Abstract
Abstract A torquing spring formed of a wire loop having the top of its central portion adapted to engage the labial surface of the tooth and continuing into a pair of vertically extending legs. Each leg terminates at a pair of axially contiguous coil-sets. One of the coil sets associated with each leg is unrestricted, while the other of the coil-sets associated with each leg is bound to the base arch wire.
