It is crucial to keep a minimum wall thickness* for a successful restoration, and keep in mind:

*Not including the thickness of build-up porcelain

Mimimum Wall Thickness of Zirconia

  • Anteritor crown
  • Posterior crown
  • Veneer*
  • Onlay
  • Inlay
  1. The thickness specifications apply to full zirconia restorations. The thickness of build-up porcelain is not included.
  2. The minimum wall thicknesses apply to full zirconia restoration or to frame-work for build-up porcelain restoration. In these cases, 0.4 mm (anterior) or 0.5 mm (posterior) should be kept for the area located in the bottom (lower) half of the disc.
  3. If full zirconia veneer restoration is used for combination with the porcelain, 0.8 mm or more should be kept for the area located in the upper half of the disc.
  • Anteritor crown
  • Posterior crown
  • Veneer*
  • Onlay
  • Inlay

*Keep 0.8mm in case of porcelain build-up. You can reduce to 0.4mm when finishing with glaze and polish.
