摘要
目的:评估隐适美通过扩弓方法治疗轻中度牙列拥挤患者的临床效果。方法:通过选取12例牙列拥挤度≤6mm隐适美非拔牙成人患者,利用CBCT测量治疗前后上颌牙弓宽度,利用配对t检验分析隐适美的扩弓效果。结果:不同预置扩弓量及不同牙位的扩弓量和扩弓效率均呈现出显著性(P<0.05);T0≥2mm组扩弓量的均值大于T0<2mm组。结论:不同的预置扩弓量和不同牙位均会对扩弓量及扩弓效率产生显著影响。
Objective:Evaluating the clinical effects of clear aligners,in the treatment of mild dental crowding.Methods:12 adults of invisalign with dental crowding≤6mm were selected for non-tooth extraction treatment,their CBCTs were used to measure the maxillary arch width before and after treatment.Paired sample t-test was used to analyze the expansion effect of clear aligners.Results:There were significant differences between different preset and different dental positions(P<0.05).The expansion efficiency of T0≥2 mm group is larger than the T0<2 mm group.Conclusion:Different presets and dental positions have significant influence on the expansion efficiency.
