Clinical Tips

Differentiated speeds per spec table: 350–500 rpm for 20/.07 + 15/.04, 800–1000 rpm for Twin Shaper 25/.02, 1000 rpm for 30/.04, 800 rpm for 30/.02 (per IFU spec table)

IFU step-by-step (section 7) only explicitly uses three files: 015/.04 (step 4, Glider — orifice opening), 030/.04 (step 5, named "shaper" but used for glide-path prep), and 025/.02 (step 6, Twin Shaper finisher). The 20/.07 (19 mm) and 30/.02 appear in the spec table but are not referenced in the IFU step-by-step — they may be optional alternates or coronal flares (per IFU)

Cross-section geometry is not described in the IFU text (no spec-card image extracted); brochure-style cross-section names should not be assumed

Storage conditions: 5–35 °C ambient, 30–75% relative humidity, dry and away from light (per IFU section 6)

Final autoclave: 121 °C / 20 min, 134 °C / 5 min, or 134 °C / 18 min for prion inactivation (per IFU sterilization section)

Warnings

Single-use; never reprocess or reuse (per IFU section 3)
Do not use autoclave above 138 °C, and never above 200 °C including drying (per IFU sterilization section)
Do not fully immerse in NaOCl; only the working part may contact a max 5% NaCl solution for up to 5 minutes (per IFU section 4)
Use only with proper torque-controlled handpiece and minimal apical pressure (per IFU section 4)
Safety not established in pregnant/breastfeeding patients or children (per IFU section 4)
Contraindicated in patients with nickel allergy (per IFU section 1)
