摘　　要：目的:对比分析滑动与传动直丝弓技术治疗成人双颌前突的疗效。方法:选择2017年6月~2019年6月我院收治的成人双颌前突患者88例,按照随机数字表法分为2组,每组各44例。对照组行滑动直丝弓配合种植钉支抗或口外弓矫治,观察组行传动直丝弓技术矫治。对比两组治疗时间、治疗前后硬、软组织指标变化情况。结果:观察组治疗时间短于对照组,差异有统计学意义(P<0.05)。观察组治疗后SNA角、SNB角、ANB角与对照组相比,差异均无统计学意义(P>0.05);观察组治疗后MP/SN低于对照组,两组治疗后U1/SN、U1/NA、U1-NA、L1/NB、L1-NB、U1-AP、L1-AP、LL-EP、UL-EP低于治疗前,差均有统计学意义(P<0.05),治疗后组间比较差异无统计学意义(P>0.05)。两组治疗后U1/L1、Z角、鼻唇角高于治疗前,差异均有统计学意义(P<0.05),治疗后组间比较差异无统计学意义(P>0.05)。结论:对双颌前突患者采用传动直丝弓技术及滑动直丝弓技术治疗均可取得满意效果,传动直丝弓技术可较早改善患者侧面容貌,但上前牙存在过于直立现象,临床应注意上前牙的转矩控制。Objective:To compare the effects of sliding and transmission straight wire arch technique in the treatment of adult bilateral maxillary protrusion.Methods:Eighty-eight adult patients with bilateral maxillary protrusions were enrolled in our hospital from June 2017 to June 2019.They were divided into two groups according to the random number table method,44 cases each.The control group was treated with sliding straight wire arch and implanted nail anchorage or extraoral arch treatment.The observation group was treated with straight wire arch technique.The changes of the hard and soft tissue indexes before and after treatment were compared between the two groups.Results:The treatment time of the observation group was shorter than that of the control group,and the difference was statistically significant(P<0.05).There was no significant difference in the SNA angle,SNB angle and ANB angle between the observation group and the control group respectively(P>0.05).The MP/SN of the observation group was lower than that of the control group after treatment.After treatment,U1/SN,U1/NA,U1-NA,L1/NB,L1-NB,U1-AP,L1-AP,LL-EP,UL-Before EP was lower than the treatment,the difference was statistically significant respectively(P<0.05).There was no significant difference between the two groups after treatment(P>0.05).After treatment,the U1/L1,Z angle and nasolabial angle were higher than those before treatment,the difference was statistically significant respectively(P<0.05),and there was no significant difference between the groups after treatment(P>0.05).Conclusion:The patients with bimaxillary protrusions can achieve satisfactory results by adopting the technique of transmission straight wire arch and sliding straight wire arch.The technique of straight wire arch can improve the lateral appearance of patients,but the upper anterior teeth are too erect.Clinical attention should be paid to the torque control of the upper anterior teeth.
