Lithium Disilicate Glass-Ceramic
ceramic on light transmission of light-emitting diode (LED) and quartz-tungsten-halogen units (QTH) were evaluated. Ceramic IPS e.max CAD shades A1, A2, A3, A3.5, high (HT) and low (LT) translucency were cut (1, 2, 3, 4 and 5 mm). Light sources emission spectra were determined. Light intensity incident and transmitted through each ceramic sample was measured to determine light transmission perc...
متن کاملThe Zirconia: a new dental ceramic material. An overview.
Yttrium tetragonal Zirconia polycrystals (Y-TZP) based systems are the more recent addition in to the high-strength all-ceramic systems that are used for crowns and fixed partial dentures. CAD/CAM produced Y-TZP based systems are being used and are said to be in demand in the aesthetic zone and in stress bearing regions as well. This systematic overview covers results of recent scientific studi...
متن کاملEvaluating The Opacity of Two Super high Translucent Zirconia and Lithium Disilicate Reinforced Glass Ceramic
Abstract Background and Aim: The opacity of dental ceramics has important role in final appearance of all ceramic restorations. opacity of super high translucent zirconia is not clearly determined.The aim of this study was evaluating the opacity of two super high translucent zirconia (zolid fx and DD cubeX2 ) and lithium disilicate reinforced glass ceramic(IPS e.max CAD LT). Materials and Metho...
متن کاملIn vitro study of the fracture resistance of monolithic lithium disilicate, monolithic zirconia, and lithium disilicate pressed on zirconia for three-unit fixed dental prostheses
PURPOSE The purpose of this study was to determine fracture resistance and failure modes of three-unit fixed dental prostheses (FDPs) made of lithium disilicate pressed on zirconia (LZ), monolithic lithium disilicate (ML), and monolithic zirconia (MZ). MATERIALS AND METHODS Co-Cr alloy three-unit metal FDPs model with maxillary first premolar and first molar abutments was fabricated. Three di...
متن کاملMultifunctional uses of a novel ceramic-lithium disilicate.
Objective: To familiarize the reader with the material characteristics of and indications for lithium disilicate ceramic. Summary: This paper is part of the Journal's "Masters of Esthetic Dentistry" feature. Lithium disilicate is a glass ceramic material that can be used to form restorations using either a lost-wax hot pressing technique or CAD/CAM milling procedures. Although the pressable and...
