摘要 目的探讨微型种植体支抗在口腔正畸治疗中的应用效果。方法 80例患者均为2013年8月~2015年5月来我院进行口腔正畸治疗的患者,按照支抗方法不同分为两组,每组40例。分别采用Nance弓治疗和微型种植体支抗治疗。观察两组患者的治疗效果,随访半年,分析患者磨牙移位情况、上中切牙倾角差、凸距差变化。同时比较两组患者治疗过程中不良反应发生情况。结果 观察组患者治疗后的总有效率为92.5%,显著高于对照组患者治疗后的总有效率82.5%,差异有统计学意义(P〈0.05)。随访半年,观察组患者磨牙移位情况、上中切牙倾角差、凸距差变化情况均显著优于对照组,差异有统计学意义(P〈0.05)。治疗过程中,观察组患者的不良反应发生率显著低于对照组,差异有统计学意义(P〈0.05)。结论 针对口腔正畸患者可行微型种植体支抗技术,相较于非种植体的支抗技术效果更好,且不会对患者造成较大的影响,安全性更高,值得推广。 Objective To investigate the application effect of micro-implant anchorage in orthodontic treatment.Methods A total of 80 patients who were treated with oral orthodontic treatment in our hospital from August 2013 to May 2015 were divided into two groups according to the different methods of anchorage. Nance bow treatment and microimplant anchorage therapy were performed respectively. The curative effect was observed in the two groups of patients,followed up for six months. The displacement of the molars, the difference of the inclinations between the upper incisor and central incisor, and the changes of the difference of the convex distance were analyzed. At the same time, the incidence of adverse reactions during the course of treatment was compared between the two groups. Results In the observation group, the total effective rate was 92.5%, which was significantly better than that of 82.5% in the control group.The difference was statistically significant(P〈0.05). During the follow-up period of six months, there were significant differences in the displacement of the molars, the difference of the inclinations between the upper incisor and central incisor, and the changes of the difference of the convex distance between the observation group and the control group(P〈0.05). In the course of treatment, the incidence of adverse reactions in the observation group was significantly lower than that in the control group, and the difference was statistically significant(P〈0.05). Conclusion For the patients receiving oral orthodontics, micro-implant anchorage technique is more effective than non-implant anchorage technique. It does not have too much influence on the patients and the safety is high, which is worthy of promotion.
