Paragraph Number

12

In one aspect, the gap gauge may include a balance gauge coupled to the balance indicator. The balance gauge may include a dial having marks positioned on a face to indicate a measure of the orientation of the superior plate relative to the inferior plate. The balance gauge may also include a needle connected to the balance indicator such that rotation of one of the superior plate and the inferior plate about an anterior-posterior axis of the patient moves the needle to point toward a mark on the face of the dial that reflects the orientation.
