Zirconium restorations

Picture
Today zirconium - the material which is well known for years in other industrial fields - is commonly used in dentistry. There are different manufacturing methods as manual as CAD/CAM. We at Egressy Dental use the modern computerized CAD/CAM manufacturing technology. To learn more about our CAD/CAM system, click here!

Zirconium restorations meet the highest aesthetic and functional expectations and are biocompatible. They do not have a metal core therefore the adjoining gum will show no dark metal edges.
 Ceramic material is color- fast and wear-resistant. In addition, the low heat conduction protects the dental nerve, which is very sensitive to temperature changes. With less transparent types you can easily hide a metal post and core or an implant abutment. To learn more about zirconium click here!
3Shape’s design software and Wieland’s Zeno Star blanks are used during the manufacture.

Most common use of zirconium in dentistry:

  • As substructure of crowns and bridges
The caps are coated with layered ceramics.
  • Anatomic full zirconium crowns
The CAD/CAM system we use is able to manufacture  full zirconium crowns with the final anatomic form. There is no further porcelain veneering needed. Colors and shades are a result of painting. Advantages are: homogeneous structure, heavy duty and the resistance to chipping is at least four times higher than that of porcelain veneered zirconium.
  • Personalized implant abutments
Besides titanium abutments there are more and more laboratory fabricated zirconium implant abutments with individual design. As zirconium has a lot of favorable properties it is especially recommended in implant restorations. With computer aided design we are able to determine and shape the perfect harmony of height, angulation, and gingival situation.
  • Primer Telescopic crowns
The conventional way of primer and secunder production is gold cast but  a more precise and cost effective way –taking the current price of gold into account- is a CAD/CAM zirconium primer combined with  an electroplated gold secunder crown. Zirconium primers are milled and polished in a hydro-cooled milling machine.
