We can also apply the technique for the removal of fractured instruments, as we see in this case of a second upper molar, which was referred with a broken lentulo inside the palatal canal, which blocked us from accessing the second palatine root (independent of the main root).

As we have seen in this article, if we have the knowledge, skill and adequate equipment, the braiding technique is a feasible, teachable and reproducible technique for the removal of plastic carriers and other materials inside the root canal.
