To understand why polyether is out and why additional silicone is the most commonly used impression material we need to know the different uses and properties of each elastomeric material. The flowability of polyether impression material allows it to reach deep into the sulcus to capture the fine detail needed for a properly fitted crown and restoration. With better initial hydrophilicity than any VPS, Impregum polyether material enables excellent dental reproduction in a wet environment. These materials have demonstrated good accuracy in clinical evaluations and are thixotropic, which provides good surface detail and makes them useful as a border molding material. fide and polyether (18,21,28).
