Introduction: When applying torque to the screw of the prosthetic component, a compressive force develops between the parts, and the screw-implant connection is subject to the effect of settling. The interior of the screw and implant threads are manufactured with irregularities that are smoothed out by the tightening force, causing a loss of 2-10% of the initial torque. Therefore, it is recommended to reapply the torque after 10 minutes. Resonance frequency analysis is the main method for evaluating the long-term stability of implants, and its behavior on intermediate components still raises questions. Objectives: To evaluate whether the effect of settling significantly interferes with the resonance frequency analysis values on the screw of the component. Methodology: Alternating installation of 10 Cone Morse and 10 External Hexagon dental implants in blocks of fresh bovine ribs, selected according to the same bone density. Intermediate components of the mini conical abutment type were installed with torque values of 20 N.cm and 32 N.cm. The Ostell device was used to measure the resonance frequency analysis on the 4 sides of the components, and the average values were considered. After 10 minutes, new measurements were taken. Results: The immediate analysis values on the dental implant components and after 10 minutes were not significantly different. Conclusion: Within the limitations of the study design, it was found that the effect of settling does not interfere with the resonance frequency analysis of the implant's intermediate components.
