Denext Open Coil Spring

These Open Coil Spring gently and efficiently open and maintain space in a convenient cut to length design. Coil springs are used in orthodontics to deliver forces to move teeth. However, the optimal amount of activation to produce predictable, continuous deactivation forces, for the purpose of orthodontic tooth movement, is unclear. The purpose of this study was to evaluate the deactivation force characteristics of nickel-titanium open-coil springs after varying levels of activation.

Lastly, there were differences between manufacturers of coil springs. The load deflection curves varied for coil springs reportedly of the same size and material, but produced by different manufacturers.  Those manufacturers that incorporated more total wire in a given length of coil, meaning a higher pitch or more loops, produced lighter forces overall. All of the load deflection curves were reportedly similar in shape. Immediately thereafter, the curve was linear, meaning as the amount of compression increased, the amount of force also increased in a relatively proportional fashion. Chaconas et al.

2 Inserting an open coil spring is a cumbersome procedure. Failure to ligate the teeth properly can lead to rotation of the teeth.

Made from durable nickel titanium material.
