Zirconia-based ceramic crown

What is the Zirconia-based ceramic crown?

Zirconia crown is made of a strong, biocompatible material, zirconia which is also used in medical applications like artificial joints. It is a well-known, type of all-ceramic crown which significantly improves the tooth appearance that has been previously disfigured or stained for years.

Different types of zirconium dental crowns include:
• glass-infiltrated zirconium toughened alumina (InCeram Zirconia);
• yttrium cation-doped tetragonal zirconia polycrystals (Cercon Zirconia);
• partially stabilized zirconium (Mg-PSZ);
• shrinkage free ZrSiO4 ceramic;
• Cercon Base ZrO2 sintered crown.

Advantages and disadvantages of Zirconia crown

Zirconia, also known as artificial diamond, is made of the highest-strength fine ceramic called zirconium oxide (ZrO2). A zirconia crown is strong enough and suitable for the restoration of back teeth. Main advantages of zirconia-base ceramic crown include:

• Strength. A zirconia crown is strong yet flexible. It can be used for back teeth as well as the front teeth.
• Long-lasting durability. Due to a fine crystal structure, zirconia is durable and resists wear for a long time.
• Aesthetic. Because a zirconia crown has a high-level of light transmittance, it is slightly transparent similar to a natural tooth. Also, it does not cause gum discoloration.
• Biocompatible. A zirconia crown is highly biocompatible because it is metal-free.

The zirconia crown is tough, durable and possesses abrasive quality thus imposing the friction against the tooth root including neighboring teeth. Hence, an E-max crown could be a favorable option for cases that require preservation of the root structure.
