Studies on the IPS e.max all-ceramic system

The 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 zirconium oxide materials for the press and CAD/CAM technique. The system is complemented by a universally applicable nano-fluorapatite glass-ceramic which is suitable for veneering all the components of the system.

Attractively presented scientific data
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, success cases and survival rates can be found in the new, clearly arranged IPS e.max Scientific Report.

Overall survival rate for the entire system of 96.8 per cent
The Report summarizes data on the clinical performance of IPS e.max that cover longer periods of time: up to five years for zirconium oxide 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.

Data on the individual system components
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 the individual components. The lithium-disilicate glass-ceramics IPS e.max Press and IPS e.max CAD, the zirconium oxide-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 per cent. The IPS e.max Scientific Report Vol. 01/2001–2011 in English is available for downloading on www.ivoclarvivadent.com.
