Comparison of light transmittance in different thicknesses of zirconia under various light curing units
PURPOSE The objective of this study was to compare the light transmittance of zirconia in different thicknesses using various light curing units. MATERIALS AND METHODS A total of 21 disc-shaped zirconia specimens (5 mm in diameter) in different thicknesses (0.3, 0.5 and 0.8 mm) were prepared. The light transmittance of the specimens under three different light-curing units (quartz tungsten ha...
متن کاملLight transmittance of zirconia as a function of thickness and microhardness of resin cements under different thicknesses of zirconia
OBJECTIVE The objective of this study was to compare microhardness of resin cements under different thicknesses of zirconia and the light transmittance of zirconia as a function of thickness. STUDY DESIGN A total of 126 disc-shaped specimens (2 mm in height and 5 mm in diameter) were prepared from dual-cured resin cements (RelyX Unicem, Panavia F and Clearfil SA cement). Photoactivation was p...
متن کاملZirconia a Bio-inert Implant Material
Implant ology has become a choice for replacement of missing teeth. Replacements in the anterior zone where aesthetic concern are important were new aesthetic materials are being used. Traditionally Titanium which has been used for past three decades has limitations like hypersensitivity and lack of aesthetics. Zirconia is now being introduced as an aesthetic alternative for implant placement. ...
متن کاملAngular Transmittance Analysis of a Novel Thermotropic Material
This paper uses inverse adding-doubling (IAD) method and Monte Carlo method for the simulation of the spectral angular transmittance of a novel kind of thermotropic material at different temperatures. The results show that the collimated light takes the major part at the beginning of the switching process and the scattered light is negligible. However, the scattered light increased to high abov...
متن کاملOxygen-Deficient Zirconia (ZrO2−x): A New Material for Solar Light Absorption
Here, we present oxygen-deficient black ZrO2-x as a new material for sunlight absorption with a low band gap around ~1.5 eV, via a controlled magnesiothermic reduction in 5% H2/Ar from white ZrO2, a wide bandgap(~5 eV) semiconductor, usually not considered for solar light absorption. It shows for the first time a dramatic increase in solar light absorbance and significant activity for solar lig...
