Zirconium Crowns

Zirconium Crowns: Extremely Robust and Durable

Zirconium Oxide ZiO2 like Zeno, Cercon, Lawa, Everest or Cerec.

There is an obvious international trend to metal-free solutions. Disorders caused by allergic reactions, and also the insights of holistic medicine, necessitate the use of non-allergenic restorations. The old prejudice that ceramics show inadequate strength values, and therefore poor durability, is no longer justifiable, as the brand new CAD/CAM technology has been introduced.

Those industrially produced framework ceramics that are available today even exceed metals in  certain physical properties. One of the most important ceramic materials - zirconium oxide - 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 biocompatibility.

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 high strength, toughness and excellent long-term stability is reasoned by this transformation reinforcement.

Advantages of All-Ceramic Restorations:

• 100% metal-free, biocompatible, all-ceramic zirconium oxide restorations.
• Dentists do not have to readjust to a new technique.
• Excellent physical and mechanical properties. Zirconium oxide surpasses e.g. the still-widespread aluminium oxide ceramics in every aspect. Hence, even long-span posterior bridge frameworks are possible. In terms of aesthetics and biocompatibility, all-ceramic restorations have indisputable advantages, e.g.:
  • No interactions with other dental materials.
  • Insulating behaviour 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
