Purpose: The purpose of this study was to evaluate the preload maintenance of the retaining screw when using anaerobic sealing agents in implant fixture and abutment components. Specifically, the study examines the effects of anaerobic sealing agents on different types of screws.

Materials and methods: External hexagon implants made of titanium and anti-rotational abutments were used. Titanium abutment screws and ebony abutment screws from the same manufacturer were used. The experiment was divided into four groups (n = 10 in each group). In the control group, no sealing agent was used at the implant fixture and abutment screw interface. All abutment screws were tightened according to the manufacturer's recommended torque (30 N.cm). After 24 hours, the removal torque (detorque) of each screw was measured using a digital torque gauge device. The data were analyzed by two-way ANOVA test according to normality distribution satisfaction.

Results: Looking at the results for each group, titanium screws and no treatment showed detorque values of 20.3 ¡¾ 1.6 N.cm. titanium screws and applied anaerobic sealing agent showed detorque values of 32.4 ¡¾ 6.7 N.cm. Ebony screws and no treatment showed detorque values of 20.2 ¡¾ 1.5 N.cm. ebony screws and applied anaerobic sealing agent showed detorque values of 30.4 ¡¾ 4.5 N.cm.

Conclusion: The detorque value was higher in the case of using anaerobic sealing agents in both the titanium screw and ebony screw groups. But there was no difference between the two screws.
