The success of fixed prosthodontic treatment depends upon precision and accuracy in every step involved in the procedure. A very critical aspect of this is making accurate impressions in terms of dimensional accuracy, tear strength etc. The impression materials at the margins of the preparation require substantial thickness in order to resist distortion. This goal is in terms achieved by adequate gingival retraction. This paper focuses on the evaluation of three different gingival retraction methods namely retraction cord, Magic Foam Cord and Expasyl using width and depth of gingival sulcus as criteria.
