Load fatigue performance of two implant-abutment combinations.
The load fatigue performance of the CeraOne and EsthetiCone implant systems was investigated. Three torques (standard torque, standard torque + 20%, and standard torque -20%) were used to tighten the screws. A rotating-beam fatigue model was used. A 70-N load was applied to the specimens at a 30-degree angle to the long axis. Two-way analysis of variance revealed (1) no statistically significant difference between the three torques for each system, and (2) a statistically significant difference between the implant systems. Implant failure occurred in 10 of 15 CeraOne specimens. In the EsthetiCone system, only abutment screw failure occurred.
