Clinical Tips
- Orifice opener (17/.08) operates at 300 RPM / 3.0 Ncm; all other files at 350 RPM / 2.5 Ncm (per Eighteeth series brochure). Note: a distributor spec (Alkaramdent) lists a flat 350 RPM / 2.0 Ncm — series brochure from eighteeth.com is used here as the manufacturer source.
- Gold heat-treated Control Memory NiTi wire provides enhanced flexibility and cyclic fatigue resistance (per brochure).
- The system includes an integrated orifice opener (17/.08, 19mm) and glider (19/.02) — no separate glide path system needed.
- Available in three sub-variants: Standard (.04 taper files with orifice opener + glider), .06 Taper (sizes 15-35), and Wide Canal (.04 taper, sizes 20-50) (per specs).
- Non-cutting safety tip reduces ledge formation and apical extrusion; variable pitch reduces screw-in tendency (per series brochure).
Warnings
- No standalone IFU is publicly available for E-Flex Gold; data sourced from Eighteeth series brochure (eighteeth.com, 2022) and distributor spec (Alkaramdent). Settings may differ between documents — verify with current manufacturer literature.
- Orifice opener: 300 RPM / 3.0 Ncm; shaping files: 350 RPM / 2.5 Ncm (per series brochure)
- Contains nickel-titanium — do not use on patients with known nickel allergy
- Inspect instruments before use; discard if visible defects

What motion type does E-Flex Gold use?
What motion type does E-Flex Gold use?
Answer
E-Flex Gold uses continuous rotation motion.
What cases is E-Flex Gold best for?
What cases is E-Flex Gold best for?
Answer
E-Flex Gold is best suited for: cost-effective gold heat-treated rotary system, integrated workflow (orifice opener + glider + shaping in one family), uniform 350 RPM / 2.5 Ncm across the shaping sequence (opener: 300 RPM / 3.0 Ncm).
