Abstract
Abstract An extra oral force spring attachment comprising a coil spring and a tubular retainer affixed near each end of an extra oral arch wire. The tubular retainer is endwardly open to receive one end of the spring and is treated to retain the spring. Each end of the arch wire is measured and cut to precisely fit within the buccal tube of a tooth band when the spring is compressed against the tube.
