Keynote: Why did that bridge fail? The eye opening use of fractography for clinical fractures of fixed prosthetics

OHSU School of Dentistry is pleased to welcome Susanne Scherrer, D.D.S., D.M.D., P.D., Professor, Head of Biomaterials, and Head of Continuing Education at the University Clinics of Dental Medicine, University of Geneva, Switzerland to present the Keynote Address at SOD Research Day 2022. The keynote and awards presentations are expected to begin at 12:00pm PST on March 3. The live keynote will take place in the Knight Cancer Research Building (KCRB) Auditorium, 2720 S Moody Ave (RSVP required for live attendees), and will be broadcast virtually via WebEx. 

Dr. Scherrer graduated with a DDS from the University in Geneva in Switzerland. She continued with part-time training in Fixed Prosthodontics from 1984-1989 and obtained a doctoral degree (Dr.Med.Dent) in 1986. From 1989-91 she was a Visiting Assistant Professor at the University of Texas HSC at San Antonio in the Department of Restorative Dentistry. In 2003, she obtained her Private Docent (PD) title from the University of Geneva. Dr. Scherrer is past President of the IADR-DMG (Dental Materials Group) (2001-02) and the Academy of Dental Materials (2002-04). In 2014, she was awarded the IADR-Distinguished Scientist Wilmer Souder Award from the Dental Materials Group. She is a fellow of the Academy of Dental Materials and the Academy of Prosthodontics. She currently serves on the Editorial Boards of the JADA Foundation Science and the Swiss Dental Journal. Her primary area of research and publishing involves dental ceramics, mechanical properties, clinical longitudinal trials, and failure analysis using fractography. She has worked as a general practitioner from 1984-2015 in extramural family private practices.

Keynote Abstract: The failure of a fixed dental restoration can cause significant pain, inconvenience and cost. Critical examination of broken prosthetics can inform the practitioner about the cause of failure and alert them to the critical design parameters to ensure future success. This presentation will follow through an investigation of a series of actual clinical cases examining the retrieved fractured portions of zirconia bridges and resin composite endocrown restorations, using the scientific tool of fractographic failure analysis. These cases will highlight issues related to material science, lab processing, design, surface treatment, occlusal loading contacts and the important lessons that can be learned from such premature fractures. 

Participants are eligible to earn 1 CDE credit for attending this presentation.
