Zirconia or Zirconium Oxide is the newest addition to the family of dental ceramics, it has been used extensively in medicine for hip replacements and in jewelry for mimicking of diamonds, in its medical capacity it has shown itself to be highly reliable in high stress situations.
If you are doing large reconsruction case we strongly recommend using our Smile Design Protocol to get the most predictable and reliable result.
Lava, Etkon which is best?
Our zirconia crowns use high density ytrium stabilised zirconia... exactly the same material as both Lava and Etkon. The only difference in these systems in our opinion is the manufacuring process of the framework. We use our own inhouse CADCAM milling system - Sirona inLab. We've found these frameworks to always be of the highest quality. Our zirconia resotrations are conventionally cemented, but please avoid polycarbxylate due to its excessive expansion.
How do we make our Dental Zirconia Crowns?
Many other zirconia systems rely on impersonal, factory style production techniques....NOT ours!
We use the latest CADCAM technology to mill our own frameworks whilst controlling our own quality, all in a shorter time frame.
If you have tried a Zirconia crown from another laboratory ask them these questions-
1. Do you use full CADCAM technology to get the best fit?
2. Do you design your own frameworks for the best ceramic support?
3. Do you mill your own frameworks for the best quality control?
If the answer to any of the above is NO then you need to try our zirconia crowns.
