How to Choose the Right Orthodontic Coil Spring for Your Practice
- Open vs Closed Coil Mechanics — An open coil spring is compressed between two archwire stops and pushes teeth apart to regain lost space, while a closed coil spring is stretched between a hook and a stop and pulls teeth together to close a gap or extraction site — the two work in opposite force directions.
- NiTi vs Stainless Steel Coil — NiTi coil springs maintain a flatter force-deflection curve over a wider range of activation, delivering more consistent light-to-moderate force as the coil compresses or stretches, while stainless steel coils deliver higher force per unit of activation but decay faster.
- Calibrated Force (g) — Coil springs are supplied in graduated force ratings, typically 100g-200g for space closure and regaining; selecting a force appropriate to root surface area and anchorage design avoids undermining posterior anchorage during closure.
- Helical Torque Springs — A helical torque spring incorporates coiled loops into an auxiliary wire to express controlled torque or uprighting force on a single tooth or short segment, distinct from a straight compression/extension coil.
- Eyelet Configuration — Coils supplied with surgical eyelets at each end allow direct ligature-tie attachment to hooks or brackets without needing a separate crimpable stop, simplifying chairside placement.
- Reactivation — Most coil springs can be reused across a visit or two if they have not been overstretched beyond their rated elastic limit, but force output should be re-measured rather than assumed once a spring has already been activated.
Coil Spring Types at a Glance
| Type | Direction of Force | Material | Best Suited For |
|---|---|---|---|
| Open Coil Spring | Pushes teeth apart | NiTi or steel | Regaining lost space before restoration/implant |
| Closed Coil Spring | Pulls teeth together | NiTi or steel | Extraction space or diastema closure |
| Helical Torque Spring | Rotational/uprighting | NiTi | Single-tooth torque or uprighting correction |
Availability & Delivery in Egypt
MedSTA supplies Matt Ortho, Aditek, and DTC coil springs priced in EGP with delivery to practices across Cairo, Giza, Alexandria, and all Egyptian governorates. Store NiTi coils away from direct sunlight and high heat, since prolonged exposure to Egypt's summer temperatures can affect the alloy's transformation temperature and force output over time.
Frequently Asked Questions
Open coil vs closed coil spring — what is the difference in clinical use?
Open coil vs closed coil spring — what is the difference in clinical use?
An open coil spring is compressed between two points on the archwire and pushes teeth apart to regain lost space, while a closed coil spring is stretched between a hook and a stop and pulls teeth together to close a gap or extraction site.
What NiTi coil spring force is typically used for space closure?
What NiTi coil spring force is typically used for space closure?
Space closure generally uses coil springs in the 100g to 200g range; the exact force should be matched to root surface area and anchorage design so that posterior anchorage is not undermined during the closing movement.
How does a helical torque spring differ from a standard coil spring?
How does a helical torque spring differ from a standard coil spring?
A helical torque spring incorporates coiled loops directly into an auxiliary wire to express controlled torque or uprighting force on a single tooth or short segment, whereas a standard coil spring is a discrete component that only compresses or stretches linearly.
Can orthodontic coil springs be reactivated or reused?
Can orthodontic coil springs be reactivated or reused?
Most coil springs can be reused for a visit or two if they have not been overstretched past their rated elastic limit, but the clinician should re-check the force output at each reactivation rather than assume it matches the original rating.
Does MedSTA supply NiTi and stainless steel coil springs across Egypt?
Does MedSTA supply NiTi and stainless steel coil springs across Egypt?
Yes. MedSTA delivers Matt Ortho, Aditek, and DTC coil springs to orthodontic practices across Cairo, Giza, Alexandria, and all Egyptian governorates, priced in EGP with nationwide delivery.
