Zirconia is a metal classified as a member of the titanium family and is mined around the world. It is found in dinnerware and electrical fixtures among other products. It's known for its durability, making it an ideal product to use in dental crowns, especially posterior crowns that require a lot of strength for chewing and grinding food
Crowns made of zirconia are becoming increasingly common, and they do offer some advantages.
One of the biggest advantages of zirconia is its strength and durability. Consider how much force your back teeth exert on the food that you chew.
Your crowns need to be made of a strong material, so zirconia may be a good choice for crowns in the back of your mouth. Also, because zirconia is so strong, a dentist won’t have to do as much preparation of your tooth.
Zirconia is the choice of many dentists for its biocompatibility, which means it’s less likely to provoke the body into producing a reaction or immunological response like inflammation.
Another benefit to zirconia crowns is that dentists can make them in their office. Because zirconia crowns are milled directly from solid blocks of zirconia, they require less equipment, time, and materials to produce than other types of crowns, such as composite ceramic (porcelain and other ceramic material fused to a metal base). Dentists, therefore, can make them in-house without having to order the crowns from a dental lab. It is even possible for dentists to create and fit zirconia crowns in a single day.
