Order of operation:

Based on the memory function of the Nitinol material and its ductility, M3-Max is very flexible and resistant to cyclic fatigue, and can be used safely and effectively in a variety of root canal configurations, from the narrowest end to the widest end, and from the straight canal to the most curved root canal.
M3-Max causes almost no additional cutting and does not change the shape of the root canal after preparation. Using M3-Max, you can achieve the best cleaning results, killing germs, while preserving dentin.
This is a versatile cleaning file that can be used in combination with any nickel-titanium file system that prepares the root tip to size 25 or larger.

The working length of the root canal minus 2mm is the working length of M3-MAX
