Abstract
The purpose of this study was to investigate the possibility on recycling of IPS Empress ceramic for the wide use of esthetically pleased IPS-Empress ceramic in clinical prosthodontic treatment. The specimens were made of first, second, and third pressed IPS Empress ceramic and were immersed in 0.05% methylene blue solution for 24hours. The amount of color change before and after stainning was measured with colorimeter(Model Tc-6Fx, Denshoku Co., Tokyo, Japan). The change of E in first pressed ceramic was 18.33 and those in second and third pressed ceramics were 19.33 and 19.93 respectively. Although there was statistical difference among them, the differences were minute and acceptable. From the results of this study, the possibility of recycling of IPS Empress ceramic could be suggested.
