ABSTRACT:
An orthodontic elastic appliance for use with an orthodontic bracket means which defines a channel, or for use directly on teeth, comprises a plurality of closed loops of elastic material interconnected by elastic connecting means coupled between adjacent closed loops. The closed loops are provided with engaging means on a surface thereof, the engaging means being dimensioned and shaped such that when a loop is stretched and is at least partially engaged with a bracket and/or a tooth, the engaging means abuttingly engages at least a portion of an engaging and retaining surface of a bracket, or at least a portion of the tooth, to substantially prevent the engaged elastic loop from shifting its position relative to the bracket means or tooth on which it is mounted.
