Fig. 6From: A comparison of bone conductivity on titanium screws inserted into the vertebra using different surface processingResults of biomechanical examination (maximum torque value). At 4 and 8 weeks after screw insertion, the maximum torque value of the AO-Ti and I-Ti groups was significantly higher than that of the Ti group (p < 0.05). There was no significant difference found between the AO-Ti and I-Ti groupsBack to article page
