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 study

Abstract Purpose The objective of this research was to determine removal torque values after mechanical cyclic loading and bending moment after the static compression testing of customized titanium abutment compared to prefabricated and hybrid abutments. The sixty implants were divided into three groups equally: Straight titanium abutment group, Customized titanium abutment company, and the Hybrid zirconia abutment group. Results The mean initial removal torque value was much higher than 50,000 cycles and 1,000,000 cycles, and all abutment bending times were not significantly different. After the fatigue test, it could be concluded from the boundary of this in-vitro study that customized titanium abutment and hybrid abutment were not significantly different in terms of removal torque values. It could be further stated that the abutment type has no effect on abutment stability or fracture strength.
