Did you know?

• Crystal zirconium is used as a basis for metal-free crowns. It was discovered in 1789 by German chemist Martin Klaproth. This is one of the hardest materials and was primarily used in space technologies.
• Zirconium is biocompatible. Numerous studies have found that zirconium does not cause any adverse effect on the body.
• Refraction of light and transparency of zirconium are very similar to natural teeth. Well done zirconium crowns are almost indistinguishable from natural teeth.

The advantages of zirconium (metal-free) crowns

The basic dilemma you will meet you after the dentist recommends compensation of one or more teeth by dental crowns or prosthetic bridge is whether to choose metal or zirconium crowns (with us often called metal-free crowns).

All or almost all of the advantages are on the side of zirconium crowns, and some of the most important are:

• To install zirconium crowns up to five times less tooth substance must be removed.
• Complete biocompatibility of the material. Zirconium crowns are perfectly safe for general human health, while metal in metal dental crowns can produce irritation and allergic reactions to soft tissue or gum.
• They are more permanent
• Zirconium crowns are at least five times stronger than the metal ones. Even and after many years they will not change their physical and chemical properties. The exterior is not subject to change, while with the metal structures a gray line at the junction of crown and gum may eventually appear.
• Aesthetically superior to metal
