BioZX2 High Strength Zirconia


BioZX2 is our newest formulation of high strength zirconia for both PFZ (porcelain fused to zirconia) layered crown and bridgework and FC (full contour) monolithic crown and bridgework. Each BioZX2 restoration is made from the highest quality zirconia that features increased translucency (due to its very high light transmission) for improved esthetics and vitality. Designed and milled using precision CAD/CAM technology, BioZX2 crowns and bridges are extremely strong and virtually chip-proof in their construction. Available in all of the 16 Vita shades, BioZX2’s glazed surface provides an outstanding low abrasion behavior, being less abrasive than traditional veneering ceramic. Smooth, biocompatible and plaque resistant, BioZX2 is the new generation, high performance alternative to a PFM.



BioZX2 PFZ (porcelain fused to zirconia)
BioZX2 can be milled as a highly translucent zirconia framework for individually hand-layered veneering with premium Noritake porcelain. Available as single crowns throughout the arch or as multi-unit bridgework up to a full roundhouse, BioZX2 PFZ’s are our recommended restoration for highly esthetic all-ceramic restorations for both conventional and implant applications.


BioZX2 FC (full contour monolithic)
BioZX2 FC, the newest full contoured zirconia restoration from DAL, features the many benefits of monolithic construction with no porcelain overlay. While BioZX2 FC is fabricated of 100% zirconia, you will be impressed with this new generation of translucent zirconia, the ideal replacement for metal occlusal PFM’s, full cast metal restorations and posterior PFM’s.


Screw-Retained BioZX2
A one-piece alternative to cemented implant restorations. This restoration combines the abutment and crown into one solid restoration.

Benefits for Your Patient

  • Greater translucency for improved esthetics
  • Chip-resistant, as it is made of full zirconia with no overlay porcelain
  • Glazed to a smooth surface to reduce plaque accumulation


  • Resin reinforced glass ionomer cement (RelyX Luting Cement, 3M ESPE; GCFuji Plus, GC America)
  • Resin cements for short or over-tapered preparations (RelyX Unicem, 3M ESPE; Panavia F2.0, Kuraray)

BioZX2 restorations are fabricated from solid zirconia oxide material, which exhibits a strong affinity for phosphate groups. We can take advantage of this fact with phosphate-containing primers such as Monobond Plus (Ivoclar Vivadent) and Z-Prime™ Plus (Bisco), or with cements such as Ceramir® Crown & Bridge (Doxa Dental) to increase our bond strengths to zirconia oxide. Unfortunately, saliva also contains phosphates in the form of phospholipids. When a BioZX2 crown or bridge is tried in the patient’s mouth and comes in contact with saliva, the phosphate groups in the saliva bind to the zirconia oxide and cannot be rinsed out with water. Attempting to use phosphoric acid (which is full of phosphate groups) to “clean out” the saliva only makes the problem worse.

The only way to successfully remove these phosphate groups from the interior of a BioZX2 restoration is with the use of Ivoclean (Ivoclar Vivadent). This zirconia oxide solution is placed inside the restoration for 20 seconds and then rinsed out. Due to the large concentration of free zirconia oxide in the Ivoclean, it acts as a sponge and binds to the phosphate groups that were previously bonded to the restoration. Once the Ivoclean is rinsed out, you will have a fresh bonding surface for the Monobond Plus, Z-Prime Plus or Ceramir to bond to.

Preparation Guidelines

Both the BioZX2 PFZ and the BioZX2 FC require a gentle, minimally invasive preparation with less loss of tooth structure. Shoulder preparation not required, feather edge is okay. It is a conservative preparation similar to full-cast gold so any preparation with at least 0.5 mm of occlusal space is accepted; however, 1.0 mm is ideal.
