Abstract:

Monolithic zirconia crowns fabricated by computer-aided design/computer-assisted manufacturing equipment possess extraordinary mechanical properties and excellent biocompatibility. Unlike traditional zirconia crowns, monolithic zirconia crowns eliminate the veneering ceramic layer’s need, which reduces the risk of veneering ceramic chipping and the required tooth reduction. Traditional zirconia is poor in aesthetic performance because of its inherent whitish color and high opacity. Recently, improved translucency and various coloring technologies have dramatically improved the aesthetic performance of monolithic zirconia crowns and vastly broadened the range of its applications in prosthetic dentistry. However, the final prosthesis performance of monolithic zirconia crowns is often affected by various clinical parameters, such as dental background, dental crown thickness, cement, surface finishing protocols and low-temperature degradation. This paper reviewed the factors influencing the aesthetics of monolithic zirconia crowns to assist the selection of monolithic zirconia crowns for dentists.

Key words: full-contour monolithic zirconia crown, monolithic zirconia crowns, esthetic prosthesis, translucency, color, clinical factors
