Abstract

Dimensional accuracy when making impressions is crucial to the quality of fixed prosthodontic treatment, and the impression technique is a critical factor affecting this accuracy. The purpose of this study was to compare the dimensional accuracy of one-step putty wash and two-step putty wash impression techniques using commercially available addition silicone impression material. The accuracy was assessed  by measuring intraabutment and interabutment dimensions on stone dies poured from impressions of the master model, by using Toolmaker’s microscope.

Keywords: Addition silicone impression material, Toolmaker’s microscope, Polyvinyl siloxane, Universal testing machine (UTM).
