All-ceramic restorations have long become standard practice. Patients expect esthetically pleasing, long-lasting restorations. This means selecting the right material is essential, as it affects not only treatment outcomes and patient satisfaction, but also enhances efficiency and cost effectiveness. Long-term studies show survival rates above 95% – clear evidence of the high clinical reliability of IPS e.max.

Clinical evidence inspires confidence

Not all all-ceramic materials deliver on their promises. Only products whose quality is supported by independent, validated long-term studies provide reliable assurance. Reliability often means fewer material-related complications and greater patient satisfaction.

Quality is measurable – and offers economic advantages

High survival rates objectively demonstrate how reliably a product performs over time – and how rarely re-treatments are needed. Clinically proven, long-lasting products not only save time and costs and increase patient satisfaction, but also provide predictability in indication, preparation and cementation.

Additional factors affecting long-term success

The performance of restorative materials depends not only on their composition but also on the manufacturing process in the laboratory, preparation technique and the method and care taken during cementation. These aspects directly impact the clinical outcome. Informed material selection and professional handling ensure optimal, durable results over the long term.  

IPS e.max – clinically proven long-term quality with survival rates exceeding 95%

For over 20 years, the IPS e.max product family has delivered highly esthetic, clinically proven restorations. Glass-ceramic materials such as IPS e.max Press and IPS e.max CAD have achieved survival rates around 95% in long-term studies with observation periods of up to 17 years – a result unmatched among LS2-based glass-ceramics.
Similarly impressive, IPS e.max ZirCAD zirconium oxide has demonstrated documented survival rates of 99% in studies spanning up to five years – clear evidence of its high clinical durability.

Conclusion: Long-term success with quantifiable quality

Long-term successful restorations are no accident – they are the result of sound material selection, precise fabrication and a commitment to excellence. Quality pays off not only clinically, but also economically. And quality backed by scientific evidence builds greater confidence than marketing claims alone. The latest IPS e.max Scientific Report Vol. 4 summarizes the clinical results of numerous studies on IPS e.max, offering a concise and clearly structured reference for anyone who values evidence-based quality.
