-NA),the intersection angle between the long axis of the upper central incisor and the anterior skull base plane(U1-SN),the angle between the lower central incisor and the mandibular plane(IMPA),the intersection angle between the long axis of the lower central incisor and the NA line(L1-NB)were lower than those of the control group(all P<0.05).There was no significant difference in complication rate between the two groups(P>0.05).Conclusion Compared with J-hook anchorage,micro-implant anchorage can improve the therapeutic effect,shorten the treatment time and improve the facial condition in the systematic correction treatment of patients with bimaxillary protrusion,which is safe and reliable.
