## Abstract

An apparatus for aligning a dental drill including a guide body having a drill guide through hole including a longitudinal axis, a pair of guide pincer axes orthogonal to and symmetrical about the longitudinal axis and a pair of outer pincer axes orthogonal to and symmetrical about the longitudinal axis, a pair of opposed outer pincers, each outer pincer having an outer engagement protrusion, and each outer pincer is rotatable about a respective one of the pair of outer pincer axes, and a pair of opposed guide pincers, each guide pincer having gear teeth and a guide engagement protrusion, and each guide pincer is rotatable about a respective one of the pair of guide pincer axes. The gear teeth of each guide pincer engage the gear teeth of the other, guide pincer, rotation of one of the pair of guide pincers causes rotation of the other of the pair of guide pincers and the pair of opposed outer pincers rotate independent of each other.

## Claims

### Claim 1

An apparatus for aligning a dental drill comprising:
a guide body comprising a drill guide through hole having a longitudinal axis, a pair of guide pincer axes orthogonal to and symmetrical about the longitudinal axis and a pair of outer pincer axes orthogonal to and symmetrical about the longitudinal axis;
a pair of opposed outer pincers, each outer pincer comprising an outer engagement protrusion, and each outer pincer is rotatable about a respective one of the pair of outer pincer axes; and,
a pair of opposed guide pincers, each guide pincer comprising gear teeth and a guide engagement protrusion, and each guide pincer is rotatable about a respective one of the pair of guide pincer axes,
wherein the gear teeth of each guide pincer engage the gear teeth of the other guide pincer, rotation of one of the pair of guide pincers causes rotation of the other of the pair of guide pincers and the pair of opposed outer pincers rotate independent of each other.

### Claim 2 (depends on 1)

The apparatus of claim 1 further comprising:
a pair of outer pincer springs each comprising a first end and a second end,
wherein the first end of each of the pair of outer pincer springs contacts the guide body and the second end of each of the pair of outer pincer springs contacts a respective one of the pair of outer pincers.

### Claim 3 (depends on 1)

The apparatus of claim 1 further comprising:
a pair of guide pincer springs each comprising a first end and a second end,
wherein the first end of each of the pair of guide pincer springs contacts the guide body and the second end of each of the pair of guide pincer springs contacts a respective one of the pair of guide pincers.

### Claim 4 (depends on 1)

The apparatus of claim 1 further comprising:
a guide pincer spring comprising a first end and a second end,
wherein the first end of the guide pincer spring contacts the guide body and the second end of the guide pincer spring contacts one of the pair of guide pincers.

### Claim 5 (depends on 1)

The apparatus of claim 1 further comprising:
a pair of outer pincer springs each comprising a first end and a second end,
a pair of guide pincer springs each comprising a first end and a second end,
wherein the first end of each of the pair of outer pincer springs contacts the guide body, the second end of each of the pair of outer pincer springs contacts a respective one of the pair of outer pincers, the first end of each of the pair of guide pincer springs contacts the guide body and the second end of each of the pair of guide pincer springs contacts a respective one of the pair of guide pincers.

### Claim 6 (depends on 1)

The apparatus of claim 1 wherein each of the guide engagement protrusions and each of the outer engagement protrusions contacts a patient gum tissue, contacts a patient jawbone or contacts the patient gum tissue and the patient jawbone,

### Claim 7

An apparatus for aligning a dental drill comprising:
a guide body comprising a drill guide through hole having a longitudinal axis, a pair of guide pincer axes orthogonal to and symmetrical about the longitudinal axis and a pair of outer pincer axes orthogonal to and symmetrical about the longitudinal axis;
a pair of opposed outer pincers, each outer pincer comprising an outer engagement protrusion, and each outer pincer is rotatable about a respective one of the pair of outer pincer axes; and,
a pair of opposed guide pincers, each guide pincer comprising a guide engagement protrusion, and each guide pincer is rotatable about a respective one of the pair of guide pincer axes,
wherein the pair of opposed outer pincers rotate independent of each other and the pair of opposed guide pincers rotate independent of each other.

### Claim 8 (depends on 7)

The apparatus of claim 7 further comprising:
a pair of outer pincer springs each comprising a first end and a second end,
wherein the first end of each of the pair of outer pincer springs contacts the guide body and the second end of each of the pair of outer pincer springs contacts a respective one of the pair of outer pincers.

### Claim 9 (depends on 7)

The apparatus of claim 7 further comprising:
a pair of guide pincer springs each comprising a first end and a second end,
wherein the first end of each of the pair of guide pincer springs contacts the guide body and the second end of each of the pair of guide pincer springs contacts a respective one of the pair of guide pincers.

### Claim 10 (depends on 7)

The apparatus of claim 7 further comprising:
a pair of outer pincer springs each comprising a first end and a second end,
a pair of guide pincer springs each comprising a first end and a second end,
