Layered Zirconia

The Great State technicians want to help you provide the best restorative option for every case. Our full-contour zirconia crowns and bridges are crafted out of the highest quality zirconia to ensure superior esthetics and fit. Full-contour zirconia is the all-ceramic option that offers the highest flexural strength paired with lifelike translucency and esthetics. Our team uses the latest digital dentistry to ensure superior fit and smooth surfaces. This option is a great solution even for patients who experience nighttime bruxism. You can be confident in prescribing our full-contour zirconia crowns and bridges due to its fracture-resistance and superior features.

Features:

  • Hypoallergenic
  • Biocompatible
  • Highly Esthetic Results
  • Translucent Porcelain

A zirconia coping provides full-contour strength, while a cosmetic layer of porcelain provides the translucency of traditional PFM. Because of zirconia’s shading and reflective properties, zirnonia restorations’ translucency surpasses that of conventional PFM. With zirconia’s natural coloration, the coping won’t be visible at the margin if gingiva recedes.

When esthetic expectations are high and it is important that the restorations match surrounding natural dentition or other existing restorations. If bonding is necessary to retain the restoration, bond strength is weaker and less predictable than other ceramics.
Shoulder preparation not needed. A mild chamfer or a feather-edge margin is good. 1mm buccal, lingual, and occlusal reduction is ideal, but can go to .5mm in some areas when reduction is limited. Minimum occlusal reduction of 0.5 mm; 1 mm is ideal. Adjustments and polishing: Adjust full-contour zirconia crowns and bridges using water and air spray to keep the restoration cool and to avoid microfractures with a fine grit diamond. If using air only, use the lightest touch possible when making adjustments. A football-shaped bur is the most effective for occlusal and lingual surfaces (on anterior teeth); a tapered bur is the ideal choice for buccal and lingual surfaces. Polish full-contour zirconia restorations with the porcelain polishing system of your choice.

Full-contour zirconia may be cemented using a resin reinforced glass ionomer such as RelyX Luting cement. When a greater bond is needed do to the lack of a retentive preparation, use resin cement like RelyX Unicam or RelyX Ultimate. Before cementing all full-contour zirconia crowns, the interior surface of the crown needs to be cleaned with Ivoclean (Ivoclar Vivadent – Amherst, NY). This is critical in assuring maximum bond strength.

Solid zirconia requires a cast gold type preparation. If adjustments are needed, use zirconia specific diamonds and rubber wheels polishing with diamond paste.
