摘　　要：目的探讨在口腔正畸治疗中采用微型种植体支抗的有效性及安全性。方法38例接受口腔正畸治疗的患者,按照就诊时间先后顺序分为对照组和研究组,每组19例。对照组采用常规支抗治疗,研究组采用微型种植体支抗治疗。对比两组正畸情况(磨牙移位、上中切牙倾角差、上中切牙凸距差)、咀嚼功能(咀嚼效率及咬合力)、牙龈指标(牙龈指数、出血指数、菌斑指数)、治疗后头影测量结果(MP、SNA、SN、SNB、ANB、Z角)、不良反应发生情况。结果研究组磨牙移位(3.26±0.71)mm、上中切牙倾角差(12.78±6.55)°、上中切牙凸距差(2.49±0.93)mm均小于对照组的(5.59±1.51)mm、(26.60±7.38)°、(3.85±1.34)mm,差异具有统计学意义(P<0.05)。研究组咀嚼效率(0.93±0.16)及咬合力(155.53±23.48)Ibs均大于对照组的(0.74±0.13)、(108.05±25.12)Ibs,差异具有统计学意义(P<0.05)。研究组牙龈指数、出血指数、菌斑指数分别为(1.10±0.36)、(1.09±0.53)、(0.86±0.20),均低于对照组的(1.37±0.29)、(1.41±0.26)、(0.99±0.13),差异具有统计学意义(P<0.05)。治疗后,研究组MP、SNA、SN、SNB、ANB、Z角均优于对照组,差异具有统计学意义(P<0.05)。研究组不良反应发生率5.26%(1/19)低于对照组的36.84%(7/19),差异具有统计学意义(P<0.05)。结论在口腔正畸治疗中,微型种植体支抗的应用可提高正畸效果。Objective To discuss the effectiveness and safety of micro-implant anchorage in orthodontic treatment.Methods A total of 38 patients receiving orthodontic treatment were divided into the control group and the research group according to the order of visiting time,with 19 cases in each group.The control group received conventional anchorage treatment,and the research group received mini-implant anchorage treatment.Both groups were comparer!in terms of orthodontic conditions(molar shift,difference in inclination of upper central incisor,difference in convex distance of upper central incisor),masticatory function(masticalory efficiency and bite force),gingival indicators(gingival index,bleeding index,plaque index),cephalometric measurement results(MP,SNA,SN,SNB,ANB,Z angle),and occurrence of adverse reactions after treatment.Results The molar shift,difference in inclination of upper central incisor,difference in convex distance of upper central incisor of the research group were(3.26±0.71)mm,(12.78±6.55)°,and(2.49±0.93)mm,which were less than(5.59±1.51)mm,(26.60±7.38)°,and(3.85±1.34)mm of the control group,and the difference was statistically significant(P<0.05).The masticatory efficiency(0.93±0.16)and bite force(155.53±23.48)Ihs of the research group were higher than(0.74±0.13)and(108.05±25.12)Ihs of the control group,and the difference was statistically significant(/MIOS).The gingival index,hleeding index,anrl plaque index of the research group were(1.10±0.36),(1.09±0.53),and(0.86±0.20),which were lower than(1.37±0.29),(1.41±0.26),and(0.99±0.13)of the control group,and the difference was statistically significant(P<0.05).After treatment,the MP,SNA,SN,SNB,ANB,and Z angles of the research group were better than those of the control group,and the difference was statistically significant(P<0.05).The incidence of adverse reactions 5.26%(1/19)in the research group was lower than 36.84%(7/19)in the control group,and the difference was statistically significant(P<0.05).Conclusion In orthodontic treatment
