Abstract

The aim of this study was to evaluate the changes in the dentist’s stress caused by taking an impression, using either the optical impression technique based on digital technology or two different conventional impression techniques. The study was performed following the principles outlined in the Declaration of Helsinki on experimentation involving human subjects, and the protocol was reviewed and approved by the Ethics Committee. Three different impression techniques were used in this study.

1: Agar-alginate combined impression technique (Hydrocolloid impression).

2: Silicone single impression technique (Silicone impression).

3: Optical impression technique (optical impression).

Based on these results, it can be concluded that optical impression is a lower stress technique for the operator, and more time efficient.
