Zirconia Dental Crowns: Advantages and Disadvantages to Consider
Restoring a damaged tooth is crucial for maintaining a healthy smile. Among the various options available, zirconia dental crowns have gained popularity for their strength and natural appearance. But are they the right choice for you? In this guide, we'll explore the advantages and disadvantages of zirconia crowns to help you make an informed decision. Read on to discover whether a zirconia crown is the best option for your dental needs.
What Is a Zirconia Crown?
A zirconia crown is a type of dental crown made from zirconium dioxide, a durable and robust ceramic material. This dental restoration is known for its exceptional strength and durability, closely resembling natural teeth in appearance.
How Is a Zirconia Crown Made?
The crown is made from zirconia using advanced dental technology. A digital impression of your tooth is taken, and the crown is milled from a solid block of zirconia ceramic. This process ensures a precise fit and reduces the need for multiple dental visits.
Types of Dental Crowns: An Overview
Understanding the different types of dental crowns helps in comparing options:
- Metal Crowns: Made of gold or alloy; very strong but lack aesthetic appeal.
- Porcelain Crowns: Natural-looking but less durable.
- Porcelain Fused-to-Metal (PFM) Crowns: Metal base with a porcelain exterior; stronger than all-ceramic but may show metal edges over time.
- All-Ceramic Crowns: Metal-free and aesthetically pleasing.
- Zirconia Crowns: Combining the strength of metal crowns with the aesthetics of porcelain.
