Fig. 4From: Implant-abutment screw removal torque values between customized titanium abutment, straight titanium abutment, and hybrid zirconia abutment after a million cyclic loading: an in vitro comparative studyComparison of the mean removal torque value between types of abutments at 0 cycle (initial), 50,000 cycles, and 1,000,000 cycles. The zero-cycle group is significantly higher than other groups. (P-value < 0.001)Back to article page
