简要总结
Fixed Functional Appliances comparisons in treatment of orthodontic class II malocclusion cases
详细描述
Comparison between two types of fixed functional appliances, the first one is the Mandibular Protraction Appliances, while the second one was the PowerScope Appliance.
the treatment duration was 6 months the patients age was considered according to Baccetti et al, CVMI 3,4
