Objective: The aim of this study is to investigate the invitro effects of improper implant insertion on the primary stability. Material and Methods: 75 dental implants were inserted 1.5 mm abovethe crestal level on 5 bovine bone ribs. At this stage, resonance frequency analysis (RFA) and periotest values were measured. Subsequently, the implants were fully placed. RFA and periotestmeasurements were repeated. The differences between 2 measurementsfor RFA and periotest was statistically analyzed with paired sample ttest. The correlation between the ISQ and periotest values were analyzed using Pearson correlation test at a significance level of p<0.05.Results: The primary stability of fully installed implants were found tobe significantly higher than that of the improperly inserted implantsboth in terms of ISQ and periotest values (p<0.01). Conclusion: Thefindings of this in vitro study indicate that it is impossible to achieveperfect primary stability with implants in cases where they are improperly inserted in their recipient sites. As such, a drawback is most likelyto occur when flapless surgery is preferred, it may therefore be advisedto adopt more accurate and precise techniques
