Background: Primary stability has a relevant role in the long‐term success of dental implants. A quantitative method for the measurement of implant stability has been introduced (resonance frequency analysis RFA]). Information about the significance of RFA measurements and about the relationship between RFA values and their association with implant osseointegration, success, or failure is important from a clinical point of view. Purpose: The aim of the present histological and histomorphometric study was to see if a correlation existed between the bone‐implant contact (BIC) percentage of retrieved human implants and RFA values. Materials and Methods: Seven implants inserted in the posterior mandible, with a sandblasted and acid‐etched surface and retrieved after a 6‐month period, were evaluated in the present study. These seven implants had been retrieved for different causes. All these implants were submerged and were retrieved with a 5‐mm trephine bur and immersed in 10% buffered formalin to be processed for histology. Results: A statistically significant correlation could be detected between implant stability quotient and BIC ( p =.016). Conclusions: Even if the relationship between bone structure and RFA is still not fully understood, in our study, a statistically significant correlation was found between RFA and BIC values. Further studies are needed to evaluate a correlation of RFA and BIC in human implants retrieved after a range of healing periods.
