Clinical Tips
EDM manufacturing creates compressive surface stresses for superior fatigue resistance
CM-Wire allows pre-bending that persists during use
Spirals may lengthen in response to force - prevents binding and reduces breakage risk
Shape regenerates during autoclaving (or 10 sec in glass bead sterilizer) if elastically deformed
Files supplied pre-sterilized via gamma irradiation
Warnings
- Ensure spirals do not wind in opposite direction during use - causes plastic deformation
- If spirals appear lengthened after autoclaving, discard file
- Inspect for unwinding before each use
- Do not use after expiration date
- Discard if any visible defects observed
Obturation Techniques
Single cone, warm vertical, carrier-based & lateral compaction
