ABSTRACT:
A rigid grommet-like end-connector device for use with an end of one or more elastomeric, orthodontic, tension-applying chains of the kind having a string of plural, endless, stretchable loops. The device is primarily useful in intermaxillary-type orthodontic applications, where long-term uninterrupted usage is desired, and where it is important to provide a solid wear-resistant attaching structure for the ends of the force-applying elastomer unit. The proposed device significantly expands the utility of currently available orthodontic chains of the type generally mentioned, by permitting plural strands of these chains to be connected in parallel, so-to-speak, both to amplify force-transmission capabilities, and to enhance longevity of effective performance life.
