Abstract

Background and Aim: Cold- cure acrylic resins which are used in fabricating inlay patterns, cast dowel- cores, bite registration records and soldering indices may undergo dimensional changes from fabricating to casting time. The aim of this study was to compare dimensional changes of SELF - cure Duralay acrylic resins in different STORAGE MEDIA.Materials and Methods: In this experimental study, twenty samples were made by Duralay acrylic resin in a brass mold (20x 12x3 mm). After polymerization, the samples were divided into two groups of ten and stored in two STORAGE MEDIA (water and air). The samples' dimensions were measured at 0, 1 and 9 hours by a digital caliper. The data were analyzed statistically using t - student test.Results: There was not significant difference in the rate of Duralay resin shrinkage between hydrous (0.04±0.01) and dry (0.04±0.01) environments at 0 to 1 hour period. The shrinkage continued in the dry environment for 9 hours (0.08±0.02), however; it stopped in the water environment at the same interval (0.03±0.01).Conclusion: The STORAGE MEDIA does not affect the DIMENSIONAL STABILITY if the Duralay acrylic samples are invested in an hour. If the delay time is more than one hour the samples should be preserved in water.
