ABSTRACT:
A dental shade guide has a tooth-shaped first portion and an elongated second portion which is integrally connected to the first portion. The second portion varies in thickness in stepped fashion along its length. Both portions are made of a material having substantially the same color, thereby enabling the user to compare the color of the shade guide in differing degrees of opacity with the color of tooth structure adjacent the intended restoration, in order to increase the likelihood that the finished restoration will appear as aesthetic as possible.
