Abstract

A device for abrading or polishing primarily uneven objects, comprising an abrasive section in the form of a strip which is preferably essentially in-elastic and which is coated with an abrasive or polishing layer. One end of the ribbon shows an elastic section connected to the abrasive section. Such a device allows a reciprocating movement without moving the end of the ribbon which is inserted into the mouth of the patient.

Claims

1. A device which may be resiliently extended in use for abrading tooth surfaces, said device comprising:

an abrasive section in the form of a strip, which is substantially inelastic in a longitudinal direction, and which is coated with an abrasive layer; and

an elastic section connected to the abrasive section at one end and which may be held stationary at the other end thereof.

2. A device according to claim 1, wherein the elastic section has a structured surface.

4. A device according to claim 1, wherein the elastic section is an elastic O-ring, connected to the ribbon and serving as holding means.

5. A device according to claim 1, wherein a holding means is connected to a second end of the abrasive section.

8. A device according to claim 1, wherein the abrasive section consists of a non-elastic material.

16. A device according to claim 1, wherein the elastic section comprises a tension spring.

17. A device according to claim 5, wherein the holding means includes a tapered pin.

3. A device for abrading mainly uneven objects, comprising an abrasive section in the form of a strip, which is substantially inelastic in a longitudinal direction of the strip, and which is coated with an abrasive layer, wherein a first end of the device is provided with an elastic section which is connected to a first end of the abrasive section, wherein the elastic section is made of a material selected from the group consisting of rubber and elastomer.

6. A device which may be resiliently extended in use for abrading mainly uneven objects said device comprising:

an abrasive section in the form of a strip, which is substantially inelastic in a longitudinal direction and which is coated with an abrasive layer; and

an elastic section connected to the abrasive section at one end and which may be held stationary at the other end thereof,

wherein a holding means is connected to the other end of the abrasive section and, wherein the holding means includes a loop.

7. A device which may be resiliently extended in use for abrading mainly uneven objects, said device comprising:

an abrasive section in the form of a strip, which is substantially inelastic in a longitudinal direction, and which is coated with an abrasive layer; and

an elastic section connected to the abrasive section at one end and which may be held stationary at the other end thereof,

wherein a holding means is connected to the other end of the abrasive section and, wherein the holding means includes a cylindrical pin.

9. A device which may be resiliently extended in use for abrading mainly uneven objects said device comprising:

an abrasive section in the form of a strip, which is substantially inelastic in a longitudinal direction, and which is coated with an abrasive layer; and

an elastic section connected to the abrasive section at one end and which may be held stationary at the other end thereof,

wherein the abrasive section consists of a non-elastic material and, wherein the abrasive section comprises a window without abrasive layer.

10. A device which may be resiliently extended in use for abrading mainly uneven objects, said device comprising:

an abrasive section in the form of a strip, which is substantially inelastic in a longitudinal direction, and which is coated with an abrasive layer; and

an elastic section connected to the abrasive section at one end and which may be held stationary at the other end thereof, wherein the material in a substrate of the abrasive section is selected from the group consisting of plastic, metal and card.

11. A device for abrading mainly uneven objects, comprising an abrasive section in the form of a strip, which is substantially inelastic in a longitudinal direction of the strip, and which is coated with an abrasive layer, wherein a first end of the device is provided with an elastic section which is connected to a first end of the abrasive section, wherein the device comprises at a second end a loop for receiving a spindle and at the first end the elastic means comprising a holding means.

12. The device of claim 11 in combination with a dentist apparatus, the dentist apparatus including the spindle having a receiving end with a receiving piece having a central axis which is eccentric in regard to a central axis of the spindle and has a smaller diameter than the spindle, wherein the second end of the device engages the receiving end of the spindle.

13. The device according to claim 12, wherein a surface of the receiving piece of the spindle is concave.

14. A device which may be resiliently extended in use for abrading mainly uneven objects, said device comprising:

an abrasive section in the form of a strip, which is substantially inelastic in a longitudinal direction, and which is coated with an abrasive layer; and

an elastic section connected to the abrasive section at one end and which may be held stationary at the other end thereof, wherein the elastic section is made of rubber.

15. A device which may be resiliently extended in use for abrading mainly uneven objects, said device comprising:

an abrasive section in the form of a strip, which is substantially inelastic in a longitudinal direction, and which is coated with an abrasive layer; and

an elastic section connected to the abrasive section at one end and which may be held stationary at the other end thereof, wherein the elastic section is made of elastomer.

18. A device for abrading tooth surfaces, comprising an abrasive section in the form of a strip, which is substantially inelastic in a longitudinal direction of the strip, and which is coated with an abrasive layer, wherein a first end of the device is provided with an elastic section which is connected to a first end of the abrasive section, wherein the elastic section comprises a tension spring.

19. A device which may be resiliently extended in use for polishing tooth surfaces, said device comprising:

a polishing section in the form of a strip, which is substantially inelastic in a longitudinal direction, and which is coated with a polishing layer,

an elastic section connected to the polishing section at one end and which may be held stationary at the other end thereof.

21. A device according to claim 19, wherein the elastic section comprises a tension spring.

20. A device which may be resiliently extended in use for polishing mainly uneven objects, said device comprising:

a polishing section in the form of a strip, which is substantially inelastic in a longitudinal direction, and which is coated with a polishing layer; and

an elastic section connected to the polishing section at one end and which may be held stationary at the other end thereof, wherein the elastic section is made of a material selected from the group consisting of rubber and elastomer.
