Indicated for posterior crowns, bridges, inlays and onlays. An esthetic solution for bruxers and grinders when PFM metal occlusal/lingual or full-cast restorations are not desired or when patient lacks the preparation space for a PFM or has broken a PFM in the past. Zirconia can also be used for anterior teeth with a facial veneer of porcelain for improved esthetics

Shoulder preparation not needed, feather edge is okay. It is a conservative preparation similar to full-cast gold, so any preparation with at least 0.5 mm of occlusal space is accepted.

Minimum occlusal reduction of 0.5 mm; 1 mm is ideal.

Adjustments and polishing: Adjust Full Contour Zirconia zirconia crowns and bridges using water and air spray to keep the restoration cool and to avoid micro-fractures 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.

• Resin Ionomer cement (RelyX or RelyX Unicem, 3M ESPE)
• Maxcem Elite (Kerr)
• Panavia F 2.0 (Kuraray) -ideal for short, tapered preparations
• Glass ionomer cement (GC Fuji, GC America)

Solid zirconia requires a cast gold type preparation.

Anteriors may have a facial veneer of porcelain but the occlusion will remain in 100 percent zirconia. Final restorations are glazed to a smooth surface to reduce plaque accumulation.
