Influence of Accelerated Aging on the Color Stability of Dental Zirconia

Abstract

After prolonged aging, discrete color changes can occur in zirconia, particularly when it is contact with the oral environment, as is the case of abutments and monolithic crowns. Thus, clinical and laboratory care should be taken to maintain surface integrity of zirconia, minimizing aging. (J Esthet Restor Dent 28:304-312, 2016).
