Abstract

Flexible probing elements (4.1, . . . , 4.6) with different diameters are guided into an interdental space for determining a proximal allowance of the interdental space. The proximal allowance is determined according to the parameter values that correspond to the probing element that just barely fits through the interdental space. The probing elements (4.1, . . . , 4.6) can be realized on a probing tip (3) with a diameter that changes continuously or in a stepwise manner. The determination of the proximal allowance makes possible for an adviser to determine in an exact and reproducible manner the optimum interdental brush for the user.

Claims

1. A dental hygiene system comprising:

at least one interdental probe for measuring an interdental space, said interdental probe including a flexible probe tip divided into a plurality of segments, each segment having a respective characteristic diameter, the system further comprising a plurality of said interdental brushes, each said interdental brush being associated with a respective said segment of said flexible probe tip; and

at least one interdental brush associated with said characteristic diameter of said interdental probe.

2. The system according to claim 1, wherein said flexible probe tip is made from a substantially incompressible material.

3. The system according to claim 1, wherein said plurality of segments decrease in diameter in a direction towards a distal end of said probe tip.

4. The system according to claim 3, wherein said plurality of segments decrease stepwise in diameter.

5. The system according to claim 3, wherein said plurality of segments decrease continuously in diameter.

6. The system according to claim 1, comprising a handle member, said flexible probe tip being mounted on an end of said handle member.

7. The system according to claim 6, comprising two said flexible probe tips mounted on opposite ends of said handle member.

8. The system according to claim 6, wherein said flexible probe tip is replaceably mounted on said handle member.

9. The system according to claim 1, wherein said flexible probe tip is made from a flexible plastic.

10. The system according to claim 9, wherein said flexible probe tip is made from a polyamide.

11. The system according to claim 1, wherein said plurality of segments are color-coded with respect to their respective diameters.

12. The system according to claim 1, wherein said probe comprises a flexible probe tip having a single characteristic diameter.

13. The system according to claim 12, wherein said flexible probe tip is made from a substantially incompressible material.

14. The system according to claim 12, comprising a handle member, said flexible probe tip being mounted on an end of said handle member.

16. The system according to claim 14, comprising two said flexible probe tips mounted on opposite ends of said handle member.

17. The system according to claims 16, wherein one said flexible probe tip has a different characteristic diameter from the other said probe tip.

18. The system according to claim 12, wherein said flexible probe tip is made from a flexible plastic.

19. The system according to claim 12, wherein said flexible probe tip is color-coded in accordance with said single characteristic diameter thereof.

20. The system according to claim 1, wherein each said segment is color-coded so as to correspond with a respective said interdental brush.

15. The system according to claimed 14, wherein said flexible probe tip is replaceably mounted on said handle member.
