ABSTRACT:
The wire of an orthodontic appliance is attached at either end to a tooth by means of a lock secured to a band passed around the tooth and having a U-shaped recess into which a retaining spring is set so that when the latch holding the wire is inserted, the ends of the spring catch in notches on the latch thereby affording secure attachment and easy removal and replacement of the wire.
