Removal of a nonvisible broken file followed by bypassing nonvisible ledge and RCP/見えない破折器具・レッジ除去・形成 

This looks like you would perforate the canal....opening it that wide. Best you leave it alone.

Good evening sir, Great skill, I m a dentist from India, perform Rct quiet well but unable to manage such cases of separated instruments, how can I learn this level of skill in endodontics, any course you conduct for advanced endodontics?? Or any book or hands on which can help me tackle such cases confidently.

In real life: Perforation+ 2nd file fracture 😂

Can you pls write down step by step the files you used and where to order ?

👏🏻

Its not an easy job to retrieve a broken file, It looks simple in such videos but there different type of composition of material tooth and plastic blocks,

Isn't it very destructive technique for retrival?
