  • Patent number: 4817643
    Abstract: A dental floss woven in a chinese finger cuff pattern is provided. The dental floss is woven with a sufficient number of fibers to be self-supporting. The chinese finger cuff weave allows for constriction of the dental floss about its longitudinal axis when tension is applied in the longitudinal direction. The hollow cylinder defined by the chinese finger cuff weave may be filled with fluoride or other cleaning substances such that when the dental floss has longitudinal tension applied to it the fluoride is released. The interstitial spaces between the fibers provides for a trapping action of food particles when longitudinal tension is applied.
