Zirconium Oxide ZÝO2 like Zeno, Cercon, Everest or Cerec.
Extremely Robust and Durable
There is a clear international trend to metal-free soutions.Disorders
caused by allergic reactions,and also the insights of holistic
medicine , necessitate the use of non allergic restorations.
The old prejudice “ceramics show inadequate strength values”, and
therefore poor durability, is no longer justifiable ,due to the use of
CADCAM technology.The industrially produced framework ceramics
available today exceed metals in physical properties.
Zirconium oxide ,one of the most important ceramic materials, hasbeen
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
occuring in cracks is transformed into compressive stres, which
counteracts the crack and cannot expand any further.this is referred
to as “self-healing”. The transformatýon reinforcement is the reason
for high strength, toughness and excellent long-term stability.
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 stil-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
