Zirconia Crown

Dental crowns are used to cover a tooth or a dental implant. Dentists commonly utilize crowns to support broken, weak, or misshapen teeth. Additionally, dental crowns can be used to cover teeth that are severely worn or discolored. They may also be employed with bridges to strengthen multiple teeth.
When it comes to the materials used for crowns, there are several options, including ceramic and metal. Another option is zirconium coating. Although zirconium crowns are classified as a type of ceramic crown, they are crafted from zirconium dioxide, an extremely durable metal related to titanium.
What is a Dental Crown?
Dental crowns are restorations used to restore the shape, size, and appearance of a tooth. When fillings fail to solve the problem, crowns placed on damaged teeth provide protection. Crowns can be made from materials such as metal, porcelain, resin, and ceramic, requiring no special care beyond regular and adequate oral hygiene.
Crowns are typically produced in a tooth-colored shade to match natural teeth. When determining the material for the dental crown, individual factors such as the tooth's location and function, the position of the gum tissue, the amount of teeth visible when smiling, and the color of the surrounding teeth are evaluated.
Over time, teeth can become misshapen or damaged due to decay, injury, or usage. A dental crown is placed over the tooth to cover its visible part. Crowns, which protect teeth from fractures, are an effective method for restoring lost aesthetic appearance and function.
What are the Types of Dental Crowns?
There are different types of dental crowns, including gold, porcelain, porcelain-fused-to-metal (PFM), zirconium, and E-Max (Lithium Disilicate).
Gold Crowns: Gold dental crowns, which are combinations of other metals such as copper, nickel, or chromium, are highly durable and strong. However, they are rarely preferred today due to aesthetic reasons.
Porcelain Crowns: This is the most commonly used type of crown today. Made entirely of porcelain, these crowns provide the best and most natural appearance. They match surrounding teeth in shape, size, and color. Porcelain crowns are biocompatible and are considered the best option for anterior tooth restorations. They are non-toxic as they do not contain metal. However, for porcelain crowns to last a long time, proper maintenance is essential.
