Abstract

A light curing impression system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure impression material. The light curing impression system generally includes an LED light source, a light emitting impression tray, an activation module and impression material.

First claim

We claim:

1. A dental tray system comprising:
a dental tray having a body having at least one channel for receiving a quantity of photocurable dental material and a light conductor, and
a light engine having at least one battery or is connectable to an electrical power source and at least one light source,
wherein the light source is capable of connecting to the dental tray such that the light source is optically coupled to the light conductor,
wherein said light conductor extends along said body of the dental tray and is oriented toward the internal and external portion of a dental arch to allow for adequate curing of the dental material in the body and the dental material that overflows outside the body,
wherein the light conductor is a light pipe,
wherein the body has an upper portion and a lower portion, and the light pipe is sandwiched between the upper portion and lower portion, and
wherein the upper portion and lower portion are integrally connected to each other such that the upper portion and lower portion will not separate, and
wherein the upper portion includes mechanical retaining features at a bottom of the upper portion that in combination with walls of the dental tray are capable of retaining a majority of the photocurable dental material within the dental tray.

2. The dental tray system of claim 1 , wherein the dental tray is reusable.

3. The dental tray system of claim 2 , wherein the dental tray further includes a liner that is pre-filled with the photocurable dental material and the liner is placed into the channel.

4. The dental tray system of claim 2 , where the dental tray is autoclavable.

5. The dental tray system of claim 1 , wherein the dental material tray is disposable.

6. The dental tray system of claim 1 , wherein the light source is directly coupled to or is in direct contact with the light conductor.

7. The dental tray system of claim 1 , wherein the light source is not in direct contact with the light conductor.

8. The dental tray system of claim 1 , wherein the light pipe is capable of transmitting light from the light source to the photocurable dental material.

9. The dental tray system of claim 8 , wherein the photocurable dental material is activated upon exposure to the light and is cured.

10. The dental tray system of claim 1 , wherein the at least one light source is a light emitting diode.

11. The dental tray system of claim 1 , wherein the light engine is rechargeable.

12. The dental tray system of claim 1 , wherein the dental tray is a single arch tray.

13. The dental tray system of claim 1 , wherein the dental material tray is a double arch tray.

14. The dental tray system of claim 13 , wherein the double arch tray includes two channels.

15. The dental tray system of claim 14 , wherein the light conductor is placed between the two opposing channels.

16. The dental tray system of claim 14 , wherein a spacer is placed between the two channels.

17. The dental tray system of claim 16 , wherein the spacer is a translucent occlusal substrate.

18. The dental tray system of claim 1 , wherein the body further includes dispersing features that assist the light conductor in dispersing light throughout the photocurable dental material.

19. The dental tray system of claim 1 , wherein the dental tray is configured to place and bond preformed orthodontic wire and bracket assemblies onto teeth.

20. The dental tray system of claim 1 , wherein the dental tray is configured to place a photoactivated solution onto a patient's teeth and then apply the appropriate wavelength to a location where the solution was placed.

21. The dental tray system of claim 1 , wherein the light pipe is a plastic molded light pipe.

22. The dental tray system of claim 1 , wherein the mechanical retaining features are holes, dovetail slots, or T-slots.

23. The dental tray system of claim 1 , wherein the mechanical retaining features form a retentive layer at the bottom of the upper portion.
