Desobturation made easy
D-Race instruments are used to remove most of the old root-filling material, such as Gutta Percha, obturators or resin-based material, from the canals.
The D-Race set consists of two NiTi files – DR1 and DR2. The first instrument, DR1, has an active tip for handling the root-filling material and is used in the first millimetres of the coronal and straight part of the canal.
Once access is cleared with the DR1, the second instrument, DR2, is used to reach the WL. As this work puts a lot of strain on the instrument, it is intended for single use. Shaping will be carried out using dedicated FKG instruments.
- 2 instruments: DR1 30/.10, DR2 25/.04
- Lengths: DR1 15 mm, DR2 25 mm
- Optimal speed DR1: 1’000 rpm (minimum 800 rpm)
- Optimal speed DR2: 600 rpm (minimum 400 rpm)
- Torque: 1.5 Ncm
- DR2: single use
