    Comparison of Color Stability Between Monolithic Zirconia Stained and Glazed with MiYO Esthetic System and Lithium Disilicate Ceramic
    Author(s): Zanyar M Kareem* and Bassam K Amin

    Background/Objective: CAD/CAM-made monolithic zirconia restoration has excellent mechanical properties but limited esthetic characteristics due to low translucency. Various techniques were undertaken to enhance their translucency and esthetic. Staining zirconia by MiYO liquid ceramic system is one of these techniques. This study aimed to evaluate the color stability of the MiYO-treated monolithic zirconia and compare it with layered lithium disilicate ceramic Material and Method: Thirty ceramic specimens were prepared in the dimension of (20mm*15mm*2mm) and divided into two groups, fifteen monolithic zirconia specimens stained at two color zones with MiYO esthetic system, and fifteen lithium disilicate specimens. Both groups were subjected to thermal aging. The CIE L*a*b* color parameters were measured using the dental spectrophotometer to determine the color stability by using the co.. Read More»
