Table 7. Bending of implant neck and torque around stem.
HIGH100 data at the instance of peak force Fres. Mbn = bending moment at base of neck (Fig 1) without friction, only caused by Fres. Mts = torque around stem without friction. Mbs = bending moment in stem without friction. ΔMbn, ΔMts and ΔMbs = changes due to additionally acting friction moments at head. ISO Neck/Stem = ISO 7206-6/4 test forces.
