Method and device for causing tooth movement
A method of increasing movement of a tooth in a jaw having at least one tooth with an orthodontic brace thereon includes: (1) holding a handle of a device, the device having an elongate member extending from the handle and a screw tip at a distal end of the elongate member; (2) moving a sleeve along the elongate member to set a length of exposed screw tip; (3) locking the sleeve in place relative to the screw tip; (4) drilling a hole with the screw tip through a cortical bone of a jaw to increase movement of the tooth; and (5) stopping the drilling when the length of exposed screw tip has penetrated the jaw.
1. A method of increasing movement of a tooth in a jaw by provoking an inflammatory response, the method comprising:
(a) holding a handle of a device, the device having an elongate member extending from the handle and a screw tip at a distal end of the elongate member;
(b) contacting the screw tip of the device with gingival tissue at a predetermined site on the gingival tissue;
(c) screwing the screw tip of the device by applying a pressure force on the screw tip towards the gingival tissue along a first axis while simultaneously applying a rotational force on the screw tip in a first direction causing the screw tip to enter the gingival tissue at the predetermined site and to enter cortical bone tissue underneath the predetermined site on the gingival tissue;
(d) displacing cortical bone tissue radial to the first axis as a result of said screwing step;
(e) stopping the screwing of the screw tip into the gingival tissue when the screw tip has reached a desired depth in the cortical bone tissue; and
(f) removing the screw tip from the gingival tissue and the cortical bone tissue by applying a rotational force on the screw tip in a second direction opposite the first direction;
wherein said displacing step does not cause removal of cortical bone tissue.
2. The method of claim 1 , wherein the inflammatory response comprises an increased presence of cytokines near a tooth to be moved.
3. The method of claim 2 , wherein the increased presence of cytokines promotes formation and activation of osteoclasts, which cause an increase in bone remodeling and movement.
4. The method of claim 1 , further comprising repeating steps a)-f) a plurality of times at a different predetermined site each time.
5. The method of claim 1 , wherein the predetermined site is proximal to a central or lateral tooth or in a palatal.
6. The method of claim 5 , wherein the screw tip is about 3 mm in length.
7. The method of claim 1 , predetermined site is near a malocclusion to be treated.
8. The method of claim 1 , wherein the desired depth is less than 10 mm.
9. The method of claim 8 , wherein the desired depth is about 3 mm, 5 mm, or 7 mm.
10. The method of claim 1 , wherein the predetermined site is proximal to a posterior molar or in a mandible.
11. The method of claim 10 , wherein the screw tip is about 7 mm in length.
12. The method of claim 1 , wherein the screw tip is about 3 mm to 7 mm in length.
13. The method of claim 1 , further comprising exerting a continuous force on the tooth to be moved.
14. The method of claim 13 , wherein the exerting a continuous force is performed through the use of braces.
15. The method of claim 1 , wherein contacting the screw tip of the device with gingival tissue at the predetermined site is performed at an about 90-degree angle.
16. A method of increasing movement of a tooth in a jaw by provoking an inflammatory response, the method comprising:
(a) holding a handle of a device, the device having an elongate member extending from the handle, a screw tip at a distal end of the elongate member, and a sleeve configured to move along the elongate member to vary the length of exposed screw tip;
(b) contacting the screw tip of the device with gingival tissue at a predetermined site on the gingival tissue;
(c) screwing the screw tip of the device by applying a pressure force on the screw tip towards the gingival tissue along a first axis while simultaneously applying a rotational force on the screw tip in a first direction causing the screw tip to enter the gingival tissue at a predetermined site and to enter cortical bone tissue underneath the predetermined site on the gingival tissue;
(d) displacing cortical bone tissue radial to the first axis as a result of said screwing step;
(e) stopping the screwing of the screw tip when the sleeve makes contact with the gingival tissue; and
(f) removing the screw tip from the gingival tissue and the cortical bone tissue by applying a rotational force on the screw tip in a second direction opposite to the first direction;
wherein said displacing step does not cause removal of cortical bone tissue.
17. The method of claim 16 , wherein the sleeve is adjusted to a position along the elongated member thereby causing the length of exposed screw tip to be fixed.
18. The method of claim 17 , wherein the length of exposed screw tip is about 3 mm, 5 mm or 7 mm.
19. The method of claim 16 , wherein contacting the screw tip of the device with gingival tissue at the predetermined site is performed at an about 90-degree angle.
