Allow approximately 10 minutes to air-dry so that the adhesive becomes tacky. One is very thick and is used in the tray. In this study, we examined the rheological properties of elastomeric impression materials, both before and during setting, to assess the clinical significance of certain key characteristics such as viscosity, pseudo-plasticity, and the rate of development of elasticity. Their ability to reproduce fine details [13,14], Purpose. Results: Addition silicones provided dies which were shorter in height and bigger in diameter. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Hybrid materials, such as Identium® (Kettenbach) and EXA’lence™ (GC America), are PVS with grafted polyether functional chains that claim to combine advantages of both types of impression materials—the hydrophilicity of polyethers and the tear strength of PVS. methods of manipulation. Explain the tray preparation that is necessary for use of addition silicone impression material. o As per ADA Sp. 2. Classification of Elastomeric Impression materials: Till now the elastomeric impression materials are divided into 3 types based on the material used. Its stability and accuracy make it a very popular material. [Article in Greek, Modern] Anagnostopoulos T, Tsokas K. A review of the literature on elastomeric impression materials, is presented in this paper. Elastomeric impression materials Polysulfide (hydrophobic) Silicones Polyether (hydrophilic) Condensation Silicone (hydrophobic) Addition silicone Hydrophobic type … Casts thus obtained were evaluated under a traveling microscope to evaluate various dimensional changes. Elastomeric impression materials have been widely used across the globe for the last 50 years and are considered to be a gold standard among den-tal impression materials used in fixed prosthodon-tics. This material commonly involves the use of an automix gun, as shown in Figure 8.14. The final cure of an elastomeric impression material can occur ___.
