Zirconium Crowns
Extremely Robust and Durable.
Zirkonium Oxide ZrO2 like Zeno, Cercon, Lawa, Everest or Cerec
Metal alloys, except titanium, used in dentistry may induce allergic reactions. Not to mention that different metals present in the mouth generates undesirable galvanic currents that may cause serious oral mucus membrane disease. Instead of amalgamate fillings, aesthetic fillings prepared by adhesive techniques are more popular, while instead of metal-base porcelain dentures, zirconium-oxide frame porcelain dentures appeared on the market making implants made of zirconium-oxide available.
It seems that metal-free dentures will soon sweep metal-base porcelain prosthesis out from practice. Besides correct oral hygiene and prevention, the application of extra hard ceramics systems will create a long lasting health of your teeth.
Zirconium-base ceramics are about three-times more expensive than metal-ceramics and full porcelain dentures however, this can provide the longest chewing capability and preservation of aesthetics of teeth.
Zirconium oxide, one of the most important ceramic materials, has been used for artificial hip or knee joints in human medicine for many years. In this field of application, the material has really proven its worth, thanks to its extreme durability and excellent bio-compatibility.
Zirconium oxide has a crack-inhibiting structure. The tensile load occurring in cracks is transformed into compressive stress, which counteracts the crack and cannot expand any further. This is referred to as "self-healing". The transformation reinforcement is the reason for high strength, toughness and excellent long-term stability.
Advantages of All-Ceramic Restorations
Zirconium crowns: 100% metal-free, bio-compatible, all-ceramic zirconium oxide restorations
Dentists do not have to readjust to a new technique.
Excellent physical and mechanical properties. Zirconium oxide surpasses for example the still-widespread aluminum oxide ceramics in every aspect. Hence, even long-span posterior bridge frameworks are possible. In terms of aesthetics and bio-compatibility, all-ceramic restorations have indisputable advantages, such as:
- no interactions with other dental materials,
- insulating behavior with regard to cold and heat stimuli,
- nearly perfect imitation of natural teeth,
- no discoloration along the gumline,
Applications
- For high-allergy-risk patients
- Wide-span bridges
- Suprastructures on implants
- For high aesthetic demands
