Implant Torque Calculator

Work out implant torque instantly with clear inputs, formula shown and shareable results.

About Implant Torque Calculator

Multiplies the applied force by the wrench lever arm to give insertion torque, and works out the force needed to reach a target torque.

Formula

Torque

Torque (Ncm) = force (N) x lever arm (cm); 1 Nm = 100 Ncm

Worked example

With the default values below, Implant Torque Calculator returns Applied torque of 37.50. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What insertion torque is usual?

25 to 45 Ncm is commonly quoted; very high torque risks bone compression necrosis.

Does torque predict stability?

It reflects primary mechanical stability but not the biological osseointegration that follows.
