Claims8
A dental measuring apparatus for measuring existing dentures comprising:
- a substantially C-shaped body including a first arm, a second arm and an intermediate part defining a longitudinal axis;
- a first reference member mounted to said first arm;
- said first reference member projecting in a direction substantially parallel to said longitudinal axis and towards said second arm;
- first ruler means mounted to said second arm;
- said first ruler means being slidable in a direction substantially colinear with said first reference member;
- connecting means mounted to said intermediate part;
- said connecting means being slidable along said longitudinal axis;
- and
- second ruler means mounted to said connecting means;
- said second ruler means being slidable in a direction substantially perpendicular to said longitudinal axis;
- whereby, by placing said existing dentures between said first reference member and said first ruler means, measurements of an existing denture in a direction parallel to said longitudinal axis may be determined from said first ruler means and, by sliding said second ruler means towards said denture, measurements of said existing denture in a direction perpendicular to said longitudinal axis may be determined from said second ruler means.
