Abstract

A device and method for applying dental composite matter to dental surfaces, such as cavities in teeth, gaps in teeth, or other deformations in tooth surfaces, or other applications to teeth, or appliances and devices used with teeth, such as crowns or inlays/onlays. A hand held powered tool provides oscillation of the composite material after the composite material is grossly applied to the dental surface. The oscillation is at a frequency and amplitude that facilitates uniform spreading of the composite material over the dental surface in a desired pattern, while retarding the tendency of the material to stick to the tool.

Claims

1. A method of applying a dental composite, comprising the steps of:

a) placing a quantity of dental composite on a dental surface;

b) contacting said dental composite with an oscillating member, wherein a hand held powered tool comprises said oscillating member; and

c) manipulating said dental composite by said oscillating member until said composite is distributed on said dental surface to a desired geometry, wherein said oscillating member oscillates at a frequency of 50 to 200 cycles per second, and wherein said oscillating member oscillates at an amplitude of 0.2 millimeters to 2 milllimeters.

2. The method of applying dental composite as described in claim 1, wherein said method further comprises manipulating said dental composite by said oscillating member until said dental composite is formed to a veneer on said dental surface with said veneer having a smooth and glossy top surface that covers at least a portion of said dental surface.

3. The method of applying dental composite as described in claim 1, wherein said dental surface is a cavity in a tooth, and said dental composite is manipulated by said oscillating member until an outer surface of said dental composite is formed to a desired shape.

4. The method of applying dental composite as described in claim 1, wherein said dental surface comprises a deformation in a tooth, and said dental composite is manipulated by said oscillating member until said deformation is said tooth is substantially filled with said dental composite and said composite material is a sealant for said deformation.

5. The method of applying dental composite as described in claim 1, wherein said dental surface is a site for forming an orthodontic post, and said oscillating member has a void therein having a dimension of a desired dimension of an orthodontic post, and said dental composite is manipulated by said oscillating member until said orthodontic post is formed at said site.

6. The method of applying dental composite as described in claim 1, wherein said dental surface is a natural tooth.

7. The method of applying dental composite as described in claim 1, wherein said dental surface is a laboratory constructed entity.

8. The method of applying dental composite as described in claim 1, wherein said dental surface is a site for luting a dental appliance to said dental surface, and said dental composite is a luting material, and said luting material is manipulated by said oscillating member over at least a portion of said dental surface, and said dental appliance is subsequently placed over said dental surface and said dental appliance is luted to said dental surface.

9. The method of applying dental composite as described in claim 8, wherein said dental appliance is a laboratory constructed appliance.

10. The method of applying dental composite as described in claim 1, wherein said oscillating member comprises a foam member, wherein said foam member is oscillated by said oscillating member, and said foam member contacts and manipulates said dental composite, and wherein said foam member does not materially adhere to said dental composite when said foam member oscillates.

11. The method of applying dental composite as described in claim 7, wherein said foam member comprises closed cell foam.

12. A method of applying dental composite as described in claim 7, wherein said oscillating member comprises an elastomer.

13. A method of applying dental composite as described in claim 1, wherein said dental composite is a filled dental composite.

14. An apparatus for manipulating dental composite, comprising:

a hand held powered tool, said hand held tool comprising an oscillating member, wherein said oscillating member comprises a foam member on an oscillating outer surface of said oscillating member, and wherein said foam member does not materially adhere to an uncured dental composite when said foam member contacts said uncured dental composite when said oscillating member is oscillating, wherein said oscillating member oscillates at a frequency of 50 to 200 cycles per second, and wherein said oscillating member oscillates at an amplitude of 0.2 millimeters to 2.0 millimeters.

15. An apparatus for manipulating dental composite materials as described in claim 14, wherein said foam member comprises closed cell foam.

16. An apparatus for manipulating dental composite materials as described in claim 14, wherein said foam member comprises elastomer.

17. An apparatus for manipulating dental composite materials as described in claim 14, wherein said foam member comprises a flat outer surface.

18. An apparatus for manipulating dental composite materials as described in claim 14, wherein said apparatus comprises a shaft that connects said foam member to said oscillating member.

19. An apparatus for manipulating dental composite materials as described in claim 14, wherein said apparatus comprises a deformable shaft that connects said foam member to said oscillating member, and wherein said deformable shaft deforms by oscillation of said oscillating member and increases an amplitude of said oscillating member at a point of contact of said foam member with a dental composite material to be manipulated.

20. An apparatus for manipulating dental composite materials as described in claim 14, wherein said shaft comprises a fastener that connects said foam member to said oscillating member.
