The JIZAI System is the newest addition to the MANI endodontic product line. 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.

Three foundational concepts form the basis of JIZAI.

  • 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.
  • Flexible respects the original anatomy. The heat treatment that each JIZAI undergoes results in a significantly lower risk of ledging, transportation, and perforation.
  • Simple describes how files shape severely curved canals with ease through procedural-based sequencing. Tip size and taper are etched on the shank.
