Translucency of different pressable lithium silicate ceramics with two thicknesses - An in vitro study -

Abstract

Ceramic Restoration have gained Fame and are now applied in daily practice. Their esthetics, durability, and biocompatibility have made their use recently expanded, mainly due to the superior Optical properties of new glass ceramics and to the improvement of the cementation strategies. Porcelain laminate veneers of minimum thickness provide satisfactory esthetic results and biocompatibility. Clinicians and Patients are nowadays seeking esthetics with restorations of Shade, Shape and Translucency close to that of natural teeth. The current study evaluated the Translucency of different pressable lithium silicate Ceramics with two thicknesses before and after aging. Fourty-two wax specimens were machined then pressed finished and glazed.
