Leaving a difficult year 2021 behind us (when we had to cancel all our activities) we are now happy to announce a new release of the Fracto Course in 2022. Different from previous years we are this year connected to the annual meeting of the Academy of Dental Materials and plan for October 2-5 in the mediterranean vicinity to Athens, Greece.
The focus of this 3 days course is still on hands-on practical and clinical aspects related to in vitro and in vivo fractography.
The place is not yet confirmed, but we are searching for a suitable resort type venue close to Athens.
We are again planning with 20 participants and aim to present a balanced mix between basic knowledge into fractography, hands-on with stereo microscopes, and interactive case presentations in clincial fractography.
For orientation purposes, the 2019 Fracto Course programme can be downloaded here:
The program is spread over 3 days. The registration fee for the 2022 Fracto Course is 900,00 € and includs the FFI membership fee for 2022, comprehensive course material (book and script) as well as food & beverages during the day and a social dinner on one of the course days.
Registration Procedure (For future courses):
Send an E-Mail to: firstname.lastname@example.org. The participants will be taken on a first come first serve basis. We will respond with acceptance as soon as possible!
After acceptance, please submit the Registration fee (900,00 €uro).
