Abstract

Frankel II appliance has been one of the most commonly used appliances in treating class II malocclusions with retrognathic mandible. For step wise advancement, clinicians usually follow the conventional method suggested by Rolf Frankel by splitting the buccal shields and advancing the lower labial pads and lingual pads as a unit, followed by re-acrylisation or by fabrication of a new appliance. The modified Frankel II appliance is constructed by incorporating two orthodontic expansion screws on either side of the buccal shields of Frankel II during the fabrication of the appliance. Activation of the expansion screws will help in advancing the lower lingual pad and the labial pads as a unit therefore offering several significant advantages over the previously used technique.
