NiTi Multi-taper Files are developed for modern mechanical preparation using Crown Down technique. Taper changes continuously from tip to handle for each file. With the unique multi-taper design, sharp cutting edge, good flexibility and excellent shaping efficiency, NiTi multi-taper files give dentists a brand new experience on root canal preparation.
a. Composition
- 6 pcs / set: 3 pcs of Shaping Files ( SX amber, S1 purple, S2 white ) and 3 pcs of Finishing Files ( F1 yellow, F2 red, F3 blue ), available of single or assorted sizes
- Length: 21mm, 25mm (always 19mm for shaping file SX)
* SX is used for shaping of the coronal and short root canal, S1 is used for the preparation of 1/3 section on the root canal coronal, S2 is used for the preparation of 1/3 section of the middle of root canal.
* F1, F2, F3 are used for the preparation of 1/3 section of the tip of root canal.
b. Characteristics
* Progressive taper design improves flexibility and cutting efficiency, especially in tighter or more curved canals
* Fewer files are needed to achieve a fully tapered canal
* Made of Ni-Ti alloy and available of hand use files and rotary files
* Recommended rotary speed of rotary files: 150~350 r/min
c. Clinic Key Points:
* Adopt crown-down method.
* Enlarging the root canal coronal in advance.
* Make sure the working length.
* The preparation of the mid-part of the root canal.
* The preparation of area of the root canal tip.
* Small size file put into root canal to keep the canal unblocked.
