What is the most remarkable advantage of zirconium crowns?

Zirconium is an infrastructure (supportive) material; since it is white in color, its harmony with porcelain superstructure will have better aesthetic outcomes than metallic infrastructures. Accordingly, most remarkable advantage of zirconium used as a base for porcelain restorations originates from aesthetic features. They ensure total harmony with natural teeth, thanks to their light transmittance. Thereby, a perfect aesthetic outcome can be achieved.

Since quality of aesthetic appearance is high and light transmittance is strong, appearance is very close to that of natural teeth. Since porcelain blocks are prepared utilizing digital techniques completely, error rate is minimized. Moreover, some studies had proven that harmony of zirconium with gums is better than that of metallic infrastructures.
