Work out implant torque instantly with clear inputs, formula shown and shareable results.
Multiplies the applied force by the wrench lever arm to give insertion torque, and works out the force needed to reach a target torque.
Torque
Torque (Ncm) = force (N) x lever arm (cm); 1 Nm = 100 Ncm

25 to 45 Ncm is commonly quoted; very high torque risks bone compression necrosis.
It reflects primary mechanical stability but not the biological osseointegration that follows.
