摘　　要：目的分析微型种植体支抗钉结合滑动法与关闭曲法治疗安氏Ⅱ类1分类错[牙合]畸形的效果。方法选取2020年1月至12月我院收治的80例安氏Ⅱ类1分类错[牙合]畸形患者为研究对象,按照随机法将其分为关闭曲组(微型种植体支抗钉结合关闭曲法治疗)和滑动组(微型种植体支抗钉结合滑动法治疗),每组40例。比较两组的治疗效果。结果治疗后,滑动组的ANB角、Wits值、FMA角、IMPA角小于关闭曲组,Z角、FMIA角大于关闭曲组(P<0.05)。治疗后,滑动组的牙龈指数(GI)、龈沟出血指数(SBI)、菌斑指数(PLI)评分及牙周探诊深度(PD)、附着丧失(AL)低于关闭曲组(P<0.05)。滑动组的不良事件总发生率低于关闭曲组(P<0.05);两组的前后牙消耗支抗比较,差异无统计学意义(P>0.05)。结论相较于微型种植体支抗钉结合关闭曲法,微型种植体支抗钉结合滑动法治疗安氏Ⅱ类1分类错[牙合]畸形可改善错[牙合]畸形与牙周指标,取得显著的正畸治疗效果,且不良事件发生率低。Objective To analyze the effects of micro-implant anchorage nail combined with sliding method and closing curve method in the treatment of Angle's classⅡdivision 1 malocclusion.Methods A total of 80 patients with Angle's classⅡdivision 1 malocclusion admitted in our hospital from January to December 2020 were selected as the research objects.According to the random method,the patients were divided into closing curve group(micro-implant anchorage nail combined with closing curve method)and sliding group(micro-implant anchorage nail combined with sliding method),with 40 cases in each group.The therapeutic effects of the two groups were compared.Results After treatment,the ANB angle,Wits value,FMA angle and IMPA angle of the sliding group were smaller than those of the closing curve group,and the Z angle and FMIA angle were larger than those of the closing curve group(P<0.05).After treatment,the gingival index(GI),sulcus bleeding index(SBI),plaque index(PLI)scores,probing depth(PD)and attachment loss(AL)in the sliding group were lower than those in the closing curve group(P<0.05).The total incidence of adverse events in the sliding group was lower than that in the closing curve group(P<0.05);there was no significant difference in anterior and posterior tooth consumption anchorage between the two groups(P>0.05).Conclusion Compared with the micro-implant anchorage nail combined with closing curve method,the micro-implant anchorage nail combined with sliding method in the treatment of Angle's class Ⅱ division 1 malocclusion can improve the malocclusion and periodontal indexes,achieve significant orthodontic treatment effect,and has low incidence of adverse events.
