Description
Description:
The kit consists of:
1-TFRK-Gutta-Percha Removal Hand Instrument (TFRK-GPR)
Made of stainless steel, 4% taper.
It can be pre-curved to match the curvature of the channel.
With delta cones (maximum diameter: 0.35 mm) on both ends Used for the removal of filler material residues and for the removal of necrotic pulp tissue or debris in a confined space. The smaller pyramidal tip can make it easier to scrape gutta-percha from the canal wall.
2-TFRK-Micro-Explorer (TFRK-ME)
Made of stainless steel, a sharp explorer with 0.1mm diameter tip, double end, 6% taper, smooth surface. The TFRK-ME has extremely fine spear-shaped tips with a smooth surface to bypass overhanging channels and scan the channel for damaged rows or other impediments. This tool can be bent to fit the curvature of the channel so that TFRK bits can be pre-bent in the same way they are before use. When there is a protrusion formed coronally to the separate instrument in the channel, the TFRK-ME
can be used to locate the original channel, and the protrusion can be reduced by using it with several push-pull strokes.
3-TFRK-Micro-Trephine bur (TFRK-MT)
The inner diameter of the MT is 0.5 mm while the outer diameter of the MT is 0.8 mm. TFRK-MT can be used when the curvature of the channel is < 15° and the coronal diameter of the broken file is
0.45 mm. The internal depth of the MT is 1 mm to expose a 1 mm portion of the broken file. Rotate the MT at 600 rpm counterclockwise with a short entry/exit motion to expose the 1 mm coronal portion of the broken file after channel widening with MGG No. 3 rotating at 2500 rpm on the broken file. If the curvature of the channel is >150, you need to use a No. 60/.02 taper flexible NiTi rotary file to enlarge the channel of the broken file.
4-Modified Gates Glidden Drill #3 (MGG #3)
The pilot tip of the Gate Glidden Drill #3 is cut so that the root canal of the broken file can be widened to at least 0.45 mm since the tip diameter of the MGG #3 is 0.45 mm. It is used clockwise with a brushing motion against the outer wall to create a funnel shape.
5-Martensitic-phased NiTi Rotary Instrument K-Endo (K6 N60 2% L25)
60% NiTi files, 2% taper at 37°C. If the coronal diameter of the broken file is >0.45 mm or the curvature of the channel is >15", use this rotary tool to widen the channel to the broken file at 500 revolutions per minute counterclockwise.
6-Broken File Removal Tips (E87, E88, E89)
TFRK-Katana V/H is designed with an extremely thin sword-shaped tip to create a 90-degree semicircular moat on the inner wall of the broken file. They can be pre-curved to match the curvature of the channel. Activate the ultrasound with the flat surface directed towards the broken file from the inside of the canal wall.
7-TFRK-Loop (TFRK-L: Yoshi Loop)
Used to recover the broken file after loosening it in preparation with ultrasound when the broken file is longer than 4.5 mm or the broken file has not come out with ultrasound within 10 seconds during removal attempts. The size of the loop is adjusted to the diameter of the broken file with an endodontic probe and bent at 45 degrees to facilitate the placement of the loop on the broken file. The ring cannula is replaceable. The damaged loop can be quickly and easily replaced with a new loop. Two ring wire sizes are available: 0.12 mm and 0.08 mm, suitable for different clinical situations with different root canal diameters and strengths. The maximum diameter of the microtube that supports the loop is 0.5 mm and has a length of 23 mm. The microtube can be pre-curved for easy placement in the root canal.
