Clinical Tips
Adaptive motion: automatically transitions between rotation and reciprocation based on canal stress (per product page)
R-Phase NiTi is twisted (not ground) — preserves grain structure, reduces microfractures (per manufacturer)
Files can be pre-curved (R-Phase allows shape setting at lower temperatures)
Simplified technique: #10/#15 SS files → Traverse .13/.06 → TF Adaptive ML1 handles majority of anatomies (per current product page)
Adaptive motion automatically adjusts to canal load — may reduce instrument stress compared to fixed-motion systems (per manufacturer positioning)
Color-coded traffic light system: Green = Go, Yellow = Continue/Stop, Red = Stop
8:1 contra-angle handpiece required
Available in 23mm and 27mm lengths only
Warnings
- REQUIRES Kerr Elements Motor or elements e-motion — do not use with standard rotary motors
- Motor must be set to TF Adaptive program mode — never use continuous rotation
- Contains nickel — do not use on patients with nickel allergy
- File unwinding is a cautionary sign — reduce hand pressure or discard
- Inspect for distortion or deformation before each use
- Do not leave file at working length under load — advance and withdraw
Obturation Techniques
Single cone, warm vertical, carrier-based & lateral compaction
