Objective: The aim of this study is to investigate the in vitro effects of improper implant insertion on the primary stability. Material and Methods: 75 dental implants were inserted 1.5 mm above the 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 periotest measurements were repeated. The differences between 2 measurements for 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 to be significantly higher than that of the improperly inserted implants both in terms of ISQ and periotest values (p<0.01). Conclusion: The findings of this in vitro study indicate that it is impossible to achieve perfect primary stability with implants in cases where they are improperly inserted in their recipient sites. As such, a drawback is most likely to occur when flapless surgery is preferred, it may therefore be advised to adopt more accurate and precise techniques.

Amaç: Bu çalışmanın amacı; tam olarak yerleştirilmeyen implantların primer stabiliteye olan in vitro etkilerinin incelenmesidir. Gereç ve Yöntemler: Beş adet dana kaburgası üzerine 75 dental implant kret seviyesinden 1,5 mm yukarıda olacak şekilde yerleştirilmiştir. Bu aşamada implantların rezonans frekans analizi (RFA) ve periotest değerleri ölçülmüştür. Daha sonra implantlar tamamen yerleştirilmiştir. RFA ve periotest değerleri ölçümleri tekrarlanmıştır. RFA ve periotest ölçümlerinin 2 değeri arasındaki farklar bağımlı örneklem t testi ile istatistiksel olarak incelenmiştir. ISQ ve periotest değerleri arasındaki korelasyon p<0.05 önemlilik düzeyinde Pearson korelasyon testi ile incelenmiştir. Bulgular: Tam yerleştirilmiş implantların primer stabilitesinin hem ISQ hem de periotest değerleri bakımından uygun yerleştirilmeyen implantlara göre anlamlı olarak daha yüksek olduğu bulunmuştur (p<0,01). Sonuç: Bu in vitro çalışmadan elde edilen bulgulara dayanarak, implantların yuvalarına tam olarak yerleştirilmediği durumlarda primer stabilitenin tam olarak elde edilemeyeceği görülmektedir. Flepsiz cerrahi tercih edildiğinde, bu durumla kolaylıkla karşılaşılabileceği için daha hassas ve net yöntemler kullanılması tavsiye edilebilir.
