10 years of research on IPS e.max

A new Scientific Report from Ivoclar Vivadent for the first time brings together the most important studies on IPS e.max that have been conducted in the course of the past ten years.

More than 20 clinical in-vivo as well as further in-vitro studies have been compiled and are presented in a clearly structured manner. They attest to the successful performance and reliability of the IPS e.max system.

IPS e.max is an innovative all-ceramic restorative system which comprises lithium disilicate glass-ceramic and zirconia materials for both pressing and milling. The system is complemented by a universally applicable nano-fluorapatite glass-ceramic which is suitable for veneering all the components of the system.

Since the initiation of its development more than a decade ago, the IPS e.max system has been scientifically investigated on an ongoing basis. With their studies, many reputable experts have contributed to what has become a valuable resource for scientific data on IPS e.max. The most important study results, including details on test methods, successful cases and survival rates, can be found in the new, clearly arranged IPS e.max Scientific Report.

The Report summarizes data on the clinical performance of IPS e.max that cover longer periods of time: up to five years for zirconia and up to ten years for lithium disilicate. In addition, the overall survival rate for the entire system was calculated by combining the survival rates of IPS e.max Press (six studies), IPS e.max CAD (six studies) and IPS e.max ZirCAD (eight studies). These 20 studies involved a total of 1071 restorations. The overall survival rate for the IPS e.max system was calculated to be 96.8 per cent.

Apart from this result on the IPS e.max system as a whole, the Scientific Report also contains the results of clinical trials that focussed on individual components. The lithium-disilicate glass-ceramic IPS e.max Press and IPS e.max CAD, the zirconia-based IPS e.max ZirCAD as well as related products such as IPS e.max ZirPress and IPS e.max Ceram were examined. The survival rates of these materials ranged between 93.7% and 98.4%.
