Indications

BruxZir Solid Zirconia is indicated for crowns, bridges, implants, inlays and onlays, screw-retained implant crowns and full-arch implant prostheses. It is an esthetic alternative to PFM metal occlusal/lingual or full-cast restorations. The chip proof durability of a BruxZir restoration is ideal for bruxers who have broken natural teeth or previous PFM restorations. BruxZir Solid Zirconia is also ideal when the patient lacks the preparation space for a PFM.

Benefits for the Patient

  • Chip-resistant, as it is made of solid zirconia with no porcelain overlay
  • Glazed to a smooth surface to reduce plaque accumulation

Prep Requirements

  • 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.
  • For BruxZir Esthetic restorations, a minimum occlusal reduction of 0.7 mm; 1.25 mm is ideal.

Instructions for Adjusting 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. Or, purchase the BruxZir™ Polishing and Adjustment Kit through Glidewell Direct by visiting www.glidewelldirect.com or by calling 888-303-3975.

Recommended Cementation

  • Ceramir Crown & Bridge or a resin-reinforced glass ionomer cement such as RelyX™ Luting Cement (3M ESPE; St. Paul, Minn.) or GC Fuji Plus™ (GC America; Alsip; Ill.)
  • For short or over-tapered preparations, use a resin cement such as RelyX™ Unicem (3M ESPE) or Panavia™ F2.0 (Kuraray; New York, N.Y.)
