Figure 8

Comparison of the torque (a) and number of cycles (b) required to achieve 2, 4, 6, 8, and 10 degrees of torsion of the compression screws (DCP fixation) with square threads and triangle threads under cyclic torsional loading. Mean values ± standard deviation of the measured values are presented (N = 5) (Student’s t-test, *p < 0.05, **p < 0.01).
