The Advantages And Disadvantages Of Zirconia Dental Crowns


Clinicians who wish to provide patients with excellent
dental restorations often choose zirconia crowns.
These crowns are chosen over conventional PFMs
(Porcelain Fused to Metal) or full-gold crowns due to:

● Superior strength
● Durability
● Excellent aesthetics


● Has a natural translucency and opalescence
● Generally recommended for posterior crowns.
● Particularly suitable for patients who may grind their teeth because of its high strength.
● Only minimal clearance is required and there is low wear on opposing teeth.
● Very effective for masking highly discolored dental preps, specifically those that have darkened due to previous dental treatments


● More translucent and opalescent.
● Especially suitable for anterior crowns.
● May also be used for posterior crowns if there is sufficient clearance from other teeth.
● When done skillfully, the very best aesthetic results can be achieved.


Both solid and layered zirconia crowns have a strength and consistency that is comparable with traditional PFM restorations, yet they provide far superior aesthetics.


● Zirconia crowns are highly biocompatible, as the smooth surface helps to reduce plaque accumulation.
● Solid zirconia crowns are extremely strong.
● Chipping and fracturing are extremely rare.
● The material promotes a healthy tissue response.
● Suitable for patients with metal allergies or who would prefer to have metal-free restorations.
● Zirconia is metal-free, which prevents darkening around the gingival area.


● Eliminates the possibility of metal margins becoming exposed due to gum recession.
● The translucent nature of zirconia can transmit the color of adjacent teeth and it is manufactured in a wide variety of shades, making it easy to accurately match the color of the patient’s natural teeth.
● Crowns can be conventionally cemented in place using traditional bonding techniques.
● Zirconia crowns are comfortable for patients, as they do not transmit hot and cold in the same way as conventional PFMs.


The disadvantages of zirconia crowns are minimal.

The toughness of the material has raised some concerns about friction against the tooth root and wearing down opposing teeth. Frequent checks, however, help to reduce any possible risks to opposing teeth.

    It’s great to know that there are dental crown options out there for people who have metal allergies. I’ve heard a lot of good things about these from my friends, but most of them used metal for their treatments and I have a very violent reaction to anything metal being in my mouth. To help with this, I’ll take your advice about it and get zirconia crowns from any dentist in the area that offers them.
