BruxZir

Perfect Smile is BruxZir authorized dental lab. BruxZir is backed by our 5 year guarantee. More brawn than beauty, you’ll be impressed by the esthetics of BruxZir when prescribed instead of posterior metal occlusal PFMs and full-cast metal restorations. BruxZir is virtually chip proof, making it the ideal restoration for patients with BruxZir implant restorations and areas with limited occlusal space. BruxZir crowns & bridges are made from high quality Zirconia powder. Milling blanks are then created through a unique patent-pending process. Unlike conventional high-pressure milling blank manufacture, the processing gives BruxZir improved light transmission, which provides a lower, more natural shade value.

Designed and milled using CAD/CAM technology, BruxZir is sintered for 6.5 hours at 1,530 degrees Celsius. The final BruxZir restoration emerges nearly bulletproof and is glazed to a smooth surface.

STRENGTH: 1100 MPa

PATIENT BENEFITS:

  • Chip-resistant, as it is made of solid Zirconia with no porcelain overlay

  • Glazed to a smooth surface to reduce plaque accumulation


PREPARATION:

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.

CEMENTATION:

Advanced Z16™ 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.
