Saya Dent Terauchi File Retrieval Kit (TRFK)

The Terauchi File Retrieval Kit (TFRK) is the ultimate solution developed by Dr. Yoshi Terauchi to effectively retrieve broken or separated endodontic files within the root canals of teeth
Given the complexity of root canal situations, TRFK brings together a variety of instrument retrieval tools to ensure effortless and effective retrieval

Can be used when the canal curvature is <15° and the coronal diameter of the broken file is 0.45mm
The inner depth of the MT is 1mm to expose 1mm portion of the broken file
Spin the MT at 600 rpm counterclockwise in a short in/out motion to expose the coronal 1mm portion of the broken file after the canal enlargement wither the MGG #3 rotating at 2500rpm to the broken file
If the canal curvature is >15° a size #60/.02 taper flexible NiTi rotary file should be used to enlarge the canal to the broken file
Inner diameter of the MT is 0.5mm diameter whereas the outer diameter of the MT is 0.8mm

Has extremely fine spear-shaped tips with a smooth surface for bypassing ledged canals and exploring the canal for broken files or other impediments
This instrument can be bent to meet the canal curvature so that the TRFK tips can be precurved the same way as it is before use
When there is a ledge formed coronal to the separated file in the canal, the explorer can be used to locate the original canal and the eldge can be reduced by using it with several push-pull strokes

The pilot tip of the Gates Glidden Drill is cut off, so that the root canal to the broken file can be enlarged to atleast 0.45mm as the tip diameter of the MGG #3 is 0,45mm
Is is used at 2,500rpm clockwise with a brushing motion against the outer wall to create a funnel shape.

60%, 2% Taper, NiTi file in the martensitic phase at 37°C
If the coronal diameter of the broken file is >0.45mm or the canal curvature is >15° use this rotary instrument to enlarge the canal to the broken file at 500rpm counterclockwise

TRFK-S is characterized by an extremely sharp cone-shaped tip: 0.1mm diameter tip with a 1% taper that can be pre-curved to be adapted to the canal curvature
Features:

Extend the grooved space to a 180° semicircular ditch until the broken file is seen dancing after the 90° semicircular space created on the inner wall with the Katana V or Katana H
Remove the broken file
Create a thin space between the canal wall and gutta-percha root fillings for the introduction of the TRFK-GPR
Remove necrotic pulp tissues and debris from an isthmus or a thin space

TRFK-V is designed with an extremely thin sword-shaped tip to create a 90° semicircular ditch on the inner wall of the broken file
TRFK-V can be pre-curved to be adapted to the canal curvature
Activate ultrasonics with the flat surface directed to the broken file from the inner wall of the canal
Feature:

TRFK-H is designed with an extremely thin sword-shaped tip to create a 90° semicircular ditch on the inner wall of the broken file
TRFK-H can be pre-curved to be adapted to the canal curvature
Activate ultrasonics with the flat surface directed to the broken file from the inner wall of the canal
Feature:

Used to retrieve the broken file after loosening it in preparation with ultrasonics when the broken file is longer than 4.5mm or the broken file did not come out with ultrasonics in 10 seconds at removal attempts
The loop size is adjusted to the diameter of the broken file with an endodontic explorer and bent to 45° to facilitate the placement of the loop over the broken file
The loop cannula is replaceable
The damaged loop can be quickly and easily replaced with a new loop
The maximum diameter of the microtube holding the loop is 0.5mm and it has a 23mm length
The microtube can be pre-curved to facilitate its placement into the root canal

A silicone rubber-based tool used with a straight handpiece
It is designed for sharpening ultrasonic tips to the desired shape and can also be used for polishing to enhance sharpness
