Objective: The aim of this study was to assess the correlation between the peri-implant bone density and the biological stability around dental implants. Materials and Methods: A total of 56 implants were placed in the mandibular canine area of 28 patients to retain mandibular overdentures. The assessment of bone density changes was obtained through Cone-Beam Computed Tomography (CBCT) and the assessment of implant stability was obtained through Resonance Frequency Analysis (RFA) at loading time, and after 6, 12, 24 months. Results: RFA measurement showed a mean of 67.5± 5.8 ISQ at loading time and a mean of 71.3±5.5 ISQ after 24 months. Bone density around the implants showed a mean of 683.48±78.63 HU at loading time, and a mean of 722.24±58.4 HU after 24 months. These increases were statistically significant (p˂0.05). Conclusion: The biological implant stability as measured using the Resonance Frequency Analysis (RFA) and the peri-implant bone density as measured using Cone Beam Computed Tomography (CBCT) showed a significant moderate positive correlation.
