MANI JIZAI NiTi File System

The JIZAI NiTi File System from Mani is smooth, flexible, and simple. Read more about how this system has improved on the NiTi file. 

JIZAI can be translated from Japanese to mean “being at will”

The JIZAI system is the newest addition to the Mani endodontic product line.

Three foundational concepts form the basis of JIZAI.

  1. Smooth designs provide an optimal cutting experience. Radial lands help prevent overinstrumentation and excessive engagement on the root canal walls. The off-center file axis is uniquely designed to provide a larger “pocket” space for debris removal during instrumentation.
  2. Flexible respects the original anatomy. The heat treatment that each JIZAI undergoes results in a significantly lower risk of ledging, transportation, and perforation.
  3. Simple describes how files shape severely curved canals with ease through procedural-based sequencing. Tip size and taper are etched on the shank.

Each file is fully heat-treated, highly flexible, and designed to cut smoothly and efficiently. The cross-sectional shape and flute pitch help prevent overinstrumentation and file binding. Each file can be pre-bent and will hold its shape. The Japan-manufactured files are available in individual ISO-sized packs of three files or as part of a Standard Kit, which includes a sequence of 25.04, 25.06, and 35.04 files designed to instrument straight and slightly curved canals.
