Title: Ingredient filled polytetrafluoroethylene dental floss
Inventor: CURTIS JOHN
IPC: A61Q11/00
Filed: 1997-06-18
Granted: 2008-02-05
Abstract: The floss is comprised of one or more strands of a tensilized polytetrafluoroethylene. The polytetrafluoroethylene is tensilized by stretching with heating to increase the tensile strength and to decrease elongation. The floss is readily grippable since it has an irregular surface. The polytetrafluoroethylene is made to have an irregular surface by having a solid incorporated into the fiber structure. The solid has a diameter of from about submicron size up to about 125 % of the thickness diameter of the fiber. The floss will have a coefficient of friction of more than about 0.08. There is an acceptable grippability without the need for a coating. In addition, the solid that is incorporated into the fiber can be a bioactive material for delivery of the bioactive material to the teeth and gums during flossing.
