ABSTRACT:
An orthodontic spring appliance which is readily inserted in the mouth and may be stretched to exert a predetermined force is provided by a coil spring having on at least one end a substantially straight wire having protrusions thereon spaced at predetermined intervals. The wire with protrusions may be readily connected to a spring clip which may be attached to the arch wire or a tooth bracket. The clip has a slot therein which is so designed that it readily accommodates the protrusion but prevents the wire from being pulled out by the tension force of the spring.
