Abstract

An integrally formed dental floss and leader which lends itseld to oral prophylaxis especially for implants and bridges. The floss is captured by the leader through a hinged door which swings from an open to a closed position during fabrication to provide an integral unit for use by a floss user.

Claims

1. An integrally formed dental floss and leader for use with bridges, implants or other structures such as teeth and prosthodontic devices, comprising in combination:

said leader having a free end for threading into interproximal dental spaces and a tethered end which supports said floss,

said tethered end including means for fixedly prefusing said floss to said leader thereto in a manner preventing substantial sliding of said floss relative to said tethered end of said leader.

2. The device of claim 1 wherein said leader includes a tactile enchancement means on a body portion intermediate said free end and said tethered end for facilitating grasping and use of the said integral leader and floss, and wherein said leader maintains a substantially constant, low-profile cross-section such that said leader may pass entirely through any opening through which said free end of said leader may enter.

3. The device of claim 1 wherein said tethered end includes a support, a door and a hinge connecting said support to said door whereby said door swings from an open to a closed position with said floss interposed adjacent said hinge, and an adhesive interface is located between said door and said support, said support and said door being substantially planar along an interconnection interface, said interface also coplanar with a portion of said floss captured by said hinge.

4. The device of claim 3 wherein said support includes a raised bead on a base surface thereof adapted to be juxtaposed against said door, said bead being susceptible to radiation for devolution into an adhesive for sealing said door to said support.

5. The device of claim 4 wherein said hinge is embodied as a boss having a ramp communicating with said base surface at one end of said boss and another ramp communicating with said door at another end of said boss.

6. The device of claim 4 wherein said hinge is embodied as a thinned area between said support and said door defining a flexible hinge upon which said floss is supported.

7. The device of claim 4 wherein said tactile enhancement means is in the form of surface irregularities on an arcuate body portion interposed between said free end and said tethered end to assist in the grasping by one using the device.

8. The device of claim 7 wherein said hinge is in the form of a boss having a central opening passing therethrough which is transverse to a planar surface of said leader, and said floss passes through said hole in said boss.

9. The device of claim 8 wherein said boss includes first and second transitional areas, one said transitional area defining a taper and ramp which communicates with a base extending from said boss to an arcuate portion of said leader.

10. The device of claim 9 wherein said other transitional area of said boss includes a tapered ramp extending to said door.

11. The device of claim 7 wherein said hinge is formed from thin material on said leader and said floss is placed thereagainst and said door folds about an axis of said hinge which is parallel to a width of said leader.

12. The device of claim 11 where said hinge has radiused side edges against which said floss abuts for stress relief.

13. The device of claim 3 wherein ultrasonic means are interposed between said door and a base surface of said support for adhesion therebetween.

14. A method for forming a flossing device for cleaning interproximal dental spaces like spaces existing between dental bridges, implants or the like and other dental structures such as teeth and gums, the steps including:

forming a leader with a door having a hinge,

initially orienting the door in an open position,

looping a floss about the hinge of the leader door,

sealing the door shut on the floss in a manner securely capturing the floss to the leader.

15. The method of claim 14 including placing tactile enhancement means on a medial portion of said leader to assist in gripping said leader, said tactile enhancement means providing means to resist longitudinal slipping of the leader when grasped and moved by a hand of the user.

16. The method of claim 15 wherein said tactile enhancement means is evidenced by forming knurling thereon.

17. The method of claim 15 wherein said tactile enhancement means is formed by placing crenellations thereon.

18. The method of claim 15 wherein said tactile enhancement means is formed by placing protuberances thereon.

19. The method of claim 15 wherein said leader has a free end formed with an arcuate blunted leading tip portion.

20. A device for flossing dental appliances such as bridges, implants and the like, comprising in combination:

a leader having a free end and a tethered end, said tethered end including a door, and

acrylic fiber floss having a substantially uniform cross-sectional area along its length and having a plurality of outwardly extending fibrous free ends which contact and remove plaque from the dental environment, said floss connected to said tethered end via said door such that, during fabrication of said device, said floss is looped about a hinge of said door and said door is shut.

21. An integrally formed dental floss and leader for use with bridges, implants or other structures such as teeth and prosthodontic devices, comprising in combination:

said leader having a free end for threading into interproximal dental spaces and a tethered end which supports said floss,

said tethered end including means for fixedly prefusing said floss to said leader in an orientation wherein said floss adjacent said leader remains in a plane coplanar with said leader, whereby both said floss and said leader can easily pass through a narrow interproximal space.

22. The device of claim 21 wherein a hinge of said leader adjacent said floss includes stress relieving means, whereby loads between said leader and said floss are more easily maintained.

23. The device of claim 22 wherein said stress relieving means are curved corners located between an inside surface of said leader and two opposing side surfaces of said leader.
