Ultimate Dental Lab’s BruxZir® restorations provide superior esthetics than its PFM or full cast alternatives. With the extreme beauty of porcelain layered over an exceptionally strong zirconia base, this solution will provide your patients with the durability and esthetics they need. The translucent ziconia substructure provide lifelikes beauty that is not marred by the discoloration and black line along the gingiva that often accompanies metal-based restorations.

Indications

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.

Contraindications

Contraindications include: 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.

Preparation

Shoulder preparation not needed. A mild chamfer or a feather edge margin is good. 1mm buccal, lingual and occlusal reduction is ideal but can go to a minimum .5mm in some areas, when the 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 an ideal choice for buccal and lingual surfaces. Polish BruxZir zirconia restorations with the porcelain polishing system of your choice.

Cementation

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.

Tech Notes

Solid zirconia requires a cast gold type preparation. If adjustments are needed, use zirconia specific diamonds and rubber wheels polishing with diamond paste.
