Purpose: This study was performed to examine whether different torques to fasten a superstructure with a screw affected mechanical mobility of IMZ implants with intramobile connector (IMC) or titanium element.<BR>Methods: Eight IMZ implants in five patients were used for this study. The same superstructure was fastened with occlusal screw to each implant with IMC or titanium element at 85, 145 and 180 Nmm torque values using a torque wrench. The horizontal mechanical mobility of each implant was measured three times by the automatic diagnostic system for tooth mobility.<BR>Results: The larger the torque values were, the smaller mechanical mobility of IMZ implants with IMC was. Friedman test indicated that mechanical mobility of IMZ implants with IMC significantly changed according to torque values (p<0.01). However, changes in mechanical mobility of the implants with titanium element were not statistically significant. At the fastening torque of 85 and 145 Nmm, a difference in mechanical mobility between implants with IMC and titanium element was statistically significant (p<0.05). However, fastening torque of 180Nmm did not show significant difference.<BR>Conclusions: A superstructure fastened with occlusal screw at torque values of 85 and 145Nmm had little influence on the stress absorption effect of IMC under horizontal load.
