Abstract

An intraoral apparatus for illuminating a patient'"'"'s mouth includes a bite spacer having a pair of teeth engaging structures vertically spaced apart by a spacer structure that includes a side wall. At least one self-contained light emitting device is operably mounted in the side wall of the bite spacer. The bite spacer is positionable between the teeth on either side of the patient'"'"'s mouth such that the light emitting devices illuminate the other side of the patient'"'"'s mouth. In one embodiment, a rechargeable battery is positioned within the bite spacer to power the light emitting devices. An induction charging circuit recharges the rechargeable battery without connections external to the bite spacer. In another embodiment, the bite spacers are adapted to interface with a recharging and sterilizing base station.

Claims

1. An intraoral apparatus for illuminating a patient'"'"'s mouth comprising:

a bite spacer having a pair of teeth engaging structures vertically spaced apart by a spacer structure that includes a side wall;

at least one self-contained light emitting device operably mounted in the side wall; and

a battery source positioned within the bite spacer and providing electrical power to the plurality of light emitting device,

whereby the bite spacer is positionable between the teeth on either side of the patient'"'"'s mouth such that the light emitting devices illuminate the other side of the patient'"'"'s mouth.

2. The apparatus of claim 1, wherein the light emitting device is a light emitting diode.

3. The apparatus of claim 1, wherein the battery source is a rechargeable battery.

4. The apparatus of claim 3, further comprising an induction charging circuit positioned within the bite spacer and electrically connected to the rechargeable battery such that the rechargeable battery is rechargeable without connections external to the bite spacer.

5. The apparatus of claim 1, wherein the battery source and the light emitting device is sealed within the bite spacer.

6. The apparatus of claim 1, wherein the teeth retaining structures include a pair of generally U-shaped channels.

7. The apparatus of claim 6, wherein the U-shaped channels are symmetrically angled from a front end to a rear end of the bite spacer.

8. The apparatus of claim 1, further comprising a waterproof power switch mounted in the bite spacer and electrically coupled between the battery power source and the light emitting devices.

9. The apparatus of claim 1, wherein there are a plurality of light emitting devices and at least one of the light emitting devices emits light at a frequency range that does not activate photopolymerizable materials.

10. The apparatus of claim 9, further comprising a waterproof power switch mounted in the bite spacer and electrically coupled between the battery power source and the light emitting devices that selectively activates the at least one light emitting device that emits light at the frequency range that does not activate photopolymerizable materials.

11. The apparatus of claim 1, further comprising means electrically coupled to the battery power source for indicating a low battery charge.

12. The apparatus of claim 1 wherein the battery power source and the light emitting devices are selected such that the battery power source has a capacity to illuminate the light emitting devices for a period of at least one-half hour with a luminous intensity of at least 50 lumens and without causing the apparatus to rise in temperature significantly above human body temperature.

18. The apparatus of claim 1 wherein the rechargeable battery and the at least one light emitting device are selected such that the battery power source has a capacity to illuminate the light emitting devices for a period of at least one-half hour with a luminous intensity of at least 50 lumens and without causing the apparatus to rise in temperature significantly above human body temperature.

13. An intraoral apparatus for illuminating a patient'"'"'s mouth comprising:

a bite spacer having a pair of teeth engaging structures vertically spaced apart by a spacer structure that includes a side wall;

at least one self-contained light emitting device operably mounted in the side wall;

a rechargeable battery positioned within the bite spacer and providing electrical power to the at least one light emitting device; and

an induction charging circuit positioned within the bite spacer and electrically connected to the rechargeable battery,

such that the rechargeable battery is rechargeable without connections external to the bite spacer.

14. The apparatus of claim 13, wherein the bite spacer is made of medical grade polymer and the rechargeable battery, the charging circuit and the at least one light emitting device are sealed within the bite spacer.

15. The apparatus of claim 13, further comprising a waterproof power switch mounted in the bite spacer and electrically coupled between the battery and the at least one light emitting device.

16. The apparatus of claim 13, wherein the teeth retaining structures include a pair of generally U-shaped channels.

17. The apparatus of claim 16, wherein the U-shaped channels are symmetrically angled from a front end to a rear end of the bite spacer.
