Color Aspect of Monolithic Zirconia Restorations: A Review of the Literature

Abstract: Monolithic zirconia restoration is an acceptable treatment option in restorative dentistry and a developing trend in esthetic dentistry. Digital dentistry has simplified fabrication of monolithic zirconia restorations. Zirconia ceramic has introduced an opportunity to achieve both esthetic and mechanical requirements for restorations. This is rarely found for a ceramic in dentistry. Monolithic zirconia restorations represent an acceptable durability, comparable to metal-ceramic restorations, while they are sup… Show more

“…This can be explained by the higher content of Yttria (Y 2 O 3 ) (6.5‐8%) in comparison with the other materials tested (Katana, Cercon, Vita YZ) (Yttria content 4‐6%), which favors the formation of cubic phase in addition to tetragonal phase in the composition of zirconia. Cubic phase increases the translucency by avoiding the high scattering and birefringence of light that is characteristic for the tetragonal zirconia …”

“…Although it is necessary to veneer zirconia surfaces to improve the esthetic values of restorations, such bilayer systems have several major drawbacks, such as chipping . The obvious way to overcome these drawbacks is to replace the core and the veneer bilayer with a monolithic zirconia (MZ) . Currently, producing full‐contour restorations using MZ has become more common as it has some advantages, such as a reduced material thickness, fast fabrication, and reduced chipping .…”

“…The disadvantages of composite resin as polymerization shrinkage, porosities, inhomogeneity, and lack of color stability have been reported as most challenging problems . Conventional and milled ceramic restorations have also shortcomings such as lack of proper esthetics because of their monochromatic appearance, brittleness, and susceptibility to chipping fracture . To overcome these disadvantages and to combine the advantageous properties of composite resin and ceramic, CAD/CAM materials like resin nano‐ceramic and polymer‐infiltrated ceramic network materials have been fabricated .…”
