ABSTRACT:
A dental space measuring instrument for insertion in interdental or interproximal spaces between teeth in both the upper and lower dental arches to determine the width of such spaces for orthodontic treatment. The dental space measuring instrument is characterized by a centrally located handle provided with outwardly extending, graduated cylinders which define elongated, calibrated tips for insertion in the interdental spaces. The calibrated tips may be extended in a straight line from the handle or one or more cylinders in one or both of the calibrated tips may be angulated, and the diameter of each cylinder is indicated on the handle for size-identification purposes.
