Abstract

A method produces a base for physical tooth models. The method includes providing one or more cast materials in a container, pressing the underside of the physical tooth models into the one or more cast materials to produce impressions in the one or more cast materials, and solidifying the one or more cast materials having the impressions to produce the base that is adapted to receive the physical tooth models.

Claims (52)

1. A method for producing a base to receive physical models of one or more teeth, comprising:

providing a cast material in a container;

impressing undersides of a plurality of individual physical tooth models into the cast material to produce impressions of the undersides in the cast material, said plurality of individual physical tooth models comprising a portion of a dental arch, wherein individual physical tooth models of said plurality of individual physical tooth models having been obtained in such a manner that said individual physical tooth models may be joined with each other to form said portion of said dental arch;

solidifying the cast material with the impressions to produce a base configured to receive the plurality of individual physical tooth models; and

labeling the plurality of individual physical tooth models in a predetermined sequence.

2. The method of claim 1 , wherein the cast material consists of one or more of a polymer, a thermal elastic material, a urethane, an epoxy, a plaster, a clay, an acrylic, a latex, a dental PVS, a resin, a metal, an aluminum material, an ice material, and a wax material.

3. The method of claim 1 further comprising:

defining the positions of the impressions on the base in accordance with a patient's arch.

4. The method of claim 1 , comprising heating or cooling the cast materials to cause the solidification of the cast materials having the impressions.

5. The method of claim 1 , wherein solidifying the cast material comprises applying at least one of microwave radiation, ultraviolet radiation and infrared radiation.

6. The method of claim 1 , further comprising applying one or more crosslinking agents to the cast materials to cause polymerization and solidification of the cast materials having the impressions.

7. The method of claim 1 , wherein the plurality of individual physical tooth models comprise first features to assist the reception of the plurality of individual physical tooth models by the base.

8. The method of claim 7 , wherein the features consists of one or more of a pin, a registration slot, a notch, a protrusion, a hole, an interlocking mechanism, a jig, and a pluggable or attachable feature.

9. The method of claim 7 , wherein the impressions in the base comprise second features complementary to the first features to assist the reception of the plurality of individual physical tooth models by the base.

10. The method of claim 1 , further comprising:

placing the plurality of individual physical tooth models in a container;

wherein impressing the undersides of the plurality of individual physical tooth models into the cast material comprises pouring the cast material over the underside of the plurality of individual physical tooth models in the container.

11. The method of claim 1 , further comprising assembling the base with one or more additional bases to form a dental arch model.

12. The method of claim 1 , wherein the predetermined sequence defines the positions of the plurality of individual physical tooth models on the base.

13. A method for producing a base to receive physical models of one or more teeth, comprising:

providing a cast material in a container;

impressing undersides of a plurality of individual physical tooth models into the cast material to produce impressions of the undersides in the cast material, said plurality of individual physical tooth models comprising a portion of a dental arch, wherein individual physical tooth models of said plurality of individual physical tooth models having been obtained in such a manner that said individual physical tooth models may be joined with each other to form said portion of said dental arch; and

solidifying the cast material with the impressions to produce a base configured to receive the plurality of individual physical tooth models, said solidifying comprising applying radiation.

14. The method of claim 13 , wherein the cast material consists of one or more of a polymer, a thermal elastic material, a urethane, an epoxy, a plaster, a clay, an acrylic, a latex, a dental PVS, a resin, a metal, an aluminum material, an ice material, and a wax material.

15. The method of claim 13 , comprising:

labeling the plurality of individual physical tooth models in a predetermined sequence that defines the positions of the plurality of individual physical tooth models on the base.

16. The method of claim 13 further comprising:

defining the positions of the impressions on the base in accordance with a patient's arch.

17. The method of claim 13 , wherein the plurality of individual physical tooth models comprise first features to assist the reception of the plurality of individual physical tooth models by the base.

18. The method of claim 17 , wherein the features consists of one or more of a pin, a registration slot, a notch, a protrusion, a hole, an interlocking mechanism, a jig, and a pluggable or attachable feature.

19. The method of claim 17 , wherein the impressions in the base comprise second features complementary to the first features to assist the reception of the plurality of individual physical tooth models by the base.

20. The method of claim 13 , further comprising:

placing the plurality of individual physical tooth models in a container;

wherein impressing the undersides of the plurality of individual physical tooth models into the cast material comprises pouring the cast material over the underside of the plurality of individual physical tooth models in the container.

21. The method of claim 13 , further comprising assembling the base with one or more additional bases to form a dental arch model.

22. The method of claim 13 , wherein the radiation comprises microwave radiation.

23. The method of claim 13 , wherein the radiation comprises ultraviolet radiation.

24. The method of claim 13 , wherein the radiation comprises infrared radiation.

25. A method for producing a base to receive physical models of one or more teeth, comprising:

providing a cast material in a container;

impressing undersides of a plurality of individual physical tooth models into the cast material to produce impressions of the undersides in the cast material, said plurality of individual physical tooth models comprising a portion of a dental arch, wherein individual physical tooth models of said plurality of individual physical tooth models having been obtained in such a manner that said individual physical tooth models may be joined with each other to form said portion of said dental arch; and

solidifying the cast material with the impressions to produce a base configured to receive the plurality of individual physical tooth models, said solidifying comprising applying one or more crosslinking agents to the cast material to cause polymerization.

26. The method of claim 25 , wherein the cast material consists of one or more of a polymer, a thermal elastic material, a urethane, an epoxy, a plaster, a clay, an acrylic, a latex, a dental PVS, a resin, a metal, an aluminum material, an ice material, and a wax material.

27. The method of claim 25 further comprising:

defining the positions of the impressions on the base in accordance with a patient's arch.

28. The method of claim 25 , wherein the plurality of individual physical tooth models comprise first features to assist the reception of the plurality of individual physical tooth models by the base.

29. The method of claim 28 , wherein the features consists of one or more of a pin, a registration slot, a notch, a protrusion, a hole, an interlocking mechanism, a jig, and a pluggable or attachable feature.

30. The method of claim 28 , wherein the impressions in the base comprise second features complementary to the first features to assist the reception of the plurality of individual physical tooth models by the base.

31. The method of claim 25 , further comprising:

placing the plurality of individual physical tooth models in a container;

wherein impressing the undersides of the plurality of individual physical tooth models into the cast material comprises pouring the cast material over the underside of the plurality of individual physical tooth models in the container.

32. The method of claim 25 , further comprising assembling the base with one or more additional bases to form a dental arch model.
