Implant stability is critical for successful osseointegration. The timing of implant placement may influence both primary and secondary stability; however, limited observational data integrate biomechanical and biological parameters such as insertion torque and marginal bone loss. To compare implant stability between immediate and delayed implant placement using resonance frequency analysis and to assess insertion torque and marginal bone loss over six months. A prospective observational study was conducted among fifty patients receiving single-tooth implants. Implant stability was assessed at placement and at nine, nineteen, and twenty-five weeks. Insertion torque was recorded at placement, and marginal bone loss was evaluated radiographically at baseline, three months, and six months. Delayed implants demonstrated significantly higher stability at all time points (p < 0.05). Mean insertion torque was greater in delayed implants (53.0 ± 16.2 Ncm) than immediate implants (34.0 ± 2.1 Ncm) (p < 0.05). Marginal bone loss remained within clinically acceptable limits in both groups. Delayed placement showed superior stability, while immediate placement achieved functional stability by six months. Combined assessment using resonance frequency analysis, insertion torque, and marginal bone loss supports individualized loading protocols.
