Effect of glazing and polishing of Zirconia Reinforced lithium Disilicate(VITA Suprinity) And lithium Disilicate (IPS e.max CAD) on the wear and surface roughness of Human Enamel An in-vitro study
Yehia El Zanaty,Nadia Fahmy, Jylan Elguindy
Abstract
Tooth wear is a normal process. If the opposing restorative material does
not have similar wear properties to enamel, this will cause excessive wear of the occlusal surface.Clinical
adjustment is needed to adjust occlussal and proximal contacts or minor cervical adjustments resulting
in removal of glaze layer leading to increase the abrasive potential of the ceramic material
Keywords
wear, two body wear, surface roughness, lithium disilicate, zirconia reinforced lithium disilicate
