Method and device for causing tooth movement

摘要

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.

主权项

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.
