Lithium disilicate glass-ceramics (LS2)
IPS e.max® CAD is the best-selling glass-ceramic[1] worldwide. The material enables the efficient fabrication of full-contour restorations. It is distinguished by its flexibility, versatile field of applications and processing options and its high strength of 530 MPa.[2]
Both its aesthetic properties and durability have been confirmed in everyday clinical practice.[3-5]
Processing options:
“Blue” restorations can be:
- Polished and crystallised
- Glazed and crystallised in a single step
- Stained, glazed and crystallised in a single step
Types of restorations:
- Minimally invasive crowns (1mm)[6]
- Crowns
- Three-unit bridges (up to the second premolar as the terminal abutment)
- Implant-supported hybrid abutment restorations (hybrid abutments[7], hybrid abutment crowns)
- Veneers and occlusal veneers
- Inlays, onlays, partial crowns
Benefits:
- Excellent aesthetics and high flexural strength of 530 MPa[2]
- 97.2% survival rate of posterior crowns over a period of 10 years[8]
- Efficient grinding and crystallisation of posterior crowns in only 19:17 minutes[9]
- Broad spectrum of restorations for your chairside CAD/CAM applications
- 10-year guarantee
- Suitable for conventional, adhesive or self-adhesive cementation techniques
Block sizes[7]:
- 6 (I12, C14, C16, B32, B40 and B40 L) and 2 abutment block sizes (A14, A16)
Translucency levels[7]:
Given their high translucency, HT blocks are ideally suited for the fabrication of small restorations (e.g. inlays, onlays). Restorations made from HT blocks blend in naturally with their surroundings due to their chameleon effect.[10]
- 4 levels and 2 Impulse blocks (HT - High Translucency, MT - Medium Translucency, LT - Low Translucency, MO - Medium Opacity)
Shades[7]:
- Comprehensive range of shades: in A-D and BL shades (the range of shades varies depending on the translucency level).

[6] Long-term clinical evidence and the material’s high strength allows the recommendation for crowns with a minimum layer thickness of 1mm in combination with an adhesive cementation method.
