  • Curved elastomeric orthodontic ligature
    Patent number: 6280186
    Abstract: An elastomeric orthodontic ligature for engagement with a tooth-mounted orthodontic appliance such as a bracket having conventional tie wings. In one application, the ligature is engaged behind and between upper and lower tie wings of the bracket, and extends over the bracket surface to hold an archwire in a slot of the bracket. The ligature differs from known elastic ligatures of flat torus shape in that it is arched or curved to simplify and speed initial engagement behind one of the bracket tie wings.
