Evaluation of insertion torque and implant stability using the osstell device according to connection method and practitioner variability

Abstract

Purpose: This study aimed to evaluate the effects of SmartPeg connection methods and practitioner-related variability on insertion torque and implant stability measurements using the Osstell device. Materials and Methods: Four oral and maxillofacial surgeons each placed 40 implants into bovine femur bone blocks with D1 bone quality. The study was conducted at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Hatay Mustafa Kemal University (Hatay, Türkiye). SmartPeg insertion torque was measured using a digital torque wrench. Resonance Frequency Analysis (RFA) was performed immediately after SmartPeg placement. Data were analyzed using ANOVA and Intraclass Correlation Coefficient (ICC). Results: The mean insertion torque values were 69.88 ± 2.11 Ncm for the group with lower applied torque, 81.66 ± 1.43 Ncm for the group with higher manual torque, and 80.88 ± 1.55 Ncm for the standardized angulated adapter group. Statistically significant differences were observed among the groups. The highest intergroup consistency was recorded between the manual high-torque group and the angulated adapter group (ICC = 0.655, 95% CI: 0.045–0.955, p = 0.026). Additionally, ISQ values showed a positive correlation with torque consistency, suggesting that uniform application methods may enhance measurement reliability. Conclusion: Practitioner-related variability affects SmartPeg insertion torque and subsequent ISQ measurements. The use of a standardized connection method, such as an angulated adapter applying fixed torque, may improve the reliability and reproducibility of RFA-based implant stability assessments.
