The objective of this study is to measure the Implant Stability Quotient (ISQ) values of implants at the time of fixture placement and during the healing period to investigate the factors affecting implant stability, which is a crucial predictor of implant success. Materials and Methods: Fifty implants were placed in 39 patients, and the ISQ values were measured using the OStell Mentor device. The ISQ values were measured at the time of fixture placement and 1, 4, 6, 8, and 12 weeks after implant placement. Results: No implant failures occurred during this time period. The changing pattern of ISQ was similar in all the implants, with good primary stability, followed by a decrease from 1 to 4 weeks, an increase after 6 weeks, and relative stability or a slight increase afterward. Within the limitations of this study, it can be concluded that repeated measurements of ISQ values during the healing period have diagnostic benefits.
