Objective To evaluate the early clinical outcomes of the flat bite plate and divisive spring to be used for the patient of Angles II decision I. Methods Choose 35 patients whose tooth are class II , canines class II, mandibular plane angle is average angle/low angle and mandibular retrusion, Use flat bite plate and divisive spring for early treatment. Results after 1st stage treatment,anterior teeth overbite cover to reach the basic normal, molar relationship to neutral or neutral remote,surface is improved apparently,chin soft tissue thickening, mentolabial groove depth decreases, nasolabial angle change. Conclusion the improved flat bite plate appliance could improve the facial profile of the patients with Angles II division I,is a kind of safe and effective method.
