Zirconia Crowns VS Porcelain Fused to Metal Crowns

When discussing dental crowns, it is normal for patients to doubt whether they are the best option, which is the best material, etc. Taking that into account, we have created an article that has the necessary information for you to clear these doubts.

Dental crowns, what are they, and when are they used?


It is a cover that provides more strength to a dental piece and, at the same time, protects it. Usually, this treatment is recommended for patients with a healthy inner part of the tooth, but the outer part has some damage.

Porcelain Fused To Metal Dental Crown

As its name indicates, it is a crown that combines these two materials, and it is the most commonly employed option. The inner part is made of metal, while the outer part is a porcelain covering, giving the tooth a more realistic appearance.

Some metals commonly used for porcelain metal crowns are Chrome nickel, chrome cobalt and gold. However, cobalt chrome alloy is generally used.

Good resistance

One of the main characteristics of porcelain fused to metal crowns is that they are usually quite resistant. That is why it is common for dentists to suggest their use on molar and premolar teeth, as these are the places where the most force is applied when chewing food.

Natural appearance

One of the most common fears of patients who are going to have porcelain fused to metal crowns placed is that they will look unnatural. The truth is that as long as these materials are properly worked, the tooth will have a natural and aesthetic appearance.

Affordable price

One of the main benefits of this kind of crown is that the price is usually lower than that of other materials, such as pure porcelain or zirconium crowns. That is why it is usually one of the most requested options by patients.

Main disadvantages

Some of the main disadvantages of porcelain fused to metal crowns are: the risk of allergies, the shadowing effect that causes teeth to look bad, and, over time, the gums may recede, making the metal visible. The tooth also wears out more at the preparation time since more space is required because the material is thicker. 

Zirconium crowns

In this case, there are two options, the total zirconium crowns and the crowns that only have the internal part of zirconium, and the rest is ceramic. Both are good options, and the choice depends on the patient’s needs.

Greater resistance

In addition to providing the patient with more lightness in the mouth compared to porcelain metal crowns, they are much more resistant. They are usually 50% stronger than porcelain fused to metal crowns.

It doesn’t cause allergies.

As we said before, some of the metals used in porcelain fused to metal crowns can lead to health problems such as allergies. In that sense, the main advantage of dental zirconia is that it is compatible with the human organism, preventing any allergy.

A natural tooth

One characteristic of zirconium crowns is that, due to their white color, the crowns look just like natural teeth. Contain no metal, and, in addition, the dental crown can be used for a more extended period.

Improved hygiene

It is common for dental plaque to affect dental crowns if proper hygiene is not followed. However, with zirconia crowns, the problem is reduced because one of the characteristics of zirconium is that it limits adherence to dental plaque.

It does not heat up

One of the most common complaints for patients with porcelain fused to metal crowns is that they may have unpleasant sensations due to cold or heat. On the other hand, zirconium has low thermal conductivity.

In other words, the patient can enjoy his favorite dishes regardless of whether they are hot or cold.

Main disadvantages

We can say that the only disadvantage of zirconium dental crowns is that the price is usually a little higher. But there are many reasons for this, the first one being that it is a relatively expensive material, and a unique technology must be employed to make these crowns.


Both zirconium crowns and porcelain fused to metal crowns can be good alternatives as long as they are made by a professional. A dentist in Tijuana generally prefers zirconium crowns because of the benefits they can provide to patients.  That is why we do not make metal-porcelain crowns at Molar House since it has more disadvantages than those made of zirconia. We also have the equipment to place zirconia crowns the same day the impression is taken, so it will not be necessary to make multiple visits to the dentist.

Molar House was born with the dream of being able to provide patients with everything they need to achieve good dental health. That is why we guarantee our patients honest and quality treatment to ensure they have the confidence they need.
