Aim: The aim of the study was to compare and correlate the primary stabilities of dental implants using torque wrench and resonance frequency analysis (RFA). Materials and Methods: A total of ten patients with partial edentulous condition (Kennedy's Class I, II, and III conditions) in relation to posterior mandibular arch were selected for the study based on inclusion and exclusion criteria. Only the implants positioned in the first molar region were considered for the study (one implant in each patient) to avoid bone density-related bias. Insertion torque values were recorded using a standard spring-loaded torque wrench. RFA at the time of placement was evaluated. Statistical Analysis Used: Linear correlation graph was drawn and statistical analysis was carried out using Mann–Whitney U-test. Results: Statistical analysis between the maximum insertion torque and implant stability quotient (ISQ) values with Mann–Whitney U-test indicated statistical significance (P = 0.0002). Linear correlation graph indicated statistical significance (P = 0.0005; r = 0.8951). Conclusion: Within the limitations of this study, a positive correlation is observed between implant insertion torque and ISQ values measured with RFA.
