Tomy Spooled Open Coil Springs are super-elastic orthodontic springs made of Nickel-Titanium (NiTi) or Sentalloy. They are designed to be easily cut to length and placed over an archwire to gently and consistently open, regain, or maintain space between teeth.
These spooled products are highly valued in orthodontics for providing continuous force without deforming over time. Common options from the manufacturer include:
** Sentalloy Spooled Open Springs: Known for their super-elastic properties, allowing the spring to be easily compressed while maintaining a gentle, consistent force.
** Ultra Light (Pink) Spools: Provide a lighter, continuous force rating (e.g., 25gf).
** Light (Blue) Spools: Offer a medium force rating (e.g., 100gf)
