BruxZir Clinical Indications & Scientific Validation

BruxZir Solid Zirconia clinical indications continue to expand as science validates the benefits of this proprietary material. In a new clinical DVD, “BruxZir Solid Zirconia Crowns & Bridges Clinical Indications and Scientific Validation,” Dr. Michael DiTolla shares two anterior crown cases and a BruxZir roundhouse bridge case. See for yourself why this unique material continues to gain popularity with dentists and laboratories alike.

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.)
