Abstract

Background:  One of the most challenging aspects of crown and bridge is the management of the gingival tissues when making an impression. With the advent of new materials (like expasyl, magic foam, racegel homeostatic agents) retraction of gingival tissue has become much more comfortable. However, the efficiency of these new materials in gingival displacement is less explored. Hence this study was aimed at evaluating the amount of gingival displacement done by these materials and comparison among these materials.  Materials & Methods: Three below-mentioned retraction system were selected for the study. Retraction cord (ultra-pack)) Magic foam (Colten) Racegel along with retraction cord (Septodent). Materials were manipulated according to manufacturer instructions and injected into selected, prepared anterior teeth. Impressions were made, and obtained models were evaluated under the electron microscope. Appropriate biostatic tests were applied for the analysis of data.  Results: The result of the study conclusions were drawn that all the three-retraction system used showed a highly significant amount of gingival displacement when compared with their pre-displacement state.  Conclusion: Knitted retraction cord impregnated with Racegel haemostatic agent showed maximum displacement and Magic Foam Cord showed the least amount of gingival displacement.
