Design T-loops, L-loops, and vertical closing loops. Adjust gable bends, wire size, loop height, and position — and watch the force, the load-deflection rate, and the moment-to-force ratio update live.

Loop mechanics from beam theory — every number traces to the wire and the geometry.
T-loop, L-loop, and vertical closing loops — switch and compare their force systems.
Add gable bends and watch the moment — and therefore the root control — change.
See how wire size, loop height, and material set the force-per-millimetre you deliver.
Tune the moment-to-force ratio to target tipping, controlled tipping, or translation.
A custom closing loop in three moves.
Choose a T-, L-, or vertical loop and a starting wire.
Set the height, position, and gable bends — the beam model recomputes the force system.
See delivered force, load-deflection rate, and the M/F ratio at the bracket.
Loop force and stiffness come from validated beam-bending theory keyed to the wire’s cross-section and modulus — lower the load-deflection rate (taller loop, smaller wire) and watch the force become gentler and more constant, exactly as the literature describes.
For learning why a loop delivers the force it does.
Build real intuition before the clinic — change a parameter and watch the mechanics respond, instead of memorizing rules.
A fast sandbox to reason from first principles — concept-level understanding, never patient-specific advice.
A transparent, citable model for teaching and study. Every value traces to a published equation.
It is the force delivered per millimetre of activation. A lower rate gives a gentler, more constant force over the closing range — achieved with a taller loop, a smaller or more flexible wire, or added wire length.
Gable bends add a moment to the force system, raising the moment-to-force ratio so the roots are controlled during space closure rather than the crowns simply tipping together.
