Abstract

Claims (45)

1. A surgical method comprising the steps of:

inserting a first screw through a first hole extending through a first plate and into a mandible;

inserting a second screw through a second hole extending through the first plate and into the mandible;

inserting a third screw through a third hole extending through a second plate and into a maxilla;

inserting a fourth screw through a fourth hole extending through the second plate and into the maxilla; and

attaching a first wire to the first plate and the second plate, the first wire preventing movement of the mandible away from the maxilla.

2. The surgical method of claim 1 , further comprising the steps of bending the first plate to the contour of the mandible and bending the second plate to the contour of the maxilla.

3. The surgical method of claim 1 , wherein the attaching step includes attaching the first wire to a first hook monolithically formed with the first plate and a second hook monolithically formed with second plate.

4. The surgical method of claim 3 , further comprising the step of attaching a second wire to a third hook monolithically formed with the first plate and a fourth hook monolithically formed with the second plate.

5. The surgical method of claim 4 , wherein the first and second wires cross each other.

6. The surgical method of claim 1 , further comprising the step of bending a first stem connecting the first hole to the first plate.

7. The surgical method of claim 6 , further comprising the step of bending a second stem connecting the second hole to the first plate.

8. A surgical method comprising the steps of:

determining a placement of a first plate on a mandible;

placing the first plate adjacent the mandible;

determining a first position in the mandible for a first screw to pass through the first plate into the first position in the mandible;

determining a second position in the mandible for a second screw to pass through the first plate into the second position in the mandible;

inserting the first screw through the first plate and into the mandible at the first position;

inserting the second screw through the first plate and into the mandible at the second position;

determining a placement of a second plate on a maxilla;

placing the second plate adjacent the maxilla;

determining a third position in the maxilla for a third screw to pass through the second plate into the third position in the maxilla;

determining a fourth position in the maxilla for a fourth screw to pass through the second plate into the fourth position in the maxilla;

inserting the third screw through the second plate and into the maxilla at the third position;

inserting the fourth screw through the second plate and into the maxilla at the fourth position;

determining a first connection point for a first wire to engage the first plate and a second connection point for the first wire to engage the second plate; and

attaching the first wire to the first and second plates.

9. The surgical method of claim 8 , further comprising the steps of determining a contour of the first plate to match the contour of the mandible and determining a contour of the second plate to match the contour of the maxilla.

10. The surgical method of claim 8 , wherein the first connection point is a first hook monolithically formed with the first plate and the second connection point is a second hook monolithically formed with the second plate.

11. The surgical method of claim 9 , further comprising the steps of bending the first plate to the contour of the mandible and bending the second plate to the contour of the maxilla.

12. The surgical method of claim 9 , further comprising the step of attaching a second wire to the first and second plates and crossing the first and second wires.

13. A method comprising the steps of:

bending a first plate to the contour of a mandible;

inserting a first screw through the first plate and into the mandible;

inserting a second screw through the first plate and into the mandible;

bending a second plate to the contour of a maxilla;

inserting a third screw through the second plate and into the maxilla;

inserting a fourth screw through the second plate and into the maxilla; and

attaching a first wire to a first hook of the first plate and a second hook of the second plate, the first wire preventing movement of the mandible away from the maxilla.

14. The method of claim 13 , further comprising the step of attaching a second wire to a third hook of the first plate and a fourth hook of the second plate.

15. The method of claim 14 , wherein the first and third hooks are monolithically formed with the first plate and the second and fourth hooks are monolithically formed with the second plate.

16. The method of claim 14 , wherein the first and second wires cross each other.

17. The method of claim 13 , wherein the first screw is inserted through a first hole in the first plate, the second screw is inserted through a second hole in the first plate, the third screw is inserted through a third hole in the second plate, and the fourth screw is inserted through a fourth hole in the second plate.

18. The method of claim 13 , further comprising the steps of bending at least one of a first stem connecting the first hole to the first plate, a second stem connecting the second hole to the first plate, a third stem connecting the third hole to the second plate and a fourth stem connecting the fourth hole to the second plate.

19. The method of claim 18 , further comprising the step of bending each of the first, second, third and fourth stems.
