Zirconium-oxide

The zirconium-oxide is metal-free, so it is anti-allergic. It meets the stricktest requirements of implantology. Since the reactions of the soft tissues to it are excellent, the gum remains healthy around the crowns and bridges.

The Zirconium is essentially a variety of ceramic, but it is much stronger and less fragile. While the tensile strength of the traditional porcelain crowns are 120 – 190 Mpa, then the zirconium-oxid crowns more then 1200Mpa, so we receive an extremely chargeable surface. 

 (The dental enamel tensile strength is circa 200 Mpa ). Thanks to this new ceramic material (cercon), all-porcelain replacements can be made extremely stable and esthetically outstanding. All-porcelain restorations made of Cercon can last for decades as proven by 10 year clinical experience.

The strong but grey metal framework of traditional metal ceramic crowns raised many problems: 

increasing number of metal allergy cases insufficient aesthetic end result: the metal frame of  traditional metal ceramic crowns does not let light  through, therefore the transparency of these crowns  differs from that of natural teeth.

To solve the above mentioned problems, zirconium dioxide based frames have been developed. A frame was necessary which is strong as a metal one but does not have the colour of metal, nor is made of it.
Zirconium is an esthetic and tissue-friendly solution. It has been used for 20 years in medicine since it is well tolerated by the human body. The zirconium-oxide based crowns are the latest innovation of modern aesthetic dentistry.

About the zirconium dioxide crown:

the zirconium – dioxide frame is strong, even stronger than traditional metal frames, therefore provides a strong hold it does not contain metal nor is coloured metal: the frame itself is already white or tooth coloured the covering ceramic provides perfect aesthetic effect on a tooth coloured frame

• does not let light through, so it is perfectly suitable for covering grey teeth

• this is the only metal-free type of crown that is suitable not only for solo crowns, but also for preparing longer bridges to replace several gaps

Encarving zirconium-oxide frames does not happen with traditional methods. With the so-called CAD/CAM computer technique, extremely precise frames can be manufactured
