Use BR0 (25/.08) with only 4 gentle strokes, clean the flutes. Repeat until approximately 4-6 mm of the coronal canal is prepared. After BR0, irrigate and recapitulate to full working length with a #15 manual file (per IFU). _(File: BR0 · 600 RPM · 1.0 Ncm)_ - BR0 has a partially active tip (unlike other BioRaCe files which have non-cutting tips) (per brochure) - Only 4 gentle strokes before cleaning the flutes (per IFU golden rules) - After BR0, recapitulate to full WL with a #15 manual file (per IFU) - Fill canals and pulp chamber with irrigant before and after BR0 (per IFU) - ⚠ BR0 is for coronal pre-flaring only; do not advance to full working length ### Shaping 1. **Sequential Shaping: BR1 through BR3** — Use BR1 (15/.05) with 4 gentle strokes. If BR1 does not reach working length, clean the instrument and repeat until working length is achieved. Use BR2 (25/.04) and BR3 (25/.06) in the same manner. Do NOT use BR3 to full WL on canals with severe apical curvatures — switch to the Extended Set protocol (per IFU). _(600 RPM · 1.0 Ncm)_ - Max 3-4 back-and-forth gentle strokes per pass; light touch, let the instrument work (per IFU golden rules) - Work 3-4 seconds at a time, then withdraw, clean the blade, and irrigate (per IFU golden rules) - Copious irrigation between each instrument change (per IFU) - ⚠ Do NOT use BR3 (25/.06) to full WL on canals with severe apical curvatures (per IFU) - ⚠ If BR3 cannot reach WL safely, switch to Extended Set (BR4C + BR5C) for the apical portion (per IFU) ### Finishing 1. **Final Apical Preparation: BR4 and BR5** — Use BR4 (35/.04) and BR5 (40/.04) as described for BR1-BR3. In most cases, the final apical preparation is then achieved. For larger canals, use BR6 (50/.04) and BR7 (60/.04) from the Extended Set. For severe curvatures, BR4C (35/.02) and BR5C (40/.02) provide safer apical preparation (per IFU). _(600 RPM · 1.0 Ncm)_ - BR4 and BR5 complete the preparation in most standard cases (per IFU) - BR4C and BR5C (.02 taper) are specifically for severe apical curvatures (per IFU) - BR6 and BR7 extend the preparation for larger canals (per IFU) - Irrigate copiously between each instrument; cleaning after 4 strokes is essential (per IFU) ## Clinical Tips - All BioRaCe files operate at 600 RPM and 1.0 Ncm (per IFU golden rules). Brochure suggests 500-600 RPM range. FKG speed/torque chart shows 1.5 Ncm as the torque limit. - The BioRaCe technique (Debellian & Trope) focuses on biological preparation: thorough cleaning and disinfection through a crown-down approach with copious irrigation (per brochure). - BR0 (25/.08) has a partially active tip for coronal pre-flaring; all other BioRaCe files have non-cutting safety tips (per brochure). - Alternating cutting edges reduce screw-in tendency; electropolished surface may improve fatigue resistance (per brochure). - The Extended Set (BR4C, BR5C, BR6, BR7) is separate from the Basic Set and provides options for severe curvatures (.02 taper) and larger canals (50-60/.04) (per IFU). - Single patient use is recommended to avoid cross-contamination (per IFU). If reprocessed, autoclave at 134°C, 2.2 bar, 18 min per EN/ISO 17664 protocol. ## Warnings - Single patient use is recommended to avoid cross-contamination (per IFU) - Do NOT use BR3 to full WL on canals with severe apical curvatures (per IFU) - Do NOT force instruments; if WL is not reached with 4 strokes, irrigate and repeat (per IFU) - Contains nickel — do not use on patients with known nickel allergy (per IFU) - Always inspect instruments before use; discard if visible defects (per IFU) - Copious irrigation at all times; cleaning files after 4 strokes is essential (per IFU) ## Contraindications - Known nickel allergy (per IFU) ## Best for - biological crown-down preparation (Debellian & Trope technique) - comprehensive file range from coronal pre-flaring to large canal finishing - severe curvatures via Extended Set (.02 taper BR4C/BR5C) ## Technical profile - **Category:** multi-file-rotary - **Heat treatment:** Conventional — Conventional NiTi with electropolished surface. Alternating cutting edges for reduced screw-in tendency. - **Manufacturing method:** ground - **Pre-bendable:** no - **Reuse:** Reusable (limited) - **Motor:** any-rotary - **Glide path requirement:** manual-only - **Canal suitability:** Curvature: mild, moderate, severe; Canal size: narrow, normal, wide; Calcified canals: no; Retreatment: no; Conservative access: no - **Content revision:** 2026-03-22 ## FAQ **What alloy is BioRaCe made from?** BioRaCe® is manufactured from Conventional NiTi (Electropolished). **How many files are in the BioRaCe sequence?** The BioRaCe® system includes 10 files: BR0, BR1, BR2, BR3, BR4, BR5, BR4C, BR5C, BR6, BR7. **What is the BioRaCe file sequence?** BioRaCe® is used in this order: BR0 → BR1 → BR2 → BR3 → BR4C → BR5C → BR4 → BR5 → BR6 → BR7. Per-file speed, torque and technique are in the protocol section above. **What motion type does BioRaCe use?** BioRaCe® uses continuous rotation motion. **What cases is BioRaCe best for?** BioRaCe® is best suited for: biological crown-down preparation (Debellian & Trope technique), comprehensive file range from coronal pre-flaring to large canal finishing, severe curvatures via Extended Set (.02 taper BR4C/BR5C). **What speed and torque settings are recommended for BioRaCe?** Recommended settings: 600 RPM and 1.0 Ncm across the file sequence (refer to official DFU for full per-file parameters). ## References - [Manufacturer instructions for use (DFU/IFU)](https://kris95.bg/wp-content/uploads/2022/02/FKG-BioRace-IFU.pdf) ## Related - [HTML page](https://endo-guide.app/system/biorace) - [Manufacturer hub: FKG Dentaire Systems](https://endo-guide.app/manufacturer/fkg) - [Compare systems](https://endo-guide.app/compare) - Other languages: [Türkçe](https://endo-guide.app/tr/system/biorace.md) · [Español](https://endo-guide.app/es/sistema/biorace.md) - [llms.txt](https://endo-guide.app/llms.txt) · [EndoGuide (Markdown)](https://endo-guide.app/index.md) --- _Educational reference for dental professionals.
