无托槽隐形矫治器与自锁托槽对成人正畸效果及生活质量影响的比较

Bracketless invisible appliance versus self-ligating bracket for orthodontic effect and quality of life in adults

目的比较无托槽隐形矫治器与自锁托槽对成人正畸患者咬合功能、牙周健康及生活质量的影响。方法100例成年错颌畸形患者随机接受无托槽隐形矫治器(治疗组)和自锁托槽矫治(对照组)治疗,对两组患者矫治后24 h咬合功能、6个月牙周健康和生活质量进行比较。结果矫治后24 h,治疗组咀嚼次数、咀嚼效能、最大咬合力、最大合力时间及咬合速率均显著高于对照组(P<0.01)。矫治后6个月,治疗组牙龈指数、龈沟探诊深度、龈沟出血指数及菌斑指数等均显著低于对照组(P<0.01或0.05),而生活质量指标优于对照组(P<0.01)。结论无托槽隐形矫治器可降低成年错颌畸形患者咬合功能障碍、维护牙周健康、提高生活质量。

Objective To compare the effect of non-bracket invisible appliance(NBIA)versus self-ligating bracket(SLB)on occlusal function,periodontal health,and quality of life(QOL)in adult orthodontic patients.Methods One hundred adult patients with malocclusion were randomly treated with NBIA(treatment group)or SLB(control group).The 24-h occlusal function and 6-month periodontal health and QOL were compared between 2 groups.Results After 24 hours of correction,chewing times/efficiency,maximal bite force and its time,and bite rate were higher in treatment group than in control group(P<0.01).After 6 months of treatment,gingival index,sulcus probing depth,sulcular bleeding index and plaque index were significantly lower(P<0.01 or 0.05)but QOL was better(P<0.01)in treatment group compared with control group.Conclusion NBIA can reduce occlusion dysfunction,maintain periodontal health,and improve QOL in adult patients with malocclusion.
