简要总结
This study aims at evaluating the effects of mandibular advancement on pharyngeal airway space and nocturnal breathing in children with skeletal class II division1 malocclusion. Fifty patients will be enrolled in the study divided into control and experimental groups.
详细描述
The purpose of the present research is not only evaluate the effect of functional appliance on the pharyngeal airway space, but also evaluate its effect on nocturnal breathing of children with skeletal class II.
