Research progress and prospects of colored zirconia ceramics: A review

Abstract

Owing to their rich color, excellent mechanical properties, and favorable biocompatibility, colored zirconia ceramics have been widely used in intelligent terminals, dental restoration, colored decorations, and other potential fields. This paper starts with the challenges faced by colored zirconia ceramics, followed by a summary of the application market of colored zirconia ceramics. Herein, we review various types of colorants and their mechanism of color development, summarize coloring methods, and analyze their advantages and disadvantages. Finally, the research progress on zirconia ceramics with red, blue, black, and other common colors is summarized, and future development directions are proposed in this review.
