The clinical study's main goal was to determine the frequency of peri-implant inflammation and changes in the marginal bone level around dental implants with single-unit fixed dental prostheses (FDP) and the teeth next to them, in relation to the horizontal and vertical implant positions. Materials & Method: After following a conventional drilling procedure, internal hex implants were inserted at healed sites. RFA measurements were taken using the Osstell_ Mentor immediately following implant placement (primary ISQ) and postoperatively at 2, 3, 4, 5, 6, 9, 12, 18, and 24 months. After implant insertion and at postoperative 4, 7, 10, 12, 18, and 24 months, periapical radiographs were performed to assess marginal bone loss (MBL). Results: The IT of various bone kinds indicated significant variances. Implants positioned in locations with bone density of D1 or D2 had considerably higher IT than those positioned in D3 or D4 regions. 63 implants had bone loss of less than 1 mm, 21 implants lost bone of less than 1 mm, and 6 implants lost bone of more than 2 mm. The most significant bone loss measured 2.68 mm. Only three of the implants—out of the six with bone loss greater than 2 mm—presented with BOP. Discussion & Conclusion: Utilizing insertion torque and resonance frequency analysis, clinical testing of implant stability is simple to carry out. The findings of this study imply that bone density and implant diameter were important factors in determining IT/primary ISQ. Primary ISQ had less of an effect on MBL than bone density and IT.
