Production of exemplary crowns and fixed partial dentures depends upon the usage of impression materials that accurately reproduces prepared teeth and their relationship to adjacent oral structures. A leading dental manufacturer has introduced an improved elastomeric impression material, but the accuracy of the new material after repeat pours have not been verified.The present study was done to comparatively evaluate dimensional accuracy of vinyl polyether silicone and vinyl polysiloxane elastomeric impression materials after repeated pours at different time intervals.It Was concluded that, because of excellent dimensional stability, both impression materials can be repeatedly poured for two weeks as there is no significant dimensional change overall.
