ZIRCONIUM CROWNS
ZIRCONIUM CROWNS
Zirconium crowns have translucency, giving teeth a natural appearance. In metal-ceramic crowns, light refraction occurs due to the metal in the substructure, and the teeth can have a matte appearance. The translucency of zirconium crowns closely resembles that of natural teeth, thus preventing the teeth from looking artificial.
Metal-supported porcelain crowns can create a dark line around the gums over time. Zirconium crowns, on the other hand, maintain their integrity with the gums for many years, providing a more natural appearance.
In recent years, zirconium crowns have been preferred because they offer both aesthetics and durability. Zirconium crowns have many advantages over metal-ceramic crowns.
ADVANTAGES
Especially in front teeth where aesthetics are important, zirconium offers a natural look thanks to its light-transmitting properties. Even with the best craftsmanship, achieving a perfectly aesthetic result with metal-ceramic crowns can be difficult.
While mechanical cementation is used for metal-ceramic crowns, dual cements, a combination of mechanical and chemical adhesives, are used for zirconium crowns. This method increases retention and prevents undesirable situations such as tooth fracture or dislodgement.
In metal-ceramic porcelain crowns, the nickel used in the substructure can cause allergic reactions in some patients. However, the materials used in zirconium are completely compatible with oral tissues.
The dark lines at the tooth-gum border that can be seen in metal-ceramic porcelain crowns are not seen in zirconium crowns.
In cases of gum recession, metal-ceramic crowns can create an unsightly appearance, whereas zirconium crowns do not carry this risk.
