无托槽隐形矫正推磨牙向后在成人正畸中的应用效果分析

Analysis on Application Effect of Clear Aligner Orthodontic Treatment for Molar Distalization in Adult Orthodontics

目的:分析无托槽隐形矫正推磨牙向后在成人正畸中的应用效果。方法:选取2017年1月—2023年1月陇南市第一人民医院收治的60例口腔正畸患者作为研究对象,按照随机数字表法分为观察组、对照组,各30例。对照组应用固定矫治器治疗,观察组应用无托槽隐形矫正。比较两组正畸效果。结果:治疗后,两组探诊出血指数、牙龈指数、牙齿松动度、探诊深度低于治疗前,且观察组低于对照组,差异有统计学意义(P<0.05)。治疗后,两组咀嚼效率、咬合速率高于治疗前,且观察组高于对照组,差异有统计学意义(P<0.05)。观察组对口腔功能、美观度、舒适度、便捷度的满意度评分高于对照组,差异有统计学意义(P<0.05)。两组并发症发生率比较,差异无统计学意义(P>0.05)。结论:无托槽隐形矫正推磨牙向后在成人正畸中的应用效果显著,可改善患者牙周指数、咀嚼功能,提高患者满意度,且安全性较高。

Objective:To analyze the application effect of clear aligner orthodontic treatment for molar distalization in adult orthodontics.Methods:A total of 60 orthodontic patients admitted to the First People's Hospital of Longnan from January 2017 to January 2023 were selected as the study subjects.They were divided into control group and observation group according to random number table method,with 30 cases in each group.The control group received fixed appliance treatment,while the observation group received clear aligner orthodontic treatment.The orthodontic effects of two groups were compared.Results:After treatment,the bleeding index,gingival index,tooth mobility and probing depth in the two groups were lower than those before treatment,and these indexes in the observation group were lower than those in the control group,and the difference was statistically significant(P<0.05).After treatment,the chewing efficiency and bite rate in the two groups were higher than those before treatment,and these indexes in the observation group were higher than those in the control group,and the difference was statistically significant(P<0.05).The satisfaction scores of oral function,aesthetics,comfort and convenience in the observation group were higher than those in the control group,and the difference was statistically significant(P<0.05).There was no significant difference in the incidence of complications between the two groups(P>0.05).Conclusion:The application effect of clear aligner orthodontic treatment for molar distalization in adult orthodontics is significant,which can improve the periodontal index,masticatory function,and patient's satisfaction,with a high safety.
