Zirconia or Metal Crowns: Which to Choose?

Zirconia crowns are one of the most modern and popular options when it comes to restoring damaged or weakened teeth, while metal crowns are known for their durability.

Both types of dental crowns have advantages and disadvantages, which can cause confusion when deciding which is the most suitable. In this article, we will explain the differences between zirconia crowns and metal crowns so you can make an informed decision based on your needs.

Zirconia crowns: 

Zirconia crowns are made from zirconium dioxide, a highly resistant ceramic material that has earned its place in dentistry due to its combination of durability and aesthetics. Here are the advantages and disadvantages of this option.

Advantages of Zirconia crowns:

1. Superior aesthetics: One of the main reasons many patients choose zirconia crowns is for their excellent aesthetics. Zirconia has a natural white color that can be adjusted to match the tone of the surrounding teeth, providing a very natural appearance. This makes them an excellent option for visible teeth, such as the front ones.
2. Biocompatibility: Zirconia is a biocompatible material, meaning it is well tolerated by oral tissues. This reduces the risk of allergic reactions or gum irritation, making it a safe option for most patients.
3. Extreme resistance: Zirconia crowns are incredibly strong and durable. They can withstand chewing forces without wearing down easily, making them suitable for molars that endure more pressure during chewing.
4. Less wear on opposing teeth: Although zirconia is a hard material, it is less abrasive compared to other materials like metal, reducing the risk of wear on the opposing teeth that come into contact with the crown.

Disadvantages of Zirconia crowns:

1. Higher cost: Due to the material and advanced technology used to create them, zirconia crowns are generally more expensive than metal crowns.
2. Material hardness: While strength is an advantage, in some cases, the hardness of zirconia can be a drawback. If the crown’s fit is not perfect, it may cause additional pressure on the underlying tooth, leading to long-term discomfort.

Metal crowns:

Metal crowns have been a reliable option in dentistry for many years. These crowns are made from metal alloys such as gold, platinum, or nickel, and while their appearance is not the most aesthetic, their durability makes them a popular choice for molars.

Advantages of metal crowns:

1. • Unmatched durability: Metal crowns are extremely strong and durable. They can withstand intense chewing forces without breaking or wearing down, making them the best option for restoring molars.
2. • Less wear on opposing teeth: Despite their hardness, metal crowns have a smooth surface that does not significantly wear down opposing teeth, which is beneficial for overall oral health.
3. • More affordable: Compared to zirconia crowns, metal crowns are generally more affordable. This makes them a viable option for those seeking a durable solution without a high cost.
4. • Easier placement: Due to the properties of metal, these crowns require less removal of the original tooth for placement, meaning the procedure is less invasive.

Disadvantages of metal crowns:

1. • Unesthetic appearance: The biggest drawback of metal crowns is their appearance. The metallic color makes them unsuitable for visible teeth, as they do not resemble natural teeth.
2. • Possible allergies: Some people may have allergic reactions to the metals used in crowns, especially in cases where the alloy contains nickel.

Factors to consider when choosing between zirconia or metal crowns 

Choosing between zirconia crowns or metal crowns depends on several factors that should be carefully considered. Here are the main elements to keep in mind:

1. • Aesthetics: If appearance is a priority, zirconia crowns are the best option. Their natural white color and ability to be customized make them ideal for front teeth, where aesthetics are crucial. Metal crowns, on the other hand, are more suitable for molars, where appearance is less important.
2. • Durability: While both options are durable, metal crowns are known for being nearly indestructible. They are ideal for people with intense chewing habits or who suffer from bruxism. Zirconia crowns are also very strong, but they do not reach the same level of durability as metal crowns in extreme cases.
3. • Cost: Budget is a determining factor. Metal crowns tend to be more affordable than zirconia crowns, which may influence the decision, especially if multiple crowns are needed. However, the investment in zirconia may be justified by their superior aesthetics.
4. • Biocompatibility and allergic reactions: Zirconia is more biocompatible, making it a better option for those with sensitivities or allergies to metals.
5. • Location of the tooth: Zirconia crowns are more suitable for visible teeth, while metal crowns work better for molars, which bear the most chewing pressure.
