What is a CEREC Crown Made of?
CEREC crowns are available in porcelain, zirconia, resin, and composite materials, however, porcelain and zirconia are the most common. Continue reading to learn more about each type and how to determine which one is best for you.
A porcelain crown of this type can sustain up to 450 pounds of stress per square inch, making it extremely durable. Because the human mouth can only chew with about 250 pounds of force per square inch, a porcelain crown should have few, if any, problems with natural wear and tear. Depending on care and upkeep, this type of crown can last anywhere from 5 to 15 years. Many patients prefer porcelain crowns for teeth because they look so natural. It can easily be blended in with the color of the surrounding teeth, making it virtually undetectable to others. It’s also stain-resistant and shouldn’t show signs of wear quickly. Porcelain reflects light effectively, giving it a lustrous sheen that should last for years. The crown will not cause gum irritation or an allergic reaction because it is made of a metal-free material. It is risk-free for everyone.
A zirconia crown can withstand a force of 850 pounds per square inch, making it an excellent choice for individuals who grind or clench their teeth. Even with the more intensive wear that a zirconia crown can withstand, it can last 10-15 years or more. Zirconia has also a more opaque appearance than porcelain, making it less natural and more difficult to match to the surrounding teeth. This is another reason why this style of crown is usually saved for the back teeth, which are less apparent.
The CEREC crown, whether made of porcelain or zirconia, should appear and feel natural and last for many years. It should also have no adverse effects on the tongue or gums. ore in detail Visit our Bellevue office and talk with our specialists about materials for your particular situation!
