What Is a Dental Crown? 

A crown replaces/restores the damaged portions of the tooth. Even though it is an artificial prosthesis it exactly simulates the size, shape and shade of a natural tooth. A crown can safeguard a tooth while also improving its appearance. A dental crown can be made up of a variety of materials.

We can easily relate the shape of a dental crown simply by imagining a hat on top of our tooth or like it’s a helmet for our tooth.

Who needs a dental crown?

You may need a dental crown for various reasons, including:

• Fractured tooth
• Discolored tooth
• Severely worn tooth 
• Poor remaining tooth structure
• A tooth with a very large filling
• Abnormal tooth size/ shape
• Root canal treated tooth
• Replace missing teeth with crown & bridge
• Cover a dental implant

What are the different types of dental crowns?

Crowns are available in a variety of materials. Metal alloys, all ceramics, porcelain fused to metal, and are some of the materials that can be used. Only in olden day movies, we can see people with golden color artificial teeth, but in reality, people prefer tooth color material that mimics our natural teeth.

Metal crowns:

Precious & Nonprecious metals (Gold, palladium, nickel, and chromium are some of the metals that can be used in dental crowns. Metal crowns are the least likely to chip or shatter, last the longest in terms of wear, and need only a modest amount of tooth removal. They’re also resistant to biting and chewing. The biggest disadvantage of this sort of crown is the metallic color. Metal crowns are mostly indicated in the nonvisible zone like the molar region.

Porcelain-fused-to-metal

The color of the teeth next to the crown can be matched with this type of dental crown. The hue of their teeth is more natural. However, the metal behind the porcelain cover of the crown occasionally peeks through as a dark line and the metal coping won’t allow the light to pass easily. So the color match is not that great. Other disadvantages include the possibility of the porcelain piece (tooth color portion) of the crown chipping or breaking off, as well as the crown-wearing down the teeth opposite it in the mouth. For front or back teeth, porcelain-fused-to-metal dental crowns can be a viable option.

All-Ceramic Crown

When compared to other crown varieties, all-ceramic or all-porcelain dental crowns have the best natural color match. They’re also a fantastic option if you’re allergic to metals. They are not, however, as durable as porcelain-fused-to-metal crowns. They can also wear down the teeth on the opposite side of the mouth more than metal or resin crowns. For front teeth, all-ceramic crowns are a viable option.

Zirconia crown

Dental crowns made of pressed ceramic have a firm inner core. The metal liner used in the all-ceramic crown-making method is replaced with pressed ceramic dental crowns. Porcelain crowns are capped with pressed ceramic crowns for the greatest natural colour match. In addition, they survive longer than an all-porcelain crown.

Acrylic resin: Dental crowns composed of resin are less expensive than other types of crowns. They are mostly used for temporary purposes and indicated for front teeth only. However, unlike porcelain-fused-to-metal crowns, they deteriorate over time and are more likely to break.

What is the procedure to prepare a tooth for a dental crown?

To prepare for a dental crown, you’ll usually need two appointments with Sakti dental. 

Initial visit

The tooth that will get the crown is evaluated and prepared on the initial visit. X-rays of the tooth and its surrounding bone are taken. If you have a deep cavity/ fracture tooth/discolored tooth, we may need to perform a root canal treatment before placing your dental crown.

The top and sides of the tooth that will receive the crown will be filed down. This will create a small space for the crown. The quantity of tooth that is reduced is determined by the crown type. All-metal dental crowns are thinner than all-porcelain or porcelain-fused-to-metal crowns and require less tooth preparation.

After the tooth has been reshaped, a paste or putty is used to make a copy (also known as an impression) of the tooth that will receive the crown. We take the opposing arch impressions also to prepare a dental crown with proper tooth contact. This is done to ensure that the crown does not interfere with your bite.

The best and India’s largest dental lab -Dentcare receives your models. The computer software generates a 3D model of the tooth. The digital design is then transported to another machine, which carves the crown shape out of a block of ceramic. Computer-aided design/computer-aided manufacturing (CAD/CAM) is the process of creating a dental crown. 

The crowns are made in a laboratory as per our instructions and delivered to us in a couple of days. We usually build a chairside temporary crown to cover and preserve the prepped tooth while you wait for the permanent crown during your first office visit.

Second visit

The permanent crown is placed on your tooth at this second visit. 

The temporary crown is removed first, and the permanent crown’s fit and color are assessed. If all goes well, the new crown is permanently set in place.
