They also set very quickly and the manipulation has to be fast and effective. That is why dentists and dental technician use wax to fill in some deep undercuts. Accuracy and detail reproduction, setting time, hydrophilicity: when you’re making a dental impression, you need it all. These materials are very stiff and come in only one viscosity. Create great impressions for great-fitting restorations. Polyether materials have a good accuracy and tear resistance. Four types of elastomeric impression materials are available for crowns and fixed partial denture impres- sions : addition silicone, condensation silicone. Very acceptable by the patients because of the nice smell. If used properly they are very dimensionally stable. Dentists don’t need any special equipment for these materials. The polyether impressions are the most hydrophilic elastomeric impressions out there. The mixing time is 35 seconds and the setting time is 5 to 6 minutes. The second one is catalyst paste that includes ester derivatives of aromatic sulphonic acid, plasticizer, thinner and methylcellulose. The first one is base and contains pre polymer ethylene amine, plasticizer, inner filler. 148.46 Impregum Penta Super Quick Medium Body, Fast Set. Impregum Penta Material displaces moisture when it really. Polyether Permadyne Light Body (Syringe), Polyether Impression Material, Handmix: 2 - 120 30751. Polyether materials are packed in two pastes. The original polyether precision impression material that is ideal for use in the monophase technique. The most common uses include getting impressions for inlays and onlays, during preparation for crowns and bridges, during the construction of partial and complete dentures, functional impressions, Chemical Ingredients: The most common uses of polyether impression materials are for the construction of partial and total dentures, the preparation for crowns and bridges, and to take an impression of the cavity for inlay and onlay. A true polyether, this brand-new formulation results in a superfast setting reaction. They are hydrophilic, which facilitates the contact of the unset material with the intraoral tissue and the wetting of the impression by cast materials. That way the dentist and dental technician will be able to produce ideal restorations that perfectly fit in the patient’s mouth. Polyethers are elastomeric materials commonly used for making precision impressions. Restorations such as crowns, bridges, inlays, and onlays require very precise impressions. There are many different brands and techniques available on the market. 3M ESPE Imprint 3 VPS Impression Materials.
