Types of Dental Crowns

 

What is a dental crown?

A dental crown is also called a cap. It is a fixed prosthetic object that is cemented over the tooth. The main objective of getting a dental crown is to cover the damaged tooth, but at the same time, it strengthens the tooth and improves its overall appearance and teeth alignment. These crowns are installed by a dentist, and only a dentist can remove them.

Crowns are made by taking the impression of the tooth or the teeth they are supposed to cover. Before this impression is made, the dentist will reduce the tooth size so that the crown fits perfectly.

What are the types of dental crowns?

Types of Dental crown depend on the material from which the crown is made. The various types of dental crowns are:

1.      Gold crowns

They are a combination of copper and various other metals e.g., nickel or chromium. Gold crowns are known for their strength and durability. They also last a long time if proper care is taken. These crowns wear down very slowly, similarly to wearing down of the natural enamel. Therefore, they are ideal for posterior tooth restorations, especially the second molars. However, nowadays, gold crowns have lost their popularity due to the aesthetics and colors of the same. Also, some people have reported side effects such as allergic reactions or swelling due to gold crowns.

2.      All Porcelain crown

These are one of the most in-use dental crowns nowadays. They provide a natural look and match the surrounding shape, size, and color of your teeth. They are considered biocompatible, which means no metal is used. Therefore, they are entirely toxic-free crowns. As a result, they are the best options for front teeth restoration. However, there are certain disadvantages to these crowns, such as they are not as strong as metal crowns, and they are costly as well.

3.      Porcelain fused to metal crowns (PFM)

Porcelain fused to metal crowns is a widely used dental crown. They provide strength as well as aesthetic. The metal structure gives them strength, and the porcelain coat that covers the cap gives them proper aesthetics. These dental crowns have been popular for about 50 years, and at the same time, they are less costly than all-porcelain crowns. However, the main problem with these crowns is that they leave a grey line on the gum line, which alters its aesthetic look.

4.      Zirconia Crowns

 They come in varieties of high translucent zirconia and layered zirconia crowns. They are strong, long-lasting, provide great aesthetic, less likely to wear off, less time consuming, and are biocompatible as well. But solid zirconia is a bit difficult to adjust, and their strength can make the teeth they bite against to wear off quite easily.

 

5.  E-MAX: Lithium Disilicate crowns

They are the newest types of dental crowns in the market. It is another type of all-ceramic crown which is made out of lithium disilicate. They provide great aesthetics and are very durable, as well. On the other hand, they could be quite expensive.

These are the five main types of dental crowns.
