Methods: In this study, 58 implants were placed in twenty-nine (16 male, 13 female). Implant Stability Quotient (ISQ) values were measured by RFA device (Osstell Mentor) at implant placement and at 1., 2., 4., 6., 8 weeks. Data were analyzed for different healing times, in relation to implant body surface area (IBSA) (110, 138, 143, 167,174, 215 mm2 ).
Results: Only difference in ISQ values at the time of implant placement between mandibula and maxilla was observed in 110 and 174 mm2 IBSA . There were no statistical differences in ISQ values in different implant body surface areas between any time points, however, there was a statistically significant reduction (p<0,05) at weeks 4 and 6 compared to the time of implant placement in 174 mm2 IBSA .
Conclusion: It can be concluded that the IBSA does not effect ISQ values of implants at different time points. ISQ values of implants placed in mandibula stays more stable than maxilla which could be due to the type of bone and the bone quality. Implants placed in mandibula might be more suitable for immediate loading than the ones placed in maxilla. However, further studies are needed to confirm these results.
