Ivoclar Vivadent adds average strength data to IPS e.max labelling

Ivoclar Vivadent has adjusted the sales strategy of its IPS e.max lithium disilicate to provide information on its average strength.

Based on the findings of 11 years of consistent quality tests, the ceramic material has been shown to offer an average biaxial flexural strength of 500 MPa, meaning it is able to deliver high success rates.

More than 100 million restorations have been carried out using the material since its launch in 2005, with a survival rate of more than 96 percent associated with the product. Internal quality tests have also shown that IPS e.max is able to meet the standards required of it.

Until now, Ivoclar Vivadent used minimum estimates when communicating relevant strength values, a conservative approach designed to provide a safety buffer for outlier cases, such as when processing instructions are not strictly followed.

Changing its policy will mean the required material thickness for IPS e.max lithium disilicate crowns can be reduced, with a thickness of only one mm now sufficient when crowns are adhesively cemented.

Patrik Oehri, director of research and development services and corporate quality management at Ivoclar Vivadent, said: "After decades of success and thousands of produced and tested batches, we will communicate the average strength from now on – like most other manufacturers."
