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 (1 mm)[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]:
- 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), see page 60-65.

[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.

[8] The survival rate of monolithic IPS e.max CAD posterior crowns was evaluated with the Kaplan-Meier method. The failure rate refers to technical failures such as fractures and chipping, R&D Ivoclar, Schaan.
