Abstract
A loop is formed by a bow having across one side a strip or blade. The bow has flexure and memory. The flexure and memory of the bow are imparted to the strip, enabling the strip to be either taut or loose, depending on the pressure exerted by the operator upon the bow. The bow is held and manipulated by the operator with the thumb and finger. The strip is positioned under tension. A holder for the device allows additional variability in the angle of attack of the strip, and facilitates quick and easy interchange of the strips. A holder avoids insertion of fingers far back in the mouth, where working space is limited.
Claims22
A loop that is introduced into an interproximal space between teeth, said loop comprising
- a semi-annular bow having a center member that connects a generally vertical leg on a proximal end of said bow with a generally vertical leg on a distal end of said bow, said bow having a wing extending outwardly from said generally vertical leg on said proximal end of said bow and said bow having a wing extending outwardly from said generally vertical leg on said distal end of said bow;
- and
- a strip that is insertible into an interproximal space between adjacent teeth, wherein said strip is attached to at least one of said generally vertical leg on said proximal end of said bow and said generally vertical leg on said distal end of said bow, and wherein said strip has a base end and an exposed end for insertion in an interproximal space between adjacent teeth, the base end pivotally connected to the proximal end, the distal end adapted to secure the exposed end upon insertion of the exposed end between predetermined adjacent teeth;
- wherein said bow is flexible and has memory, and wherein said bow is capable of deformation by application of manual force applied to said wing extending outwardly from said generally vertical leg on said proximal end of said bow and said wing extending outwardly from said generally vertical leg on said distal end of said bow, and upon manual deformation of said bow, said strip is selectively loosened within said bow to adapt to a non-linear contour of a tooth, and upon the release of manual deformation of said bow, said strip becomes taut within said bow to facilitate removal of said strip from said interproximal space between adjacent teeth.

- a semi-annular bow having a center member that connects a generally vertical leg on a proximal end of said bow with a generally vertical leg on a distal end of said bow, and
- a strip that is insertible into an interproximal space between adjacent teeth, wherein said strip is attached to at least one of said generally vertical leg on said proximal end of said bow and said generally vertical leg on said distal end of said bow;
- wherein said bow is flexible and has memory, and wherein said bow is capable of deformation by application of manual force applied to said bow, and upon manual deformation of said bow, said strip is selectively loosened within said bow to adapt to a non-linear contour of a tooth, and upon the release of manual deformation of said bow, said strip becomes taut within said bow to facilitate removal of said bow from said interproximal space between adjacent teeth
- wherein said center member is bowable, and a center portion of said center member deforms arcuately and bows outwardly and away from a palm of a hand of a user as manual pressure is applied to squeeze and deform said bow, and said generally vertical leg on said proximal end and said generally vertical leg on said distal end of said semi-annular bow are moved in a relative direction that is opposite a direction of movement of said center portion of said center member as manual pressure is applied to squeeze and deform said bow.
