## Abstract

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.

## Claims

### Claim 1

A method of increasing movement of a tooth in a jaw, the method comprising:
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;
moving a sleeve along the elongate member to set a length of exposed screw tip;
locking the sleeve in place relative to the screw tip;
drilling a hole with the screw tip through a cortical bone of a jaw, wherein the jaw comprises at least one tooth having an orthodontic brace thereon, the drilling performed to increase movement of the tooth; and
stopping the drilling when the length of exposed screw tip has penetrated the jaw.

### Claim 2 (depends on 1)

The method of claim 1, wherein drilling a hole comprises drilling a hole in a mesial surface of the jaw.

### Claim 3 (depends on 2)

The method of claim 2, further comprising drilling a plurality of holes spaced along a mesial surface of the jaw.

### Claim 4 (depends on 1)

The method of claim 1, wherein drilling a hole comprises drilling a hole in a gingival flap.

### Claim 5 (depends on 1)

The method of claim 1, wherein drilling a hole comprising drilling the hole proximal to a central or lateral tooth or drilling a hole in the palatal.

### Claim 6 (depends on 5)

The method of claim 5, wherein the length of exposed screw tip is approximately 3 mm.

### Claim 7 (depends on 1)

The method of claim 1, wherein drilling a hole comprises drilling the hole in a canine or a premolar.

### Claim 8 (depends on 7)

The method of claim 7, wherein the length of exposed screw tip is approximately 5 mm.

### Claim 9 (depends on 1)

The method of claim 1, wherein drilling a hole comprises drilling the hole proximal to posterior molars or in the mandible.

### Claim 10 (depends on 9)

The method of claim 9, wherein the length of exposed screw tip is approximately 7 mm.
