Zirlux®

Zirlux®

Our Zirlux® restorations are available in crown and bridge variations. Utilizing a solid zirconia substructure takes advantage of the reliability and exceptional strength of this material. Unlike metal restorations, zirconia does not negatively effect the porcelain layering, which allows for heightened beauty and esthetics. Zirlux is an excellent restorative option for patients who are looking for an alternative to metal restorations and want an end result that blends in with their natural dentition.

SEND A CASE

Indications

Zirlux FC2 zirconia is very versatile. It is indicated for copings, multi-unit frameworks, multi-unit bridges, inlays, onlays, full-contour crowns, full-contour bridges, implant abutments, and full arch/hybrid bridges. It is 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 .5mm in some areas, when the reduction is limited. Minimum occlusal reduction of 0.5 mm; 1 mm is ideal. Adjustments and polishing: Adjust Zirlux FC2 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 Zirlux FC2 zirconia restorations with the porcelain polishing system of your choice.

Cementation

Before cementing any Zirlux® FC2 restorations, the interior surface of the crown must be cleaned with Ivoclean (Ivoclar Vivadent; Amherst N.Y.); this is critical in assuring maximum bonding strength. These restorations may be cemented using conventional cement and luting materials. In order to optimize esthetics, it is recommended to use resin-modified glass ionomers and resin cement, instead of zinc oxide phosphate cement. When a greater bond is needed due to the lack of a retentive preparation, use resin cement like Relyx Unicam or Relyx Ultimate.

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.

BruxZir®

BruxZir®

BruxZir® is a restoration that is esthetically superior to PFM or full-cast restorations. With the extreme beauty of porcelain layered over the strong zirconia base, this solution will give your patients the durability and esthetics they need.

SEND A CASE

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.

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.

Full-Contour Zirconia

Full-Contour Zirconia

Our full-contour zirconia crown and bridge restorations do not contain metal and are 100% biocompatible. These restorations have the highest flexural strength of any all-ceramic option and are also extremely gentle on opposing dentition.

Indications

Full-contour 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.
