These are lithium disilicateglass ceramics. Total 10 rectangular specimens per material were prepared are lithium disilicateglass ceramics. Total 10 rectangular specimens per material were prepared with the dimension of 4.0×1.0×20.0 mm. According to ISO 6872:2015 specification, the specimens from each other were polished both the top and bottom surfaces with #1000-grid SiCpaper. The specimens were subjected to the three-point bending test using a universal testing machine( 15mm span at a crosshead speed of 1.0mm/min).Average flexural strength data were analyzed by Levenetest and T-test(p<0.05).Results: There was no significant difference between group EM and LS. Mean flexural strength values (MPa) and standard deviations are shown in the Table below:Conclusions: In this study, it was suggested that the new pressablelithium disilicateglass Conclusions: In this study, it was suggested that the new pressablelithium disilicateglass ceramics were clinically useful.Table(s):Disclosure Statement:EMLS506.35±59.95535.37±53.77Disclosure Statement:The submitter must disclose the names of the organizations with which any author have a relationship, the nature of the relationship, and the clinical or research area involved.
