BruxZir Solid Zirconia - Crowns & Bridges - Dental Zirconia

Technical Information

BruxZir® Solid Zirconia is indicated for crowns, bridges, veneers, 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 and ideal for restorations requiring extra durability such as crowns under partials or screw-retained implant crowns. The chip-proof durability of BruxZir restorations also makes them ideal for bruxers who have broken natural teeth or previous PFM restorations. BruxZir restorations are also ideal for patients lacking the preparation space for a PFM.

BruxZir Anterior is the latest advancement in the BruxZir Solid Zirconia product line. This highly esthetic restorative material is designed specifically to satisfy the esthetic and functional requirements of the anterior region of the mouth. Exhibiting an average flexural strength of 650 MPa with translucency and color similar to natural dentition, BruxZir Anterior is an ideal, esthetic solution for your anterior cases. BruxZir Anterior restorations exceed the ISO strength requirements for cemented all-ceramic restorations and are ideal for anterior and premolar cases. Indications include single-unit crowns and bridges with one pontic.

Preparation Requirements for BruxZir Crowns & Bridges

Shoulder preparation not needed, feather edge is OK. 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 Anterior restorations, a minimum occlusal reduction of 0.8 mm; 1.25 mm is ideal.

Cementation Recommendations

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.)
