A Comparison of Tensile Bond Strength between Low Translucency and High Translucency Lithium Disilicate Ceramics Using Two Different Resin Cements
Objectives: To compare two different dual-curing resins cement interfaces between low translucency and high translucency lithium disilicate glass-ceramics in vitro. M~aterials and Methods: ISO 11405 was modeled by using a standardized dumb-bell test to compare the tensile bond strength of two different resin cement interfaces ofa low translucency lithium disilicate ceramic to a high translucenc...
متن کاملThe Effect of Lithium Disilicate Ceramic Thickness and Translucency on Shear Bond Strength of Light-cured Resin Cement
Introduction: To achieve acceptable clinical performance, a ceramic veneer must be bonded to enamel by well-polymerized resin cement. Among different factors, thickness and translucency of the ceramic may affect the resin cement polymerization. Thus, the current study evaluated the effect of the thickness and translucency of lithium disilicate ceramic on light-cured resin cement bond strength t...
متن کاملLithium 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 کاملEffects of ceramic primers and post-silanization heat treatment on bond strength of resin cement to lithium disilicate-based ceramic
Background The silicon tetrahydride or silanes is an inorganic colourless gas with spontaneous combustion in air at room temperature [1–3]. Silane or functionalized silanes has widely industrial and medical applications, and works as coupling and impermeabilizing agent. Silane coupling agents have also been applied to bond glass and carbon fibers to polymer matrices, creating a strong adhesion ...
متن کاملThe Effect of Hydrofluoric Acid Concentration and Heat on the Bonding to Lithium Disilicate Glass Ceramic.
The aim of this study was to evaluate the effects of hydrofluoric acid (HF) concentration and previous heat treatment (PHT) on the surface morphology and micro-shear bond strength (mSBS) of a lithium disilicate glass ceramic (EMX) to resin cement. One hundred four EMX specimens were randomly assigned to two groups (n=52) according to the HF concentration: 5% and 10%. A new random distribution w...
