Abstract

Rotating dental systems and related guards and methods are disclosed. In some instances a guard may be configured to prevent material from building up on at least a portion of the dental system. The guard may be configured to prevent materials from being discharged from the dental system. In some embodiments, the guard may also be configured to direct the flow of material along a portion of the dental system. Some guards within the scope of this disclosure comprise bristles.

First claim

We claim:

1. A rotating dental tool, comprising:
a handle;
a treatment cup coupled to the handle;
a guard coupled to the handle, the guard including a body; and
a plurality of bristles extending outwardly from an outer portion of the body of the guard, the plurality of bristles configured to interact with a discharge material on an outside surface of the treatment cup and prevent the discharge material from building up on at least a portion of the treatment cup;
wherein the outer portion of the body is spaced apart from the outside surface of the treatment cup by a distance;
wherein at least a portion of the plurality of bristles are disposed within the distance; and
wherein a first portion of the plurality of bristles extends perpendicularly from the guard and a second portion of the plurality of bristles is angled acutely with respect to the guard.

2. The rotating dental tool of claim 1 , wherein the bristles are arranged in two rows.

3. The rotating dental tool of claim 2 , wherein the bristles in a first row are staggered from the bristles in a second row.

4. The rotating dental tool of claim 1 , wherein the bristles are arranged in three rows.

5. The rotating dental tool of claim 4 , wherein the bristles are staggered from row to row.

6. The rotating dental tool of claim 1 , wherein one or more bristles of the plurality of bristles are angled towards a rim of the treatment cup.

7. The rotating dental tool of claim 1 , wherein the plurality of bristles comprises between three and eighteen bristles, inclusive.

8. The rotating dental tool of claim 1 , wherein the plurality of bristles comprises between five and eleven bristles, inclusive.

9. The rotating dental tool of claim 1 , wherein the body of the guard further comprises an elongated body member with an enlarged portion at one end and a narrow portion at an opposite end.

10. The rotating dental tool of claim 1 , wherein at least a portion of the plurality of bristles conforms to a contour of the outside surface of the treatment cup.

11. A discharge guard for a rotating dental tool, the discharge guard comprising:
a body member; and
a brush coupled to the body member, the brush extending outwardly from an outer portion of the body member, the brush configured to interact with a discharge material on an outside surface of a treatment cup of the rotating dental tool and prevent the discharge material from building up on at least a portion of the treatment cup;
wherein the outer portion of the body member is spaced apart from the outside surface of the treatment cup by a distance;
wherein at least a portion of the brush is disposed within the distance; and
wherein the brush comprises a plurality of bristles, a first portion of the plurality of bristles extends perpendicularly from the body member and a second portion of the plurality of bristles is angled acutely with respect to the body member.

12. The discharge guard of claim 11 , wherein the brush comprises a plurality of bristles, the bristles are arranged in two rows.

13. The discharge guard of claim 12 , wherein the brush comprises a plurality of bristles, the bristles in a first row are staggered from the bristles in a second row.

14. The discharge guard of claim 11 , wherein the brush comprises a plurality of bristles, the bristles are arranged in three rows.

15. The discharge guard of claim 14 , wherein the brush comprises a plurality of bristles, the bristles are staggered from row to row.

16. The discharge guard of claim 11 , wherein one or more bristles of the plurality of bristles are angled towards a rim of the treatment cup.

17. The discharge guard of claim 11 , wherein the brush comprises a plurality of bristles, the plurality of bristles comprises between three and eighteen bristles, inclusive.

18. The discharge guard of claim 11 , wherein the brush comprises a plurality of bristles, the plurality of bristles comprises between five and eleven bristles, inclusive.

19. The discharge guard of claim 11 , wherein the body member is elongated and has an enlarged portion at one end and a narrow portion at an opposite end.

20. The discharge guard of claim 11 , wherein the brush comprises a plurality of bristles, at least a portion of the plurality of bristles is configured to conform to a contour of the outside surface of the treatment cup.
