Precision Dental Designs brings you Zirlux® FC2, a full-contour zirconia for the modern age of dentistry. This CAD/CAM fabricated zirconia improves the original Zirlux system and provides outstanding vitality and esthetics. It is a perfect esthetic alternative to metal restorations and has a flexural strength greater than 1100 MPa. Not only will it exceed your patient’s expectations, but your own.
- All 16 VITA® Classic shades
- >1,100 MPa
- Low enamel wear
- Easily polished
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 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
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.
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.
Solid zirconia requires a cast gold type preparation. If adjustments are needed, use zirconia specific diamonds and rubber wheels polishing with diamond paste.
