摘要 目的探讨微型种植体支抗应用于口腔正畸治疗的临床效果。方法选择在临沂市经济技术开发区人民医院行正畸治疗的100例患者为研究对象,随机分为对照组和观察组各50例。对照组患者采用非微型种植体支抗(口外弓支抗)治疗,观察组植入微型钛钉种植体治疗,观察两组患者治疗9个月后,磨牙移位、上中切牙倾角差、上中切牙凸距差、术后并发症发生率等情况。结果观察组磨牙移位显著小于对照组,上中切牙倾角差、上中切牙凸距差均显著大于对照组,组间差异均有统计学意义(P〈0.05);观察组术后并发症发生率显著低于对照组,差异有统计学意义(P〈0.05)。结论微型种植体支抗用于口腔正畸治疗矫治效果较好,磨牙前移、上中切牙外凸改善良好,且并发症风险较低、舒适度高,临床疗效可靠。 Objective To explore the clinical effect of micro-implant anchorage on orthodontic treatment.Methods 100 patients undergoing orthodontic treatment in our hospital were chosen and randomly divided into the control group and the observation group,with 50 patients in each group.The patients in the control group were treated with extraoral anchorage and the patients in the observation group were treated with micro-implant anchorage.After nine months of treatment,the molar displacement,upper central incisor angle difference,upper central incisor convexity gap and postoperative complications were compared between the two groups.Results The molar displacement in the observation group was significantly less than that in the control group,and the upper central incisor angle difference and upper central incisor convexity gap in the observation group was much more than those in the control group(P〈 0.05).The rate of postoperative complication in the observation group was significantly lower than that in the control group(P 〈0.05).Conclusion Micro-implant anchorage is highly effective in orthodontic treatment,and can improve the condition of molar anterior displacement and upper central incisor protrusion with high comfort level and reliable clinical effect.
