Clinical Tips
All files use 280 RPM (recommended; range 250-350 RPM per IFU). Torque is size-specific: 1.2 Ncm (10/.04), 1.3 Ncm (15/.05), 2.1 Ncm (20/.06), 2.3 Ncm (25/.06). VDW motors have pre-programmed Mtwo settings.
Simultaneous Shaping means each file goes to full working length — no crown-down staging. This preserves tooth substance compared to coronal-first techniques.
Brushing file movement: when resistance is felt, pull back 1-2 mm and stroke laterally against the canal wall (like a Hedstroem file), then allow the instrument to re-advance apically.
No separate coronal flaring is needed — Mtwo's lateral cutting efficiency gradually widens the canal entrance with each file used.
Apical gauging with ISO #30 hand file after the basic sequence determines if further enlargement is needed.
Retreatment files R15/.05 (narrow canals, 0.3 Ncm) and R25/.05 (medium/wide canals, 1.2 Ncm) have active cutting tips for gutta-percha removal.
Compatible with VDW.GOLD RECIPROC, VDW.SILVER RECIPROC, and VDW.CONNECT Drive motors (pre-programmed Mtwo settings available).
Warnings
- Reusable sterile instrument per 2023 IFU — cleaned undamaged instruments validated for up to 8 processing cycles; silicone stops are single-use and must be replaced after each use
- VDW states it is safest to use Mtwo instruments only once — if reusing, document frequency with control stickers and inspect carefully
- Contains nickel — do not use on patients with known nickel allergy
- Do not use in root canals with abrupt apical curvatures — use pre-curved hand files instead (per IFU)
- Do not fully immerse in NaOCl — working part only, max 5% concentration (per IFU)
- Do not use in a picking movement — only brushing and automatic advancement
- Never force files apically — allow cutting action to progress naturally
- For extremely curved canals: consider single-canal use per file and visual inspection for deformation after every use (per IFU)
- Torque alarm signal indicates excessive stress — pull back, create space with brushing, then re-advance
