Abstract

A dental apparatus is disclosed. The dental apparatus can comprise a pressure wave generator to be disposed at a treatment region of a tooth. The pressure wave generator can include an opening to deliver a flowable filling material to the treatment region. The apparatus can include a reservoir for supplying the filling material to the pressure wave generator. The pressure wave generator can be configured to generate pressure waves through the treatment region to cause the filling material to substantially fill the treatment region.

Claims

1. A dental apparatus comprising:

a handpiece having a distal portion to be positioned at a treatment region of a tooth, the handpiece further comprising a first fluid supply line and a second fluid supply line to deliver fluid to the treatment region; and

a pressure wave generator configured to generate pressure waves through the treatment region to cause a filling material to substantially fill the treatment region,

wherein the apparatus is configured to deliver a first composition through the first fluid supply line and a second composition through the second fluid supply line to the treatment region, and

wherein the apparatus is further configured to combine the first composition with the second composition at a location in the handpiece or at the treatment region of the tooth to form the filling material to substantially fill the treatment region.

2. The dental apparatus of claim 1, wherein the pressure wave generator comprises a first pressure wave generator in communication with the first fluid supply line and a second pressure wave generator in communication with the second fluid supply line.

3. The dental apparatus of claim 1, further comprising a console to be in fluid communication with the handpiece, the console comprising one or more pumps to drive the first and second compositions to the handpiece.

4. The dental apparatus of claim 3, wherein the console comprises a controller configured to change the handpiece from a cleaning mode to a filling mode or from the filling mode to the cleaning mode.

5. The dental apparatus of claim 3, wherein the console comprises one or more reservoirs to store the first and second compositions.

6. The dental apparatus of claim 1, wherein the handpiece comprises one or more reservoirs to store the first and second compositions.

7. The dental apparatus of claim 6, wherein the one or more reservoirs is disposed in or on the handpiece.

8. The dental apparatus of claim 7, wherein the one or more reservoirs is removable from the handpiece.

9. The dental apparatus of claim 1, further comprising an interface member configured to couple to a conduit in fluid communication with a console, the handpiece configured to removably engage with a distal portion of the interface member.

10. The dental apparatus of claim 9, further comprising a cartridge configured to couple with the distal portion of the interface member, the handpiece configured to removably engage with a distal portion of the cartridge, the cartridge comprising one or more reservoirs configured to store the first and second compositions.

11. The dental apparatus of claim 10, wherein the cartridge is configured to removably engage with the interface member.

12. The dental apparatus of claim 10, wherein the cartridge comprises a supply line, the supply line coiled within the cartridge.

13. The dental apparatus of claim 1, wherein the pressure wave generator comprises a liquid jet device.

14. The dental apparatus of claim 13, wherein the liquid jet device comprises a guide tube and an opening disposed near a distal portion of the guide tube.

15. The dental apparatus of claim 1, further comprising a cap near the pressure wave generator, the cap at least partially defining a chamber, the cap configured to retain fluid in the chamber when the cap is positioned against the treatment region.

16. The dental apparatus of claim 1, wherein the pressure wave generator is coupled to or formed with the handpiece.

17. The dental apparatus of claim 16, wherein the pressure wave generator comprises a filling mode in which the pressure wave generator fills the treatment region and a cleaning mode in which the pressure wave generator cleans the treatment region.

18. The dental apparatus of claim 17, wherein the handpiece comprises a switch to switch between the filling mode and the cleaning mode.

19. The dental apparatus of claim 16, further comprising a console in fluid communication with the handpiece, the console configured to control the operation of a treatment procedure.

20. The dental apparatus of claim 19, wherein the one or more reservoirs is disposed in or on the console.

21. The dental apparatus of claim 1, wherein one of the first and second compositions comprises water.

22. The dental apparatus of claim 1, further comprising the first composition.

23. The dental apparatus of claim 1, wherein the pressure wave generator is further configured to deliver cleaning fluid through an opening and to generate pressure waves through the treatment region to cause the cleaning fluid to substantially clean the treatment region.

24. The dental apparatus of claim 1, further comprising a cartridge configured to couple with the handpiece, wherein the cartridge comprises the first supply line and the second supply line, the cartridge comprising a switch to switch between the first and second supply lines.

25. The dental apparatus of claim 1, wherein the apparatus is configured to operate in a cleaning mode in which cleaning fluid passes through an opening to clean the treatment region, and

wherein the apparatus is configured to operate in a filling mode in which the filling material passes through the opening to fill the treatment region.

26. The dental apparatus of claim 1, wherein the pressure wave generator comprises an opening to deliver at least one of the first composition, the second composition, and the filling material to the treatment region.

27. The dental apparatus of claim 1, wherein the pressure wave generator is further configured to substantially clean the treatment region.
