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.
对CeraOne和EsthetiCone种植体系统的负载疲劳性能进行了研究。使用三种扭矩（标准扭矩、标准扭矩+20%和标准扭矩-20%）来拧紧螺钉。采用旋转梁疲劳模型。以与长轴呈30度角的方式对样本施加70牛的负载。双向方差分析显示：（1）每个系统的三种扭矩之间无统计学显著差异；（2）种植体系统之间存在统计学显著差异。15个CeraOne样本中有10个发生种植体失败。在EsthetiCone系统中，仅发生基台螺钉失败。
