Exploring the Types of Crowns Used in Dental Restorations

Which crown material is right for you?

When a patient undergoes a restorative procedure that requires a dental crown to be placed, there is a choice to be made about which crown material or type to use.

What exactly is a dental crown?

dental crown is a tooth-shaped restoration that caps” over the remaining portion of a patients natural tooth, restoring strength, function and appearance. It is standard for root canal treatment to conclude with a dental crown fitting to help strengthen and protect the treated tooth from any damage moving forward.

 

When it comes to dental crowns, there are many materials that a patient can choose from to best suit their needs.

 

Lets talk about some of the different types of crowns our Toronto dentist is able to provide patients with today, as well as what sets them apart from each other:

1. Porcelain crowns

A popular choice among patients, porcelain crowns blend in with the appearance of the natural teeth and, compared to the other crown materials, provide the most realistic looking result. However, because porcelain crowns are not completely resistant to breaking, they are best used to restore front teeth that are not exposed to as much biting force.

2. Zirconia (ceramic) crowns

Composed from zirconium dioxide, a highly durable type of ceramic material, zirconia crowns are an excellent choice for restoring either the back or front (visible) teeth while also providing a realistic and natural-looking result. Furthermore, since zirconia crowns are so strong and substantial, the dentist will not need to perform as much invasive preparation of the natural tooth prior to fitting.

3. E-Max (all-ceramic) crowns

Even more strong and durable than zirconia crowns, the E-Max crown is composed of lithium desilicated ceramic – a material harvested for its resilience and translucent colour. And, because of its translucent quality, this material can provide an even more natural-looking result than zirconia crowns. While E-Max crowns may be the most expensive type of crown, it is certainly for good reason.

4. Resin Crowns

Resin, or composite resin is the tooth-coloured material that is used to fill cavities today. These crowns are also best used to restore front teeth as they are not resistant to fracture under intense chewing forces. They are the least expensive option when compared to other crown materials.

5. Metal Crowns

Crowns can also be composed of a mixture of gold and other metals, which is known to be extremely strong and resistant to fracturing or breaking. Crowns can also be composed of base metal alloys which are also very resistant to wear. While these types of crowns may not be a top choice for cosmetic reasons, they are definitely a top choice when considering longevity and strength.
