ABSTRACT:
An orthodontic bracket in which the archwire is locked in place by a resilient locking loop member which snaps into and out of engagement over the bracket. The locking loop member is a nickel-titanium wire of high resilience and shape memory which not only locks in the archwire but imparts force against it as a function of the shape memory of the locking loop member.
