BruxZir^®

“More Brawn Than Beauty”

BruxZir® Total Zirconia Crowns are a new option for posterior restorations. With these virtually unbreakable all-ceramic crowns, you can provide your patients the strength to withstand severe parafunctional activity and avoid metal restorations. BruxZir is a full contoured zirconia crown or bridge with no porcelain overlay. It is glazed with a smooth surface but designed specifically for the posterior with more emphasis on brawn than beauty.

Benefits of BruxZir

• Ideal for bruxers & grinders who have destroyed other restorations.
• An esthetic alternative to posterior PFMs with metal occlusals and full-cast crowns.
• Made with biocompatible medical-grade zirconia.
• Monolithic material makes the restoration completely chip-proof.
• Fabricated using CAD/CAM technology for consistent fit.

Cementing Recommendations

• Resin reinforced glass ionomer cement
• Resin cements for short or over-tapered preparations (Unicem, 3M ESPE)

Prep Requirements

• Shoulder preparation not needed, feather edge is okay.
• It is a conservative preparation similar to full cast gold preps.
• 1.0 mm of occlusal space is ideal, however a prep with at least 0.5 mm is acceptable.

Adjustment and Polishing

• Use a fine grit diamond with water and air spray to keep the restoration cool and to avoid micro-fractures.
• If using air only, the lightest touch possible to achieve result
• Football shaped bur for occlusal and lingual of anterior teeth
• Tapered bur for buccal and lingual surfaces
• Always polish post-adjustment with porcelain polishing system
• Recommended: Axis BruxZir Adjustment and Polishing Set LS-7579-available from your dealer.

Removing a BruxZir Crown

• Any shape fine grit diamond will work. Zircut diamonds (included in the Axis BruxZir Kit)
• Use plenty of water. Firm pressure applied in repeated, short, on-off sequence.
• Cut through the crown facial to lingual and use crown spreader. Pieces normally come off in large chunks.
