Advanced Nonsurgical Endodontic Retreatment and Fractured Instrument Removal. Hands-On Course by Yoshi Terauchi, Module 2 (Extended Participation Package)

With Yoshi Terauchi, you will expand your expertise in endodontics, where even the most complex clinical cases are transformed into structured, predictable protocols, and clinical confidence becomes an integral part of your daily practice.

This advanced hands-on course by Yoshi Terauchi provides a comprehensive and systematic approach to complex endodontic treatment, including the management and shaping of C-shaped root canals, ledge bypassing, and retrieval of visible and invisible separated instruments from curved canals, as well as instrument fractures located in the apical third of the root.

You will experience two intensive days of advanced theoretical learning and hands-on practice.

During the seminar, you will learn about:

– Diagnosis and treatment planning for endodontic retreatment cases
– Management of ledged canals, including prevention of ledge formation and predictable, efficient bypass techniques
– Contemporary concepts for predictable and minimally invasive retrieval of visible and invisible instrument fragments
– Modern treatment approaches for endo-perio lesions.

During the hands-on session of the course, you will:

– Practice diagnosis and treatment planning for cases involving invisible instrument fragments
– Master root canal preparation protocols prior to instrument retrieval
– Apply ultrasonic retrieval techniques in challenging clinical situations
– Use combined retrieval protocols with ultrasonic and rotary instruments
– Select the most appropriate techniques for safe instrument retrieval and ledge bypassing
– Prevent complications and effectively manage clinical errors.

This is more than just a course— it’s the result of many years of clinical experience transformed into clear protocols and delivered directly from the lecturer to your everyday clinical practice.

Program

The Extended Participation Package includes Yoshi Terauchi endodontic kits for root canal retreatment procedures.
