Objective:To study the possibility of treatment on class II malocclusion of mandibular retraction during growth with a new detachable headgear-activator. Methods:13 patients were studied at the mean age of 10.8 years with this appliance. Results:Dentofacial profile significantly improved,relations of class II were corrected,and occluding relations were stable after average 11 months treatment. Conclusion:The detachable headgear-activator is a feasible and very effective appliance on the early class II malocclusion of mandibular retraction. [
