Method and device for causing tooth movement

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.
