Zirconia Crowns are one of the popular dental crowns made from zirconium dioxide. Zirconium dioxide is a very durable metal even though it is categorized as a type of ceramic crown. Zirconium is a chemical element widely known for its hardness, resistance to corrosion, and various other properties similar to steel. Zirconia is mostly used because of its biocompatibility, high fracture toughness, and radiopacity nature. Dentists who wish to provide patients with excellent dental restorations will definitely choose Zirconia Crowns.
MAJOR ADVANTAGES OF ZIRCONIA CROWNS
- STRENGTH
Zirconia is preferred by many dentists for its strength. Zirconia is the strongest crown. It is extraordinarily tough. Since our back teeth exerts force on the food we chew, crowns need to be made of a strong material. So, it is a good choice to opt for crowns in the back of the mouth. Also, these crowns last longer than other types of crowns. It can withstand wear and tear very well. If you maintain it well, it can stay in your mouth for a long time. It has a very high flexural strength.
- BIOCOMPATIBILITY
Advantages of zirconia include its biocompatibility. This means, there are lower chances of infections, complications, pain, discomfort, and allergic reactions. No zirconia crown allergy has been reported yet and it is 100% biocompatible. Many studies showed that there are no adverse tissue reactions with fibroblasts and blood cells. This reflects zirconia’s appropriate beneficial cellular or tissue response optimizing its clinically relevant performance.
- ONE DAY PROCEDURE
Rather than sending an impression of your tooth to a dental lab, dentists can make Zirconia crowns in their offices. Also, they can cement the crown into your mouth in a single visit. From a block of zirconia, a dentist uses a dental milling machine to make the crown. ANd no need for 2 visits for this procedure.
- AESTHETICS
Zirconia Crowns provides a superior look to the users. They are visually almost impossible to distinguish from adjacent, real teeth, they have a colour and transparency as close as possible to natural tooth enamel. It has the ability to apply several layers and mix colours which gives the tooth maximum naturalness. Transformations to any shade which matches the rest of your teeth is possible.
- DURABILITY
Among various other crowns, Zirconium Crowns are the most durable material that can be used for crowns. If you are properly giving care, you will not have to change the crown in the next 15-20 years. Zirconium is said to be five times as strong as porcelain. Zirconium is also highly resistant to extreme hot and cold temperatures. And therefore, it lowers the frequency of tooth hypersensitivity. Crowns made of zirconia, called monolithic zirconia crowns, are especially durable to a greater extent.
MAJOR ADVANTAGES OF ZIRCONIA CROWNS
Many researches proved that Zirconia Crowns have minimal disadvantages. Among them, one is its opaque appearance which makes it look less than natural. Therefore, it is hard to match with the existing teeth. The other demerit is that it makes a potential wear on other teeth. Due to the hardness of the Zirconia could cause wear and tear on opposing teeth. Only bone-white substructures could be used to produce zirconia crowns initially. This could sometimes create problems in achieving an aesthetically perfect appearance. The abrasive quality of this material can cause friction against the root of the tooth as well as other teeth. You are bound to encounter extreme touchiness to cold and hot with all-porcelain crowns. Extraordinary temperatures can cause harm and break your tooth. In dentistry, Zirconia is used as structural material for dental bridges, crowns, inserts, and Dental implants.
CONCLUSION
Dental Crowns are caps used to cover a tooth or a dental implant. Zirconia Crown is one of the options available in dentistry. Zirconia crowns are becoming very common today. Mainly there are two main types of procedures for installing a dental crown. One is, your dentist can prepare your tooth and install a temporary crown during one visit and then cement the permanent crown into your mouth during the second visit. If the dentist has the appropriate equipment and technology to create a zirconia crown in-office then you can have the same-day procedure. In this process, the dentist will examine your mouth and will take digital pictures and prepare your tooth for the procedure. After that, they use a digital scan from the photos to create the crown in the office. At last, the dentist will cement the crown into place.
