Universal alignment indicator
First Claim
1. An improved precise orientating tooth drilling device of a type having drill orientation means for attaching to a dental drill with a drill bit by a drill clamp and generating a drill angular position signal having a drill signal X-component and a drill signal Y-component and representing an angular position of the drill orientation means, tooth orientation means for removably attaching to a tooth and generating a tooth angular position signal having a tooth signal X-component and a tooth signal Y-component and representing an angular position of the tooth, comparing means comparing said drill angular position signal and said tooth angular position signal to each other and determining if a difference therebetween is within a predetermined value, and alarm means alerting when said difference between said drill angular position signal and said tooth angular position signal is not within said predetermined value so that repositioning of the drill can be initiated, said improvement comprising:
- a) said drill angular position signal of said drill orientation means having a drill signal Z-component; and
b) said tooth angular position signal of said tooth orientation means having a tooth signal Z-component.

Abstract
An improved precise orientating tooth drilling device of a type having drill orientation apparatus attaching to a dental drill with a drill bit by a drill clamp and generating a drill angular position signal having a drill signal X-component and a drill signal Y-component and representing an angular position of the drill orientation apparatus, tooth orientation apparatus for removably attaching to a tooth and generating a tooth angular position signal having a tooth signal X-component and a tooth signal Y-component and representing an angular position of the tooth, comparing apparatus for, comparing the drill angular position signal and the tooth angular position signal to each other and determining if a difference therebetween is within a predetermined value, and an alarm alerting when the difference between the drill angular position signal and the tooth angular position signal is not within the predetermined value so that repositioning of the drill can be initiated. The improvement includes the drill angular position signal having a drill signal Z-component and the tooth angular position signal having a tooth signal Z-component.
