Abstract:
60 cases(aged 18-40 years) underwent orthodontic treatment were divided into 2 groups.30 patients in group A were treated with invisible aligners,while 30 in group B with fixed orthodontic appliance.Periodontal indices (PI,GI,SBI,PD)were examined before treatment,6 weekes,6 months and 12 months after treatment.Before and 6 weeks after treatment the indices were not statistically different between groups,6 and 12 months after treatment the indices of group A were lower than those of group B (P ＜ 0.05).The invisalign appliance is more propitious to periodontal health than the fixed orthodontic appliance.
