Closed Coil springs are used to close spaces between teeth or more simply, to move points closer to one another. The coils are extended when loaded and provide retraction forces to close spaces.
Features
NiTi close springs with loop ends are designed to close spaces with consistent and predictable results.
They provide excellent results in closing spaces and anterior retraction.
They can be easily engaged to bracket hook or buccal tube hook.
In case the distance between two hooks exceeds expansion limits of this coil spring, use ligature with the close spring to engage hooks.
