无托槽隐形矫治在口腔正畸患者中的疗效研究

Study on efficacy of bracketless invasible appliance on orthodontic patients

目的分析无托槽隐形矫治在口腔正畸患者中的临床效果。方法94例口腔正畸患者,按随机数字表法分为对照组和研究组,各47例。对照组患者采用固定矫治治疗,研究组患者采用无托槽隐形矫治治疗。比较两组患者治疗前后牙龈指数、视觉模拟评分法(VAS)评分及并发症发生情况、矫治满意度。结果治疗后,研究组牙龈指数(0.93±0.16)分低于对照组的(1.52±0.14)分,差异具有统计学意义(P<0.05)。治疗后,研究组VAS评分(1.74±0.43)分明显低于对照组的(4.61±1.32)分,差异具有统计学意义(P<0.05)。研究组并发症发生率为2.13%,低于对照组的27.66%,差异具有统计学意义(P<0.05)。研究组咀嚼功能、语言功能、舒适度、美观性评分分别为(8.41±1.12)、(7.62±1.54)、(7.32±1.24)、(8.23±1.06)分,均高于对照组的(6.52±1.19)、(5.23±1.36)、(4.27±1.29)、(5.26±1.57)分,差异具有统计学意义(P<0.05);两组固位性评分比较差异无统计学意义(P>0.05)。结论无托槽隐形矫治在口腔正畸患者中的疗效显著,可降低疼痛程度,维持牙龈健康,减少并发症,提高矫治满意度,临床上值得推广使用。

Objective To analyze the clinical effect of bracketless invisible appliance on orthodontic patients.Methods A total of 94 orthodontic patients were divided into control group and study group according to the random numerical table,with 47 cases in each group.The control group was treated with fixed orthodontics,and the study group was treated with bracketless invisible appliance.The gingival index and visual analogue scale(VAS)score before and after treatment,complication occurrence and satisfaction with orthodontic treatment were compared between the two groups.Results After treatment,the gingival index of(0.93±0.16)points in the study group was lower than that of(1.52±0.14)points in the control group,and the difference was statistically significant(P<0.05).After treatment,VAS score of(1.74±0.43)points in the study group was significantly lower than that of(4.61±1.32)points in the control group,and the difference was statistically significant(P<0.05).The incidence of complications in the study group was 2.13%,which was lower than that of 27.66%in the control group,and the difference was statistically significant(P<0.05).The scores of chewing function,language function,comfort and aesthetics in the study group were(8.41±1.12),(7.62±1.54),(7.32±1.24)and(8.23±1.06)points,which were higher than those of(6.52±1.19),(5.23±1.36),(4.27±1.29)and(5.26±1.57)points in the control group,and the differences were statistically significant(P<0.05).There was no statistically significant difference in retention scores between the two groups(P>0.05).Conclusion Bracketless invisible appliance has significant curative effect on orthodontic patients,which can reduce pain level,maintain gum health,reduce complications and improve satisfaction with orthodontic treatment.It is worth promoting in clinical practice.
