Deskripsi
Anchorage control during the correction of severely crowded dentitions has always been a source of concern during orthodontic therapy. The Nance palatal arch (NPA) has, in the past, been widely used for reinforcing anchorage in such cases. Modifications of the NPA have been reported for use as a fixed functional appliance or for molar distalization. Herein, a simple, effective modification of the conventional NPA is introduced incorporating two power arms, which can be used for unravelling of anterior crowding at the same time effectively augmenting molar anchorage.
