If the stress under a load becomes too high, then when the load is removed, the material no longer comes back to its original shape and size, but relaxes to a different shape and size: The material becomes permanently deformed. Impression materials are selected because of their unique qualities that allow dentists to obtain the most accurate reproduction. 0000005400 00000 n A low elastic modulus is typical for materials that are easily deformed under a load; for example, a rubber band. Reversible Hydrocolloid is the most precise and detailed impression material available in dentistry. that the material is a superior or inferior product. Monet’s painting Impression: Sunrise (1872) earned them the initially derisive name “Impressionists” from the journalist Louis Leroy writing in the satirical magazine Le Charivari in 1874. 0000017246 00000 n They are easy to handle and their accuracy is pretty good. 0000001815 00000 n 128 0 obj <>/Filter/FlateDecode/ID[<32D4EC79B97ECAF2B74D8E62968DDF3C><16D10181EB969041A0E02FF1DF129E86>]/Index[100 51]/Info 99 0 R/Length 125/Prev 610082/Root 101 0 R/Size 151/Type/XRef/W[1 3 1]>>stream As a result, much research has been devoted to measuring the accuracy of elastic impression materials. The elastic impression materials are most generally used for the making of impressions for removable partial dentures, immediate dentures, and crowns and fixed partial dentures when tooth and tissue undercuts and surface detail must be recorded with accuracy. Partial Dentures 0000001587 00000 n Elastic materials have a soft consistency but after setting, they become elastic. 2. The visco-elastic properties of a number of set elastomeric impression materials were determined using a torsional pendulum apparatus i.e. 0000011438 00000 n One technique for recording impressions of undercut areas, commonly used before the advent of elastic materials, was to allow the impression plaster to ‘set’ and then to fracture it in order to facilitate removal from the mouth. Start studying Elastomeric Impression Materials. The two types of material are inelastic and elastic.

Resistance to this movement is called viscosity.1 The flow characteristics of a material are the basis for the science of rheology.12 The correlation of shear stress and shear rate determines the behavior of the material and can be described as either Newtonian (where viscosity is not affected by shear stress)—of which water is an example—or non-Newtonian.
