Clinical Studies Highlight Initial Hydrophilicity of
Impregum™ Polyether Impression Materials from 3M ESPE
Superior performance during unset stage; entire working time
 
ST. PAUL, Minn. – (August 7, 2007) – Data is mounting in favor of the initial hydrophilic properties of 3M ESPE Impregum polyether impression materials, according to recent comparative studies  released by 3M ESPE. The clinical data reveals a significant difference in the hydrophilic behavior of polyether and VPS impression materials, especially in the clinically relevant unset stage of the working process. Even in the presence of moisture or saliva, the hydrophilic nature of Impregum polyether impression materials ensures that the impression is unaffected and maintains its precision. 
The studies were designed with an important difference from previous experiments: While existing data suggests many VPS impression materials show an adequate degree of hydrophilicity, past studies were conducted using set impression materials. Because the precision of an impression material depends on its wetting behavior before and during setting, the new experiments examined both polyether and VPS impression materials during the clinically relevant unset stage and throughout the complete setting process.  Through observing contact angles of water drops on polyether and VPS impression materials, results demonstrate the lower contact angles and, thus, hydrophilicity of Impgreum polyether impression materials.
“Clinical studies continue to confirm the superior hydrophilicity and precision of Impregum polyether impression materials,” says Sean Regan, market development supervisor, 3M ESPE. “That clinically reliable performance enables dental professionals around the world to create high quality, reliable impressions, giving them confidence that an accurate impression is captured.”
