Crowns (caps)

Dental crowns, also known as dental caps, cover damaged or discoloured teeth. Its purpose is to strengthen or improve the appearance of a tooth. A crown is placed for a number of reasons:

• to support a large filling when there isn’t enough tooth remaining
• to attach a bridge
• to protect weak teeth from fracturing
• to restore fractured teeth
• to cover badly shaped or discoloured teeth
• to cover a dental implant

.

Types of Dental Crowns:

Porcelain crown

Ideal for single crowns, bridges. Dental crowns made of porcelain fused to metal are strong enough to anchor bridges as well. As the metal shell is fully covered with porcelain it improves the aestetic appearence.

All porcelain crowns

These type of crowns are made of porcelain and are metal–free. They create an extremely natural looking appearance and are typically used on front teeth but do not function on bridges.

Cercon crowns

This innovative system combines the durability of porcelain fused to metal bridges with the aesthetic appearance of metal–free crowns. This system is based on the material zirconium-oxide (cercon).

What is zirconium oxide?

Nowadays we can hear more and more about the probable allergic effects of metals applied in dentistry. Therefore the use of a material having the same good mechanical properties as metals but doesn't affect allergic reactions in human organism became necessary. While zirconium oxide does not have any allergic effects described in scientific publications, this material can be told as "biocompatible". It appertains to his good qualities that it conducts heat very badly, so the patients do not complain about cold or heat sensitiveness. This material is produced with the help of the most modern CAD/CAM computer technologies. Zirconium oxide crowns and bridges are the most aesthetic solutions.

The traditional crowns have a porcelain layer burnt on a metal cap, so its light permeability is weak. The light permeability of porcelain crowns burnt on zirconium oxide look like the own natural teeth. Because there aren't any metal caps, the dark metal frame-edge of the crown will not be visible if the gums may draw back in after years.
