Abstract Self-reinforced lithium disilicate (Li 2 Si O 5 , LD) glass-ceramics were hot pressing sintered by introducing wt% Li crystal seeds into two different glass compositions of SiO -Li O-P -ZrO -Al 3 -K O-La (7C and O-K (4C LD). The results show that the play an important role in crystallization inducement, microstructural property improvement glass, especially for powder without nucleatin...

Background: The success of fixed dentures is influenced by the cementation procedure. Resin cement most commonly used luting materials. In addition to resin cement, there are other types materials, preheated composite. Preheating composite allow material have a low level viscosity, therefore can be as material. purpose this study was evaluate comparison shear strength and on indirect lithium di...

The aim of this study was to compare the effects of different porcelain polishing techniques on the color change and surface roughness of feldspathic porcelains and lithium disilicate glass-ceramic system. 80 porcelain specimens were divided into two subgroups, each subgroup was divided into 4 groups of 10 specimens. Surfaces were polished with different ceramic polishers. VITA Easyshade spectr...
