Abstract

A method and instrument for performing periodontal surgery to correct a gingival defect of a patient comprises the steps of making an incision at or near a fornix of the patient near the gingival defect, inserting an instrument into the incision to detach a flap, advancing the flap horizontally without enlarging the incision, elevating a papilla within the flap, stretching the flap to cover the gingival defect, and pressing against the flap to promote fibrin formation An instrument comprises a handle, a first shank extending from the handle a connector section and a blade section The connector section further comprises a first end and a second end, wherein the first end connects to the first shank at a first angle, and the second end connects to the blade section at a second angle The blade section is approximately perpendicular to a plane formed by the handle and the connector section.

Claims

1. An instrument for performing periodontal surgery, comprising:
a handle;
a connector section comprising a first end and a second end, the first end connecting to the handle; and, a blade section connecting to the second end of the connector section;
wherein, the handle and the first end of the connector section forms a first angle;
the second end of the connector section and the blade section forms a second angle; and, the blade section comprises a cutting surface, said cutting surface lies on a plane substantially parallel to the second end of the connector section.

2. The instrument of claim 1, wherein length directions of the handle and the connector section forms a plane, and a length direction of the blade section is substantially perpendicular to said plane.

3. The instrument of claim 1, wherein each of the first angle and the second angle is between 80-100 degrees, and the connector section comprises a straight shank.

4. The instrument of claim 3, wherein the first angle is approximately 90 degrees in the counter-clockwise direction, and the second angle is approximately 90 degrees in the clockwise direction.

5. The instrument of claim 3, wherein the first angle is approximately 90 degrees in the clockwise direction, and the second angle is approximately 90 degrees in the counter-clockwise direction.

6. The instrument of claim 1, wherein the blade section is one of either a half-moon shape or a spear shape.

7. The instrument of claim 1, further comprising a first shank extending linearly from the handle, wherein the connector section connects to the handle through the first shank.

8. The instrument of claim 1, wherein the blade section is 1-3 mm wide and comprises a sharp point with cutting edges on two sides.

9. The instrument of claim 1, wherein the blade section is thin and needle-like.

10. The instrument of claim 1, wherein the blade section further comprises a tip that curves 10-30 degrees.

11. The instrument of claim 1, wherein the blade section is composed of one of surgical-grade stainless steel, titanium, and titanium-nitride (TiN).

12. The instrument of claim 11, wherein the blade section further comprises a protectant coating.

13. The instrument of claim 12, wherein the protecting coating is Titanium Nitrite (TiN).

14. The instrument of claim 3, wherein the connector section is approximately 11 mm long, and the blade section is approximately 13 mm long.

15. The instrument of claim 3, wherein, the connector section is within a range of 4-18 mm long, and the blade section is within a range of 4-21 mm long.

16. The instrument of claim 1, wherein the connector section further comprises:
a second shank comprising the first end of the connector section connected to the first shank at the first angle;
a third shank comprising the second end of the connector section connected to the blade section at the second angle; and, wherein the second shank and the third shank adjoins and forms a third angle.

17. The instrument of claim 16, wherein the first angle is approximately 60 degrees, the second angle is approximately 90 degrees, and the third angle is approximately 60 degrees.

18. The instrument of claim 16, wherein the first angle is approximately 100 degrees, the second angle is approximately 90 degrees, and the third angle is approximately 110 degrees.

19. The instrument of claim 16, wherein the first angle is 10-90 degrees, the second angle is approximately 90 degrees, and the third angle is 10-90 degrees.

20. The instrument of claim 16, wherein the first angle is 90-135 degrees, the second angle is approximately 90 degrees, and the third angle is 90-135 degrees.

21. The instrument of claim 16, wherein the second shank is approximately 11 mm long, and the third shank is approximately 8 mm long.

22. The instrument of claim 16, wherein the second shank is approximately 6 mm long, and the third shank is approximately 11 mm long.

23. The instrument of claim 16, wherein each of the second shank and the third shank is within a range or 4-18 mm long.

24. The instrument of claim 1, wherein the handle and connector section are integrally formed of a same material.

25. The instruments of claim 24, wherein the handle, connector section, and blade section are integrally formed of the same material.

26. An instrument for performing periodontal surgery, comprising:
a handle;

a first shank connecting to and extending linearly from the handle;
a second shank connecting to the first shank at a first angle;
a third shank connecting to the second shank at a second angle;
a blade section connecting to the third shank at a third angle;
wherein, the first angle is between 90 to 135 degrees, the second angle is between 90 to 135 degrees, the third angle is approximately 90 degrees, the blade section is approximately orthogonal to a plane defined by length directions of the first shank, second shank, and third shank, and, the blade section comprises a cutting surface, said cutting surface lies on a plane substantially parallel to a length direction of the third shank.

27. A method of performing periodontal surgery to correct a gingival defect on a patient, comprising the steps of:

making an incision at or near a fornix of the patient near the gingival defect, inserting an instrument into the incision to detach a flap, extending the flap horizontally without enlarging the incision, elevating a papilla within the flap, advancing the flap to cover the gingival defect, and, pressing against the flap to promote fibrin formation.

28. The method of performing periodontal surgery to correct a gingival defect according to claim 27, wherein the incision is between 3-5 mm in length.

29. The method of performing periodontal surgery to correct a gingival defect according to claim 27, wherein the incision is longer than 5 mm in length.

30. The method of performing periodontal surgery to correct a gingival defect according to claim 27, wherein no suturing is performed.

31. The method of performing periodontal surgery to correct a gingival defect according to claim 27, wherein the step of extending the flap horizontally further comprises extending the flap to cover a tooth immediately distal to the incision or a tooth immediately mesial to the incision.

32. The method of performing periodontal surgery to correct a gingival defect according to claim 27, further comprising the steps of:
determining whether the flap is stable, and, performing papillary augmentation upon a determination that the flap is unstable.
