Zirconia Ceramics For Crown Implants Application

The cermet fixed partial denture (FPD) is considered to be the gold standard and is a reliable material. However, the requirements of aesthetic dentistry and the biocompatibility of dental alloys have become increasingly prominent, supporting the commercialization of new products.

Today, all-ceramic prostheses are replacing more and more metal restorations. Various ceramic systems have been developed for the single crown or fixed dentures (FDP) with excellent aesthetics.

Traditional ceramics (glass fiber reinforced and feldspar ceramics) and Al2O3 reinforced ceramics have encountered some problems, especially in the molar area. The ceramic materials used, core veneer bond strength and crown thickness are some of the factors necessary to resist bite forces. The reliability of industrial prefabricated ceramic blocks seems to be more consistent than laboratory manual processing of ceramics.

Compared to other all-ceramic systems, converted toughened zirconia ceramics is a good alternative in different clinical situations. The following advantages of zirconia ceramics explain why zirconia crowns are becoming more popular.

Biocompatibility.

Since the body does not reject zirconium, it reduces the likelihood of infections, complications, pain, discomfort and allergic reactions to the crown.

Great at hiding tooth damage.

Zirconium is preferred over porcelain in covering up and hiding tooth damage caused by staining or fractures.

Durability.

Being made of quartz, zirconium is hardly destroyed and can withstand the most violent spikes and bites. In fact, the strength of zirconium is five times that of ordinary ceramics. The zirconium crown is hardly destroyed by crushing. They also resist extreme temperatures and temperatures and reduce the frequency of tooth allergies.

Long-lasting.

Going along with its durability, zirconium crowns also last longer than porcelain crowns. This is, mainly due to zirconium being more resistant to chipping and cracking.

Can be easily modified, reshaped and colored.

Although the structure of zirconium is strong, zirconium crowns can be easily molded, sized and colored to match the patient’s natural teeth. It is believed that the ductility of the zirconium crown can produce a crown of a better shape than its original crown. The ability to create perfect shapes, sizes and colors give patients a more natural and natural look.

Less tooth structure has to be removed.

Typically, when a crown is needed, a layer of the original tooth is removed for the crown to fit over it properly. The strength of zirconium means that a thinner layer of it is required for the crown. A thinner crown results in less of the original tooth to be removed.

Aesthetically pleasing.

Zirconium crowns are translucent being made from crystal. The clear, translucent appearance of zirconium allows for the perfect tooth coloring that best matches the patient’s natural tooth color, better than gold or porcelain crowns.

No metal is needed.

Unlike gold or porcelain crowns, zirconium crowns don’t require to be fused with a metal base which make traditional crowns more noticeable.
