03-bruxzir
BruxZir®

We offer both BruxZir® and a Full Contour Zirconia.

Unmatched for its strength, BruxZir® solid zirconia is the right choice for bruxing patients.

Our FCZ has improved esthetic incisal blend for enhanced shade characteristics. With our shaded crowns, minor adjustments can be made without the white core shining through.

Using advancements like dynamic articulation and automatic contact strength adjustment, your crown will fit. Final seats should need little to no adjustment.

Authentic Bruxir Laboratory

Indications

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

Preparation

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 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 restorations with the porcelain polishing system of your choice.

Cementation

  • 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)

Tech Notes

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.
