Designed and milled using CAD/CAM technology, BruxZir® Solid Zirconia is a monolithic solid zirconia restoration with no porcelain overlay. BruxZir® is an esthetic alternative to PFM metal occlusal/lingual or full-cast restorations. The chip resistant durability of BruxZir® is ideal for bruxers, implant restorations and areas with limited occlusal space. BruxZir® Solid Zirconia is indicated for crowns, bridges, implants, inlays and onlays.
BruxZir zirconia is so versatile, it can be used in almost any situation from singles, bridges with any combination of abutments and pontics, inlay bridges, Maryland type bridges and screw retained implants. Also an esthetic alternative to a PFM with metal occlusion due to limited space.
When esthetic expectations are high and it is important that the restorations match surrounding natural dentition or other existing restorations
If bonding is necessary to retain the restoration, bond strength is weaker and less predictable than other ceramics
Shoulder preparation not needed. A mild champfer or a feather edge margin is good. 1mm buccal, lingual and occlusal reduction is ideal, but can go to .5mm in some areas, when reduction is limited.
Minimum occlusal reduction of 0.5 mm; 1 mm is ideal.
Adjustments 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 zirconia restorations with the porcelain polishing system of your choice.
BruxZir zirconia may be cemented using a resin reinforced glass ionomer such as Relyx Luting cement. When a greater bond is needed do to the lack of a retentive preparation, use resin cement like Relyx Unicam or Relyx Ultimate.
Before cementing all BruxZir zirconia crowns, the interior surface of the crown needs to be cleaned with Ivoclean (Ivoclar Vivadent; Amherst N.Y.). This is critical in assuring maximum bond strength.
Solid zirconia requires a cast gold type preparation. If adjustments are needed, use zirconia specific diamonds and rubber wheels polishing with diamond paste.
