ABSTRACT:
The invention provides a new orthodontic device for use with the arch wire that is employed in an orthodontic procedure to connect together the orthodontic brackets attached to the teeth. The device comprises a core member having an axial bore to permit it to be threaded onto the wire, the external face of the core member being frustro-conical. The core member is pressed axially into a cylindrical sleeve having a tapered inner face complementary to the core frustro-conical outer face, and the core has a longitudinal slit in its circumference extending from the outer face to the bore so that as it is forced into the sleeve it can clamp tightly onto the wire. The device preferably is used with special pliers having ends which are slotted to fit over the wire and recessed to embrace the device, so that as the pliers ends are closed together the core is forced into the sleeve. The device can be used per se as an end stop, e.g. to stop relative axial movements between the wire and a bracket. A number of different members can be attached to the exterior of the sleeve so as to be fastened by the device to the arch wire, such as an elastic-engaging hook, a tooth-engaging torquing device, a spring device, and a Herbst appliance.
