Program
Advanced endodontic techniques with Yoshi Terauchi and a unique opportunity to explore his signature non-surgical root canal retreatment protocols at an intensive seminar!
You will gain a systematic and in-depth understanding of key aspects of retreatment:
– Accurate diagnosis and treatment planning for non-surgical retreatment
– Effective and safe techniques for removing gutta-percha and bacterial biofilms from root canals
– Methods to prevent and bypass ledges in canals using predictable and practical approaches
– Innovative root canal obturation techniques using MTA.
This seminar is not just a transfer of knowledge — it’s an opportunity to transform your clinical approach to the most complex endodontic cases.
VIP participants will have the unique opportunity to participate in the practical part of the course in a «free audience» format. You attend the practical part of the training. See how the lecturer performs each action and get detailed step-by-step reviews of all clinical solutions. This is an opportunity to see real techniques live and to better understand the doctor’s logic, but without the opportunity to work with your hands. |
