The average survival rates of the IPS e.max materials are summarized below:
IPS e.max Press (LS2)
The clinical studies covered study time periods from 3 years to 10 years and involved both crowns and/or bridges, which were luted either adhesively, self-adhesively or conventionally depending on the study.
IPS e.max CAD (LS2)
The clinical studies covered study time periods from 3 years to 10 years and involved both crowns and/or bridges, which were luted either adhesively or self-adhesively depending on the study.
IPS e.max ZirCAD (ZrO2)

The clinical studies covered study time periods from 2 years to 5 years. Depending on the study, crowns and/or bridges were investigated.
The most widely used all-ceramic system1
The IPS e.max system has had a lasting impact on the dental market. Its high esthetics, in combination with the excellent mechanical properties and outstanding technique tolerance, ensure high customer satisfaction and lead to exceptionally good clinical results. The results speak for themselves: Both lithium disilicate and zirconium oxide show an average survival rate of 96 per cent.
