Yttrium-partially stabilized zirconium dioxide posts: an approach to restoring coronally compromised nonvital teeth.
In the pursuit of esthetic restorations for nonvital teeth, the introduction of a tooth-colored intraradicular post system is described. Conventional metallic posts can corrode and may cause inflammatory reactions and discoloration of the periodontium. Zirconium dioxide is a chemically stable ceramic with physical and optical properties that make it an ideal choice for the construction of esthetic, life-like restorations. The purpose of this study was to describe the composition, properties, and practical applications of zirconia posts in clinical practice.
