摘　　要：目的 研究微型种植体支抗控制技术在替牙期儿童口腔正畸矫正治疗中的应用效果。方法 回顾性以2020年1月至2022年1月广州市妇女儿童医疗中心收治入院进行口腔正畸治疗的50例替牙期儿童为观察对象,参考支抗控制方式分为研究组(n=25)与对照组(n=25)。研究组选取微型种植体对磨牙予以支抗控制,对照组选取口外弓对磨牙予以支抗控制。比较两组患儿治疗前后头影测量数据指标(Z角、SNB角、ANB角、SNA角、SN角、MP角、U1/L1、OB、OJ)与治疗后上中切牙倾角差、上中切牙凸距差、磨牙移位、咬合力、咀嚼效率、总有效率及不良反应(软组织水肿、口腔感染、口腔不适)发生率。结果 治疗前,两组患儿头影测量数据指标比较,差异均无统计学意义(P>0.05);较治疗前,两组患儿治疗后Z角、SNB角、ANB角、SNA角、SN角、MP角、U1/L1、OB、OJ更低,差异均有统计学意义(P<0.05);治疗后,研究组患儿较对照组Z角、SNB角、U1/L1更高,ANB角、SNA角、SN角、MP角、OB、OJ更低,差异均有统计学意义(P<0.05)。治疗后,研究组患儿上中切牙倾角差、上中切牙凸距差、磨牙移位距离分别为(13.31±6.83)°、(2.51±0.72)°、(3.92±0.27)mm,均显著低于对照组[(29.57±9.38)°、(4.63±1.42)°、(6.32±0.63)mm],差异均有统计学意义(P<0.05)。研究组患儿治疗后咬合力、咀嚼效率、总有效率分别为(129.28±35.17)N、0.67±0.31、96.00%,均显著高于对照组[(96.39±30.85)N、0.49±0.28、68.00%],不良反应发生率为4.00%,低于对照组(32.00%),差异均有统计学意义(P<0.05)。结论 微型种植体支抗控制技术用于替牙期儿童口腔正畸矫正治疗中的效果显著,可显著改善患儿牙齿畸形,还可提升定向力控制效果、咀嚼效率及咬合力,且不良反应少。Objective To study the effect of micro-implant anchorage control technology in orthodontic treatment of children during tooth replacement period.Methods Retrospective analysis was used to study 50 children who were hospitalized in Guangzhou Women and Children’s Medical Center for orthodontic treatment from January 2020 to January 2022, and they were divided into study group(n=25) and control group(n=25) according to anchorage control method. In the study group, micro implants were used to control molar anchorage, while in the control group, external arch was used to control molar anchorage. The head shadow measurement data index(Z angle, SNB angle, ANB angle, SNA angle, SN angle, MP angle, U1/L1, OB, OJ) with high incisor inclination difference after treatment, high cutting teeth protruding distance difference, molar shift, chomp, chew efficiency, total effective rate, adverse reactions(soft tissue edema, oral infection, oral discomfort) rates were compared beteween the two groups before and after the treatment.Results Before treatment, there was no significant difference in cephalometric data between the two groups(P>0.05);compared with before treatment, Z angle, SNB angle, ANB angle, SNA angle, SN angle, MP angle, U1/L1, OB, OJ were lower in two groups after treatment, and the differences were significant(P<0.05);after treatment, the Z angle, SNB angle, and U1/L1 of the children in the study group were higher than those in the control group, and the ANB angle, SNA angle, SN angle, MP angle, OB, and OJ were lower than those in the control group, and the differences were statistically significant(P<0.05). After treatment, upper middle incisor inclination difference, upper middle incisor protruding distance, molar displacement distance in the study group were(13.31±6.83)°,(2.51±0.72)°,(3.92±0.27) mm, which were significantly lower than those in the control group[(29.57±9.38)°,(4.63±1.42)°,(6.32±0.63) mm], and the differences were statistically significant(P<0.05). After treatment, the bite force, masti
