Title (EN) ABRASIVE DENTAL FLOSS AND METHOD OF MAKING SAME
(FR) FIL DENTAIRE ABRASIF ET SON PROCÉDÉ DE FABRICATION
Abstract: front page image
(EN) Polytetrafluoroethylene (PTFE) flosses have abrasives added to the floss fiber that increase the abrasion to teeth surfaces, and thus result in a floss that provides enhanced cleaning of surfaces of teeth that face interstices between teeth. Floss fiber is formed by loading a PTFE resin with an abrasive filler. The PTFE resin and filler are processed to form a floss fiber with a surface that provide enhanced abrasion properties.
(FR) Les fils en polytétrafluoroéthylène (PTFE) possèdent des abrasifs ajoutés à la fibre de fil, qui augmentent l'abrasion sur les surfaces des dents, et permettent ainsi d'obtenir un fil assurant un nettoyage plus efficace des surfaces des dents qui font face aux interstices entre les dents. La fibre du fil est formée en ajoutant une charge abrasive à une résine PTFE. La résine PTFE et la charge sont traitées pour former une fibre de fil dont la surface offre des propriétés abrasives améliorées.
