What alloy is TF Adaptive made from?

TF Adaptive™ is manufactured from R-Phase NiTi (Twisted) with r-phase heat treatment.

How many files are in the TF Adaptive sequence?

The TF Adaptive™ system includes 6 files: SM1, SM2, SM3, ML1, ML2, ML3.

TF Adaptive™ uses continuous rotation motion.

TF Adaptive™ is best suited for: adaptive motion (auto rotation/reciprocation), severely curved canals, automatic load-based motion switching.

Recommended settings: Adaptive RPM and Adaptive Ncm across the file sequence (refer to official DFU for full per-file parameters).

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)

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
