摘　　要：目的:观察微型种植体支抗在错牙合畸形口腔正畸治疗患者中的应用效果。方法:选取2020年7月至2022年7月该院收治的84例错牙合畸形口腔正畸治疗患者进行前瞻性研究,按随机数字表法将其分为对照组与观察组各42例。对照组给予传统支抗治疗,观察组给予微型种植体支抗治疗。比较两组牙齿结构相关指标水平、舒适度评分、临床疗效和不良事件发生率。结果:观察组磨牙位移小于对照组,上中切牙凸距差、上中切牙倾角差均大于对照组,差异有统计学意义(P<0.05);观察组舒适度评分高于对照组,差异有统计学意义(P<0.05);观察组治疗总有效率为95.24%(40/42),高于对照组的76.19%(32/42),差异有统计学意义(P<0.05);两组不良事件发生率比较,差异无统计学意义(P>0.05)。结论:微型种植体支抗应用于错牙合畸形口腔正畸治疗患者可提高治疗总有效率和舒适度评分,改善牙齿结构相关指标水平,其效果优于传统支抗治疗。Objective:To observe application effects of micro-implant anchorage in orthodontic treatment of patients with malocclusion deformities.Methods:A prospective study was conducted on 84 patients with malocclusion deformities undergoing orthodontic treatment admitted to the hospital from July 2020 to July 2022.According to the random number table method,they were divided into control group and observation group,42 cases in each group.The control group was given traditional anchorage treatment,while the observation group was given the micro-implant anchorage treatment.The level of tooth structure related indicators,the comfort score,the clinical efficacy,and the incidence of adverse events were compared.Results:The of molar displacement in the observation group was smaller than that in the control group,the upper central incisor convex distance difference and the upper central incisor inclination difference were larger than those in the control group,and the differences were statistically significant(P<0.05).The comfort score of the observation group was higher than that of the control group,and the difference was statistically significant(P<0.05).The total effective rate of treatment in the observation group was 95.24%(40/42),which was higher than 76.19%(32/42)in the control group,and the difference was statistically significant(P<0.05).However,there was no significant difference in the incidence of adverse events between the two groups(P>0.05).Conclusions:The application of micro-implant anchorage in the orthodontic treatment of the patients with malocclusion deformities can improve the total effective rate and the comfort scores and improve the levels of tooth structure related indicators.Moreover,it is superior to the traditional anchorage therapy.
