Lecture Summary:

New materials and different combinations of materials are continually being introduced, often with great fanfare, promising improved aesthetics and long clinical lifetimes. Unfortunately, history has shown that they do not always live up to the marketing promises. So, are there laboratory tests that can predict clinical lifetimes? This presentation will summarize 10-years of research addressing damage initiation and propagation in all-ceramic posterior crowns. More importantly, it will highlight which test results clinicians can rely on as accurate predictors of future, in-vivo performance.


In January of 2012, Professor Rekow became Dean of King’s College London Dental Institute. Previous to that she earned degrees in dentistry and bioengineer at the University of Minnesota, chaired the Departments of Orthodontics at the University of Medicine and Dentistry of New Jersey and of Basic Science at New York University College of Dentistry. Immediately before joining King’s, she was the Provost of Polytechnic Institute of New York University where she served as chief academic officer. Professor Rekow’s research team was funded for over 10 years by the US National Institute of Standards and Technology and drew on expertise from 7 universities and 5 corporate partners. Their work in damage initiation and propagation in layered brittle ceramics has generated over 100 manuscripts in dental, engineering, and ceramic science journals as well as providing a training foundation for a number of students who are now dental faculty members around the world.
