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 device for forming holes in the cortical bone adjacent a tooth in order to increase movement of the tooth, the device comprising:
a handle;
an elongate member extending from the handle and separable therefrom;
a screw tip at a distal end of the elongate member, wherein the screw tip is configured to drill into cortical bone to increase movement of the tooth; and
a spring biased sleeve extending over the screw tip, the sleeve configured to rest against tissue during use and move with respect to the elongate member to vary the length of exposed screw tip as force is applied to the handle;
wherein the handle comprises a first end attached to the elongate member and a second end, the first end rotatable with respect to the second end to control rotation of the screw tip; and
wherein the elongate member includes teeth configured to interlock with teeth inside of the handle to hold the handle axially in place relative to the elongate member.
2. The device of claim 1 , wherein a length of the screw tip is configured to vary from 0 mm to 6 mm depending upon a position of the spring biased sleeve.
3. The device of claim 1 , wherein the spring biased sleeve is configured to slide into the elongate member.
4. The device of claim 1 , wherein the elongate member is separable from the handle through a user-activated mechanism.
5. The device of claim 4 , wherein the user-activated mechanism is on the handle.
6. The device of claim 5 , wherein the user-activated mechanism is a button on the handle.
7. A device for forming holes in the cortical bone adjacent a tooth in order to increase movement of the tooth, the device comprising:
a handle;
an elongate member extending from the handle and separable therefrom, wherein the elongate member includes teeth configured to interlock with teeth inside of the handle to hold the handle axially in place relative to the elongate member;
a screw tip at a distal end of the elongate member, wherein the screw tip is configured to drill into cortical bone to increase movement of the tooth; and
a user-activated control on the handle configured to release the elongate member and the screw tip from the handle when activated.
8. The device of claim 7 , wherein the handle comprises a first end attached to the elongate member and a second end, the first end rotatable with respect to the second end.
9. The device of claim 8 , wherein the first end is configured to control rotation of the screw tip.
10. The device of claim 7 , wherein a length of the screw tip is configured to be between 0 mm and 6 mm.
11. The device of claim 7 , further comprising a spring biased sleeve extending over the screw tip, the sleeve configured to rest against tissue during use and move with respect to the elongate member to vary the length of exposed screw tip as force is applied to the handle.
12. The device of claim 11 , wherein the spring biased sleeve is configured to slide into the elongate member.
13. The device of claim 7 , wherein the user-activated control is a button on the handle.
