All-ceramic crowns

Zirconia crowns - no dark line at the gum.

About this service

Zirconium oxide crowns solve the main problem of classic metal-ceramic: no dark line revealed at the gum after years. Stable colour, near-natural light transmission, strong enough for posterior teeth and larger bridges. No allergic reactions - biocompatible material.

Step by step

How the procedure works

  1. Examination, X-ray and shade selection.
  2. Tooth preparation under local anaesthesia.
  3. Digital impression.
  4. Milling of the zirconia substructure in our CAD-CAM lab.
  5. Sintering in a furnace to over 1300 MPa.
  6. Veneering porcelain layering and final shade work.
  7. Try-in and cementation.

When it is needed

Materials & technology

Zirkonzahn Prettau zirconium oxide - premium class, documented clinical success over 15 years.

Frequently asked questions

Does zirconia look glassy?
No. Modern zirconia (Prettau) has good light transmission and looks like a natural tooth.
Is there a warranty?
Yes, written - typically 10 years for premium zirconia.
Is the dark line gone forever?
Yes. No metal - no line. The crown looks natural even if the gums slightly recede over time.
