Abstract

A teeth cleaning system, which provides improved coverage or brushing area. The system includes an actuated tray comprises brushing elements. The brushing elements may be positioned to engage the front, rear, and top surfaces of the upper and lower jaw teeth. The actuation may be configured to oscillate the tray in a lateral direction which may brush all the surfaces of teeth simultaneously. Some embodiments include a higher density of bristles which increases the effectiveness of brushing. In addition, aspects of the system reduce the time spent brushing teeth.

Claims (69)

1. A teeth cleaning system, comprising:

an arcuate tray configured to receive a set of teeth, wherein the arcuate tray includes:

an inner arcuate wall,

an outer arcuate wall,

a baffle positioned transversely across between an inner surface of the outer arcuate wall and an inner surface of the inner arcuate wall and defining an upper channel for receiving teeth of an upper jaw and defining a lower channel for receiving teeth of a lower jaw, and

a plurality of bristles positioned in the upper channel and in the lower channel;

a connector that is coupled to an outer surface of the outer arcuate wall of the arcuate tray, wherein the connector has an inner surface that defines a cavity and a mating element that is positioned within the cavity; and

a handle that includes:

a shaft that is covered by a sleeve, wherein the sleeve is detachably receivable within the cavity defined by the inner surface of the connector and the shaft is detachably receivable by the mating element of the connector;

a motor, and

an oscillator configured to move the arcuate tray side-to-side along a same plane as the baffle by moving the shaft side-to-side in response to operation of the motor.

2. The teeth cleaning system of claim 1 , wherein the bristles are positioned on:

a top surface and a bottom surface of the baffle,

the inner surface of the inner arcuate wall, and

the inner surface of the outer arcuate wall.

3. The teeth cleaning system of claim 1 , wherein the outer arcuate wall comprises an outer shell configured to detain the inner surface of the outer arcuate wall.

4. The teeth cleaning system of claim 3 , wherein:

the outer shell is a first plastic material, and

the inner surface of the outer arcuate wall is a second plastic material, wherein the second plastic material is firmer than the first plastic material.

5. The teeth cleaning system of claim 3 , wherein the inner surface of the outer arcuate wall includes spaced slots disposed to provide flexure in the outer arcuate wall.

6. The teeth cleaning system of claim 1 , wherein the inner arcuate wall includes an outer shell configured to detain the inner surface of the inner arcuate wall.

7. The teeth cleaning system of claim 6 , wherein:

the outer shell is a first plastic material, and

the inner surface of the outer arcuate wall is a second plastic material, wherein the second plastic material is firmer than the first plastic material.

8. The teeth cleaning system of claim 1 , further comprising:

a cam coupled between the motor and the shaft, wherein the cam is configured to engage a bottom end of the shaft, so as to move the shaft side-to-side in response to the motor rotating the cam.

9. The teeth cleaning system of claim 8 , further comprising a guide plate that has an aperture defined therein, wherein a side-to-side range of the shaft is limited by a width of the aperture.

10. A teeth cleaning system, comprising:

an arcuate tray configured to receive a set of teeth, wherein the arcuate tray includes:

an inner arcuate wall,

an outer arcuate wall,

baffle positioned transversely across between an inner surface of the outer arcuate wall and an inner surface of the inner arcuate wall and defining an upper channel for receiving teeth of an upper jaw and defining a lower channel for receiving teeth of a lower jaw, and

a plurality of bristles positioned in the upper channel and in the lower channel, wherein the plurality of bristles comprises a density of between 324 bristles per cm 2 -646 bristles per cm 2 ;

a connector, that is coupled to an outer surface of the outer arcuate wall of the arcuate tray; and

a handle that includes:

a shaft that is detachably receivable by the connector,

a motor with a drive shaft that rotates during operation,

a cam to which the shaft and the drive shaft of the motor are coupled, wherein the cam is configured to move the shaft side-to-side in response to the drive shaft of the motor rotating the cam, and

a guide plate with an aperture defined therein, wherein a range of side-to-side movement of the shaft is limited by a width of the aperture.

11. The teeth cleaning system of claim 10 , wherein the bristles are positioned on:

a top and bottom surface of the baffle,

the inner surface of the inner arcuate wall, and

the inner surface of the outer arcuate wall.

12. The teeth cleaning system of claim 11 , wherein:

the bristles on the inner surface of the inner arcuate wall, and on the inner surface of the outer arcuate wall project at an acute angle from their respective inner surface relative to a plane of the baffle.

13. The teeth cleaning system of claim 11 , wherein the top and bottom surface of the baffle, the inner surface of the inner arcuate wall, and the inner surface of the outer arcuate wall each include a plurality of receptacles and wherein the plurality of bristles are positioned in bundles in respective receptacles.

14. The teeth cleaning system of claim 13 , wherein the top surface, the bottom surface, or the baffle include 7.72 holes per cm 2 to 15.38 holes per cm 2 for holding the bristles.

15. The teeth cleaning system of claim 10 , wherein:

the inner surface of the outer arcuate wall includes first spaced slots disposed to provide flexure in the outer arcuate wall; and

the inner surface of the inner arcuate wall includes second spaced slots disposed to provide flexure in the outer arcuate wall.

16. A teeth cleaning system, comprising:

an arcuate tray configured to receive a set of teeth, wherein the arcuate tray includes:

an inner arcuate wall,

an outer arcuate wall,

a baffle positioned transversely across between an inner surface of the outer arcuate wall and an inner surface of the inner arcuate wall and defining an upper channel for receiving teeth of an upper jaw and defining a lower channel for receiving teeth of a lower jaw, and

a plurality of bristles positioned in the upper channel and in the lower channel, wherein the plurality of bristles comprise a density between 324 bristles per cm 2 -646 bristles per cm 2 , wherein a top surface of the baffle and a bottom surface of the baffle, the inner surface of the inner arcuate wall, and the inner surface of the outer arcuate wall each include a plurality of receptacles and wherein the plurality of bristles are positioned in bundles in respective receptacles;

a connector that is coupled to an outer surface of the outer arcuate wall of the arcuate tray; and

a handle that includes:

a casing,

a motor with a drive shaft that rotates during operation, and

an oscillator assembly that includes:

a shaft that protrudes from a top end of the casing and is engageable with the connector, and

a cam to which the shaft and the drive shaft of the motor are coupled, wherein the cam is configured to move the shaft side-to-side along a same plane as the baffle in response to the drive shaft of the motor rotating the cam.
