Monolithic Zirconium Crowns
The type of ceramic dental crowns has zirconium oxide, which is a substance that makes it nearly unbreakable. This exceptionally strong ceramic is resistant to chips, cracks, and staining. It color-matched to your teeth, however, it’s somewhat opaque. Because of the ugly opacity of monolithic restorations, they best put in the back of the mouth.
The monolithic restorations created by cad cam milling. Large machines make these artworks from digital files made by the tech. Most of the time, only large dental labs that produce have this expensive milling equipment. Smaller labs compelled to lease them out. The only crown that is close to this power is the gold crown.
Layered zirconium crowns
As the name suggests, dental restorations that layered created using layers of lithium disilicate over the ceramic coping. The layered porcelains provide the realistic transparency required for restorations that placed in the oral cavity. The top layer of the ceramic created similarly to the IPS e.max versions.
They made of strong cores covered with layers of soft reflective porcelain. The method by which the ceramist creates the cap affects its strength and beauty. An expert ceramist can produce stunning restorations.
The ones with layers are more vulnerable to chipping as compared to PFM crowns. The gorgeous porcelain may chip easily.
