TFRK: The Ultimate Instrument Retrieval Solution

Given the complexity of root canal situations, TFRK brings together a variety of instrument retrieval tools to ensure effortless and effective retrieval.

TFRK-Gutta-Percha Removal Hand Instrument (TFRK-GPR)

Made of stainless steel, 4% taper Can be pre-curved to fit the canal curvature With delta cones (max. diameter: 0.35 mm) on both end Used for the removal of filling material remnants and for the removal of necrotic pulp tissues or debris in a narrow space. Smaller size pyramidal tip can make it very easy to scrape gutta-percha root fillings from the canal wall.

TFRK-Micro-Explorer (TFRK-ME)

Made of stainless steel, a sharp 0.1 mm-tip-diameter explorer, double ended, 6% taper, smooth-surfaced.The TFRK-ME 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 TFRK 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 TFRK-ME can be used to locate the original canal and the ledge can be reduced by using it with several push-pull strokes.

TFRK-Micro-Trephine bur (TFRK-MT)

Inner diameter of the MT is Φ0.5 mm whereas the outer diameter of the MT is 0.8 mm. TFRK-MT can be used when the canal curvature is <15˚and the coronal diameter of the broken file is 0.45 mm. The inner depth of the MT is 1 mm to expose a 1 mm-portion of the broken file. Spin the MT at 600 rpm counterclockwise in a short in/out motion to expose the coronal 1 mm-portion of the broken file after the canal enlargement with the MGG #3 rotating at 2500 rpm 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.

Martensitic-phased NiTi Rotary Instrument K-Endo (K6 N60 2% L25)

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