Abstract

This invention is directed to a positioning jig for preparing a two or more of adjacent teeth for a dental prosthesis comprising a member with (i) three or more parallel bores in the member and (ii) one or more means to attach the member to a dental articulator. The invention is also directed to methods of use of the position jig such as to prepare a series of aligned holes in teeth or aligned holes mockup of a dental bridge for a prosthesis.

Claims

1. A positioning jig for preparing two or more adjacent teeth for a dental prosthesis comprising:

a member with (i) three or more parallel bores in the member; and

(ii) one or more means for attaching the member to a dental articulator.

2. The positioning jig of claim 1, wherein the member has four or more parallel bores.

3. The positioning jig of claim 1, wherein the member has six or more parallel bores.

4. The positioning jig of claim 1, wherein the parallel bores are perpendicular to the plane of the member.

5. The positioning jig of claim 3, at least three of the parallel bores are of a first diameter and at least three of the parallel bores are of a second diameter.

6. The positioning jig of claim 1, wherein the member has one means for attaching the member to the dental articulator.

7. The positioning jig of claim 1, wherein the means for attaching the member to the dental articulator is a screw.

8. The positioning jig of claim 1, wherein the means for attaching the member to the dental articulator is a pin and a screw.

10. The positioning jig of claim 1, wherein the member is a plastic frame.

11. The positioning jig of claim 10, wherein the plastic frame is a clear plastic frame.

9. (canceled)

12. A method of preparing an artificial prosthesis having two or more adjacent teeth which comprises:

(a) preparing an artificial tooth arrangement (ATA) with two or more adjacent teeth in a mold on a positioning jig comprising a member with (i) three or more parallel bores in the member and (ii) one or more means for attaching the member to a dental articulator;

(b) placing at least three rigid struts in the parallel bores of the positioning jig;

(c) using at least one of the rigid struts to align a drill;

(d) drilling an aligned hole into each of the teeth in the mold;

(e) placing a rod in each of the aligned holes of the teeth to form a series of aligned rods;

(f) using the teeth and the aligned rods to prepare a dental mockup;

(g) copying the dental mockup to prepare a dental bridge; and

(h) affixing the teeth using the aligned holes to the dental bridge so as to prepare the artificial prosthesis.

13. The method of claim 12, wherein the dental bridge is acrylic.

14. The method of claim 12, wherein the dental bridge is metal.

22. The method of claim 12, wherein the artificial tooth arrangement (ATA) is prepared with three or more adjacent teeth.

23. The method of claim 22, wherein the artificial tooth arrangement (ATA) is prepared with a full arch of adjacent teeth.

25. A kit which comprises:

(a) a positioning jig for preparing two or more adjacent teeth for a dental prosthesis comprising a member with (i) three or more parallel bores in the member and (ii) one or more means for attaching the member to a dental articulator; and

(b) three or more rigid struts with a diameter so they fit tightly in the parallel bores.

26. The kit of claim 25, wherein at least three of the parallel bores are of a first diameter and at least three of the parallel bores are of a second diameter;

three or more rigid struts with a diameter so they fit tightly in the parallel bores of the first diameter; and

three or more rigid struts having a diameter so they fit tightly in the parallel bores of the second diameter.

27. The kit of claim 25, further comprising a set of shrink wrap tubes with a diameter suitable to fit on the rigid struts.

28. The kit of claim 25, wherein the rigid struts are made of a ferrous material and further comprising a set of magnets capable of holding the rigid struts in the bores of the positioning jig.

29. The kit of claim 25, further comprising a form for casting a mold to support an artificial tooth arrangement (ATA).

30. The kit of claim 25, further comprising one or more drill bits suitable for drilling holes in artificial teeth.
