When it comes to restoring a patient’s smile with dental crowns, more and more dentists are opting for zirconia over a traditional porcelain-fused-to-metal. Many dentists are making the switch because of the purported benefits of using zirconia over other options, like its additional strength, durability, and aesthetic appeal.

Zirconia Crowns: WHAT

Zirconia restorations are made from Zirconia dioxide, a metal oxide. The incredible strength of monolithic Zirconia used for dental restorations comes from its tetragonal crystalline properties. The all-ceramic material doesn’t require any unsightly metal substructure for stability, is resistant to wear, and difficult to crack.

The three types of zirconia used in dental crowns are:

• Solid or monolithic zirconia

• Layered zirconia

• High translucent zirconia

Each type of zirconia has its own specific benefits and is on the practitioner’s choice to determine the best material for each case.

Zirconia Crowns: WHERE

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 the best choice for crowns in the back of your mouth. Also, because zirconia is so strong, we can also perform zirconia bridges with excellent physical and esthetic properties.

So, wherever strength is the issue at stake, zirconia is the answer.

The natural opaque shades of zirconia may in some instances work as an advantage especially when we have to restore dark, discolored teeth.

Zirconia Crowns: WHEN

Zirconia crowns are the best choice when we want to restore a severe damaged tooth in the posterior area of the mouth.

 Also zirconia bridges can replace successfully, the all time classic, porcelain fused to metal bridges due to its strength and biocompatibility.
