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]:
MT blocks demonstrate medium translucency and are used for restorations that require more brightness than HT restorations and more translucency than LT restorations.

• 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).
