Zirlux® 16+

Zirlux® 16+

An ideal alternative to porcelain and PFM restorations, Zirlux® 16+ offers high translucency, consistent shading, and 800 MPa strength. Patients choose Zirlux 16+ because it’s a strong, highly esthetic alternative to metal that provides them with the esthetics and functionality they demand. Designed and milled to R-Dent’s exacting precision on one of the industry’s most advanced digital workflows, Zirlux® 16+ won’t chip or crack, and is gentle on opposing dentition.

Additional Information

In addition, achieve the color and consistency you demand with preshaded discs. Masterfully designed and fabricated by R-Dent’s expert CAD/CAM technicians, Zirlux 16+ offers improved esthetics for durable restorations. Discs available in white or preshaded discs to match all 16 Vita® Classical shades and three bleach shades, allowing predictable shading for every case.

Dip Shaded Zirconia Comparisons

Other zirconias use “dip color” which only penetrates about 1 to 1.5 mm. When making clinical adjustments, if you go beyond 1 to 1.5 mm with dipped coatings, you will hit the white core, creating light spots.

Why I Invested – Consistency & Super Translucency

We have always observed strong results from Zahn Dental’s Zirlux FC2 zirconia, so we were excited to switch recently to the new Zirlux 16+ pre-shaded discs. In trials, we observed time savings and an improved workflow. In a competitive market, anything we can do to standardize our process is important.

Key Features

  • High translucency for increased esthetics
  • Preshaded discs for consistent coloration
  • Suitable for supra gingival and feather edge margins
  • Pre-shaded material produces consistent and predictable restorations
  • Esthetic alternative to metal
  • Low wear to opposing enamel

Benifits of Zirlux® 16+

  • High Strength =1100 MPa flexural strength
  • Conservative preparations: 0.5 mm minimum thickness
  • High translucency: increased esthetics
  • Easily polished: provides low enamel wear
  • Color throughout — No White Spots!
  • Made in the USA


Zirlux FC2 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 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 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 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 the ideal choice for buccal and lingual surfaces.
Polish Zirlux FC2 zirconia restorations with the porcelain polishing system of your choice.


Zirlux FC2 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 Zirlux FC2 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.

“I have confidently placed hundreds of Bruxzir crowns and it was revolutionary for its time. When Zirlux came along, I found equal accuracy and cost to Bruxzir but with much better shade esthetics. I can now place full-contour zirconia using Zirlux on cuspids and premolars. Zirlux has greatly simplified my restorative requirements.”
