Abstract: The disclosed line guides combine a wear resistant ring with a superelastic, shape memory alloy frame and support to provide a lightweight and durable assembly. The wear resistant ring is constructed of hard material such as ceramic. The wear resistant ring includes a groove or annular depression on the outside surface where the ring and frame meet. The elastic frame is configured to grip the ring, which provides an enhanced mechanical connection between the wear resistant ring and the superelastic frame. The groove also provides a location for the application of adhesive. The frame is exposed around the wear resistant ring and protects the ring from damage during storage, transportation and use. The superelastic alloy frame and support flex to absorb shock and when deformed rebound to their original shape.

Abstract: A handle for releasably retaining tubular sleeve-like crimpable stops is disclosed. The handle includes an elongated body with opposed ends and at least one receptacle positioned at one end of the body. The receptacle has an inside surface and defines an entry opening. The receptacle may be configured to mechanically retain the stop, or the stop may be releasably bonded to the receptacle by sticky substances like wax, any suitable adhesive or techniques such as heat bonding. The handle is molded from plastic in a color contrasting with the oral environment, such as orange. The handle aids in handling and positioning crimpable stops during installation of archwire assemblies in the oral environment. A stop retained in the disclosed handle is highly visible and can be handled without tools.
