    “More Brawn Than Beauty”

    BruxZir® Solid 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.

    Seating Recommendations

    Recent research has shown that saliva contamination can hinder the bonding of solid zirconia and zirconia oxide copings. To successfully remove saliva, it is now suggested that after try-in and before priming, the crown should be cleaned with Ivoclean, a zirconia oxide solution from Ivoclar.

    The suggested protocol is:

    1. Try in BruxZir or zirconia-based restoration.
    2. Rinse saliva out of restoration with water.
    3. Place Ivoclean in restoration for 20 seconds, rinse and dry.
    4. Apply Primer and then cement with product of your choice.

    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.
