Orthodontic springs are precision-engineered coil springs used in fixed-appliance therapy to deliver controlled forces for space opening, space closure, derotation and uprighting. Made from medical-grade stainless steel and nickel-titanium alloys, the ortho springs offer consistent force delivery, excellent shape memory and corrosion resistance. Available in open-coil and closed-coil designs across multiple diameters, lengths and force levels, each braces spring is accurately wound for predictable performance and simple engagement with archwires and brackets. A smooth finish reduces soft-tissue irritation for improved patient comfort, and packaging options suit both single-case use and bulk clinical needs. Ideal for routine and complex mechanics where reliable, precise force application is required.
