The fascinating all-ceramic ingeniously combines esthetics with flexibility, and it accommodates all applications and fabrication techniques. Regardless of the type of restoration needed, whether it be an efficiently fabricated monolithic posterior crown, a stable bridge, an implant-supported restoration or a highly esthetic and elaborately customized single anterior tooth:

• Wide spectrum of applications, ranging from crowns to 14-unit bridges[1]

• Extensive fabrication possibilities: staining, cut-back, layering and infiltration

• The One-Disc Solution simplifies stock management in the laboratory

• Very high flexural strength (1200 MPa) in the dentin zone, where bridges have to withstand the strongest forces

• For restorations on natural prepared tooth structure or on approved implant systems[1]

• Ideal for complex cases involving gingival recession or bone loss

• Blend of two zirconium oxide raw materials (3Y-TZP and 5Y-TZP) without any visible layers

• Progressively increasing translucency in the incisal zone, smooth shade progression and progressively higher flexural strength up to 1200 MPa in the cervical zone

• High-end esthetics comparable to lithium disilicate

• 4 Bleach BL shades

• 16 A-D shades

• Disc thicknesses: 16 mm, 20 mm, 25 mm

Due to its high mechanical stability of 1200 MPa flexural strength[4], IPS e.max ZirCAD Prime covers all major applications – from single crowns to 14-unit bridges. Furthermore, it allows very thin, minimally invasive restorations to be made.

• Full-contour crowns

• full-contour 3-unit bridges

• full-contour bridges composed of 4 or more units with max. 2 pontics

• crown copings

• bridge frameworks composed of 3 or more units with max. 2 pontics

MDT Vincent Fehmer (Switzerland) talks about the differences between conventional multi-layer zirconia and IPS e.max ZirCAD Prime. He mentions the smooth progression of shade and translucency within the disc in particular.

It takes only a few steps to produce esthetic monolithic restorations. Additional staining or layering is unnecessary in most cases. Simple polishing or glazing is adequate for achieving an accurate match with the A-D shade guide. Efficiency and a low susceptibility to error are decisive benefits of the product.

• Straightforward polishing with OptraGloss or glazing with the fluorescent IPS Ivocolor glazing paste

• Reliable and reproducible process

• Minimal manual effort, yet impressive natural-looking* results

• For crowns and 3-unit bridges

• For restorations of a consistently high level of esthetic quality

• Blend of the two zirconium oxide raw materials 4Y-TZP and 5Y-TZP without any visible layers

• Progressively higher translucency in the incisal zone, harmonious shade progression and increasing flexural strength up to 650 MPa in the cervical zone

• 4 Bleach BL shades 

• 16 A-D shades

• Disc thicknesses: 14 mm, 16 mm, 20 mm

Gradient Technology (GT) is the key to the genuinely seamless progression of shade and translucency within the disc, the outstanding accuracy of fit of the product and its efficient processing properties. It is based on a blend of two zirconium oxide raw materials of different strengths and optical characteristics.

• Optimally coordinated shade

• Highest translucency in the incisal zone

• Highly esthetic 5Y-TZP zirconium oxide

• Flexural strength: 650 MPa[2]

• 3-mm thickness, irrespective of the disc thickness

• Seamless, layer-free transition zone

• Natural shading from dentin to enamel

• Increasing translucency in the incisal zone

• Increasing flexural strength in the cervical zone

• 4-mm thickness, irrespective of the disc thickness

• Maximum stability in the tooth neck zone

• Coordinated shading and opacity

• ZirCAD Prime Esthetic: high-strength 4Y-TZP zirconium oxide featuring 850 MPa[3] flexural strength

• ZirCAD Prime: high-strength 3Y-TZP zirconium oxide featuring 1200 MPa[4] flexural strength

• Thickness varies depending on the disc thickness 

The unique Gradient Technology (GT) is at the heart of IPS e.max ZirCAD Prime. Innovative processing technology is used to manufacture the disc using a combination of two zirconium oxide raw materials (3Y-TZP or 4Y-TZP with 5Y-TZP) to produce the striking properties of the IPS e.max ZirCAD Prime material.

All IPS e.max ZirCAD Prime discs – irrespecitve of their thickness – have an incisal zone of 4 mm. It is composed of an ultra-translucent 5Y-TZP zirconium oxide material. The layer-free transition zone, which is significantly responsible for the highly esthetic appearance of the material, is produced as a result of the Gradient Technology and it is 3 mm thick. 
The thickness of the dentin zone, which is composed of high-strength 4Y-TZP (IPS e.max ZirCAD Prime Esthetic) or 5Y-TZP zirconium oxide (IPS e.max ZirCAD Prime), varies depending on the thickness of the various discs. It ranges from 7 mm in the 14-mm disc up to 18 mm in the 25-mm disc.
