Milled from solid zirconia, BruxZir® 16 restorations resist chipping and fracturing associated with layered porcelain restorations. Because of its strength as well as natural translucency, BruxZir 16 performs equally well as posterior or anterior restoration, and can be milled as a single unit or a full bridge.
Because coloration is added during fabrication of the disc, BruxZir 16 provides consistent shading, even after adjustment. Available in all 16 Vita ® Classical Shades for a full range of coloration, BruxZir 16 makes reliable shade-matching simple.
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 BruxZir® 16 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 BruxZir® 16 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 Zirconia restorations are glazed to a smooth surface to reduce plaque accumulation.
