Background: Effects of ceramic translucency, layer thickness, and substrate colour on the shade of lithium disilicate glass-ceramic restorations proved to be significant in several studies, however, quantitative, numerical results on the relationship between the colour difference and these parameters are still lacking. The purpose of this in vitro study was to quantitatively determine how the colour reproduction ability of a lithium disilicate glass-ceramic is affected by its translucency, layer thickness, and substrate colour.
Methods: Ceramic samples were prepared from A2 shade IPS e.
Objective: The aim of this in vitro study is to evaluate the masking ability of polymer-infiltrated ceramic-network materials (PICN) with different translucencies and thicknesses on multiple types of substrates.
Materials And Methods: Ceramic samples were prepared of VITA ENAMIC blocks in two different translucencies (2M2-T, 2M2-HT) in a thickness range of 0.5-2.
Objective: The aim of this in vitro study was to evaluate the effects of substrate colors, different levels of ceramic thickness and translucency, and cement shades on the color difference from a reference color of lithium-disilicate crowns.
Materials And Methods: A premolar tooth preparation was made on a study model for 1.0 and 1.
The medical and dental history is one of the crucial part of the routine dental practice. According to a survey performed in 2001 27% of the total Hungarian population was above the age of 60. The prognosis forecasts an increasing tendency in life expectancy and an even higher percentage of elderly population in the foreseeable future.
