General Comments – Impression materials are used to make replicas (models or casts) of t eeth and other oral tissues. the reason for this is cost. preparation, and heavy-body material is used in the tray. 1 Tube Base 100 Gm., 1 Tube Catalyst 130 Gm. Your email address will not be published. 5% coupon applied at checkout Save 5% with coupon. With elastomeric impression materials such as polyvinyl siloxane, polyether, and polysulfide, the dimensional accuracy is usually time dependent, with greater dimensional accuracy occurring immediately after polymerization is complete but declining as the impression is stored for extended periods of time. Notify me of follow-up comments by email. – Polysulfide impression materials have a disagreeable smell and taste. Which material is not presently popular and has been replaced by newer products. Polyether impression material is an elastic-type material, as are the polysulfideand silicone materials. curing shrinkage – 0.45% due to continued reaction.
