Abstract

The light curing devices of the invention are configured with a light applicator and one or more detachable power supply units. The light applicator is configured to emit radiant energy that is suitable to cure photo-sensitive compounds. The light applicator is also configured to be detached from the detachable power supply and to be autoclaved. The detachable power supply units are configured to provide power to the light applicator and may comprise a power cord or a battery pack that is configured in size and shape to be held within the holding slot of a holding tray, an example of which is a standard dental hand piece holding tray.

Claims

1. A relatively light weight, hand-held dental device for curing light-curing compounds, and that is adapted for use in a system that includes a holding fray comprising one or more recesses, at least one of which is for receiving the dental device so as to hold the dental device in a convenient, generally upright fashion for easy grasping, the dental device comprising:

body means for defining a generally elongated, light-weight, slender body for enabling the dental device to be held and easily rotated into various positions when using the dental device for curing procedures in a patient'"'"'s mouth, and said body means also comprising means for controlling application of power;

means, disposed at a first end of the body means, for emitting radiant energy directly to a light-curable compound within a patient'"'"'s mouth, said radiant energy being suitable for curing light-curable dental compounds;

power means, disposed at a second end of the body means, for providing power to the means for emitting radiant energy, and said means for providing power also comprising means that adapts the dental device for securely sitting in an essentially elongated, upright fashion within the at least one recess of the holding tray when it is not in use; and

detachment means for detachably connecting the means for emitting radiant energy to the power means so that the means for emitting radiant energy can be selectively detached from the body means for autoclaving.

2. A dental device as recited in claim 1, comprising at least one of polysulphone or polyphenylsulphone.

3. A dental device as recited in claim 1, said means for controlling application of power comprising a control panel with controls for operating the means for emitting radiant energy.

4. A dental device as recited in claim 1, wherein the control panel is disposed on said detachment means.

5. A dental device as recited in claim 1, wherein said detachment means comprises latches configured to mechanically latch the power means to said body means.

6. A dental device as recited in claim 1, wherein said means for emitting radiant energy comprises at least one LED or LED array.

7. A dental device as recited in claim 1, wherein said power means comprises a power cord.

8. A dental device as recited in claim 7, wherein the power cord is configured to receive power from a remote power supply.

9. A dental device as recited in claim 1, wherein said power means comprises a battery pack.

10. A dental device as recited in claim 1, wherein said power means includes a plurality of detachable power supply units configured to provide power to the light applicator and that are interchangeable with each other.

11. A dental device as recited in claim 1, wherein the dental device is configured to withstand temperatures of at least 130°

C. during autoclaving.

12. A dental device as recited in claim 1, said means for controlling application of power comprising a control panel with controls for operating the dental device, the control panel being sealed to the body means.

13. A dental device as defined in claim 1, wherein said detachment means is situated between said means for emitting radiant energy and said body means so that said means for emitting radiant energy is detachable from both said body means and said power means for autoclaving separate therefrom.

14. A dental device as defined in claim 1, wherein said detachment means is situated between said body means and said power means so that said body means and said means for emitting radiant energy are detachable as a single unit for autoclaving separate from said power means.

15. A dental device as defined in claim 1, wherein said detachment means includes electrical pins disposed on the power means and corresponding electrical receptacles on said body means.
