Impregum™ Penta™ Polyether Impression Materials – established for many years and repeatedly awarded by many independent rating institutes – have practically become a synonym for top-notch impression precision. With their unique product characteristics, Impregum materials help dentists to achieve excellent impression results.
Top-of-the-class detail reproduction due to outstanding hydrophilicity
Excellent detail reproduction due to outstanding initial hydrophilicity.
Impregum's outstanding initial hydrophilicity displaces moisture right from the first contact with tissue ensuring uncompromised marginal accuracy and integrity. From the time it is mixed until it sets, moisture in the mouth does not interfere with achieving accurate, void-free impressions.
This results in great detail reproduction in a wet environment, which is why most dentists prefer Impregum™ over Vinyl Polysiloxane.
Captures fine details due to excellent flow properties
The Shark Fin Test* proves it: Impregum™ Penta™ Soft (Quick) Polyether Material flows smoothly into the toughest spots, yet does not slump – capturing fine detail and delivering highly accurate precision impressions. In fact, it offers the best flow behaviour throughout the entire working time.
Its snap-set behaviour ensures that it will not start setting before the working time ends; when it does, though, it does so immediately. Hence, the indicated working time can actually be used to full capacity.
Different formulas, the same precision:
Impregum™ Penta™ Soft Polyether Impression Materials have been developed especially for the monophase technique but additional materials are also available for the heavy body/light body technique.
Impregum™ Penta™ Soft > Easy removal from the mouth and fresh minty flavour
Impregum™ Penta™ Soft Quick > Especially designed for crowns and smaller bridges
Impregum™ Penta™ > Original high-precision polyether for automatic mixing
1-step tray/ wash technique

This investigation evaluated and compared the dimensional accuracy and surface detail reproduction of two VPS (Aquasil Monophase, Dentsply and Genie™ Ultra Hydrophilic, Sultan Chemists Inc.) and two 3M ESPE polyether impression materials (Impregum™ Penta™ Soft and Permadyne™ Garant™ 2:1).
Results: Although moisture may not adversely affect the dimensional accuracy of either polyether or hydrophilic VPS material, the evidence suggests that polyether material is more likely to produce impressions with superior detail reproduction in the presence of moisture.

Aim of the study: The study investigates the hydrophilic and flow behaviour of impression materials.
Results: Impregum™ Polyether Impression Material (3M ESPE) is most hydrophilic and most flowable compared to the VPS materials investigated. An extensive clinical case with 8 single-unit Lava™ Crowns illustrates the high clinical relevance of Impregum’s excellent flow properties and hydrophilicity. The precision impression with Impregum™ Penta™ Soft Quick Material has earned the appreciation of the dental technician for its detailed accuracy.
