ABSTRACT
Background:
Flow characteristics of vinyl polysiloxane (VPS) impression materials are important determinants in the selection of impression materials for the fabrication of accurate indirect restorations.Aims:
The purpose of this study was to determine the flow of three commercially available VPS impression materials at different time intervals using a shark fin device (3M ESPE, Seefeld, Germany). Study Setting andDesign:
This in?vitro study was carried out at the prosthodontics department of a dental institution. Methods andMaterial:
The height of the shark fin produced by each impression material determined the rate of flow. StatisticalAnalysis:
The data were analysed using one?way analysis of variance (ANOVA) and post?hoc Tukey’s test (p?0.05).Results:
Shark fin height of group A VPS impression material was significantly higher at 30 and 120 seconds compared to group B and group C VPS impression materials. Shark fin height produced by group B VPS impression materials at 60 and 90 seconds was significantly higher than the group C VPS impression material but non?significant compared to group A. At 120 seconds, there was no significant difference in the shark fin heights of all the tested materials.Conclusion:
All the materials exhibited adequate flow characteristics within clinically acceptable limits
