Zirconia crowns are made from zirconium dioxide, a very durable type of metal that’s related to titanium, although it’s categorized as a type of ceramic crown.
They somewhat resemble the color of teeth giving it more aesthetic appearance.
Durable.
Zirconia is biocompatible as it causes no reaction with body or surrounding tissues.
Zirconia can be layered with porcelain for an even more tooth-like aesthetic.
Expensive as compared to metal ceramic crowns.
Light in weight.
The translucent nature of this material can transmit the color of adjacent teeth which makes it easy to accurately match the color of the patient’s natural teeth.
Suitable for patients with metal allergy.
Prevents darkening around gingival area as they are metal free.
What are metal ceramic or PFM crowns ?
Another name for this is a ‘porcelain fused to metal crown’ (PFM). They consist of a metal interior or base which is fused to porcelain crowns.
They are usually cheaper than metal free crowns.
Robust and long lasting.
Crowns are prone to chipping or fracture of ceramic layer.
Bulky and heavy as compared to metal free crowns.
“The thin black line” that can develop at the gum line can be of esthetic concern.
Ceramic turns a shade darker over a period of time.
When focused under bright light PFM looks darker in shade.
