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 کاملEffect of Repeated Firings on Microtensile Bond Strength of Bi-layered Lithium Disilicate Ceramics (e.max CAD and e.max Press).
AIM To achieve acceptable contour, color, esthetics, and occlusal relations, the porcelain may be subjected to several firing cycles. This study sought to assess the effect of multiple firing cycles on the microtensile bond strength (MTBS) of lithium disilicate-based ceramics (e.max Press, e.max CAD). MATERIALS AND METHODS IPS e.max computer aided design (CAD) cores were fabricated using CAD/...
متن کاملEffect of hydrofluoric acid etching duration on the roughness and flexural strength of a lithium disilicate-based glass ceramic.
The aim of this study was to examine the effect of different acid etching times on the surface roughness and flexural strength of a lithium disilicate-based glass ceramic. Ceramic bar-shaped specimens (16 mm x 2 mm x 2 mm) were produced from ceramic blocks. All specimens were polished and sonically cleaned in distilled water. Specimens were randomly divided into 5 groups (n=15). Group A (contro...
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...
متن کاملWear of primary teeth caused by opposed all-ceramic or stainless steel crowns
PURPOSE This study was conducted to evaluate the effects of full-coverage all-ceramic zirconia, lithium disilicate glass-ceramic, leucite glass-ceramic, or stainless steel crowns on antagonistic primary tooth wear. MATERIALS AND METHODS There were four study groups: the stainless steel (Steel) group, the leucite glass-ceramic (Leucite) group, the lithium disilicate glass-ceramic (Lithium) gro...
