Resonance frequency analysis (RFA) provides an evaluation of implant stability over time. This analysis is a non-invasive, precise, and objective method. Several studies compare the RFA system with other devices. However, few investigations analyze repeatability and reproducibility between different operators. The aim of this study was to evaluate the intra- and inter-operator concordance of the Osstell® ISQ.
RFA measurements were performed with Osstell® ISQ in a total of 37 implants placed in 21 patients. At the time of implant placement, 6 measurements per implant were taken by three different experienced operators. Three measurements were carried out consecutively and three by removing and placing the SmartPeg-Osstell® to assess intra-operator and inter-operator agreement.
Intra-operator concordance according to the intraclass correlation coefficient (ICC) showed high concordance. The ICC values were higher than 0.9 (p < 0.0001) for consecutive measures and alternative measures, being almost perfect of Landis & Koch classification. For inter-operator concordance The ICC was 0.709 (p < 0.0001) and 0.670 (p < 0.0001) for consecutive and alternative measures, respectively, both estimates being in the substantial category. In torque and ISQ values, no statistically significant differences were observed when operators and measurements were compared.
Osstell® ISQ system was stable both in intra-operator and inter-operator measurements. This device has excellent repeatability and reproducibility, demonstrating reliability to measure the stability of dental implants.
Resonance frequency analysis (RFA) is a non-invasive, objective, and reliable diagnostic method to determine the ideal moment to load the implant, as well as to predict possible failures.
共振频率分析（RFA）可提供随时间推移的植入物稳定性评估。这种分析是一种非侵入性、精确且客观的方法。有几项研究比较了 RFA 系统与其他设备。然而，很少有研究分析不同操作人员之间的可重复性和再现性。本研究旨在评估 Osstell® ISQ 的同内和同外操作者一致性。
在 21 名患者的 37 个植入物中，共进行了 RFA 测量。在植入物放置时，由三位经验丰富的操作员对每个植入物进行了 6 次测量。三次连续进行测量，三次通过移除和放置 SmartPeg-Osstell®进行测量，以评估同内和同外操作者之间的一致性。
根据组内相关系数（ICC），同内一致性显示出高度一致性。ICC 值高于 0.9（p<0.0001），用于连续测量和替代测量，接近 Landis & Koch 分类的完美一致性。对于同外一致性，ICC 分别为 0.709（p<0.0001）和 0.670（p<0.0001），用于连续和替代测量，两个估计均为实质性类别。在扭矩和 ISQ 值方面，当操作员和测量值进行比较时，未观察到统计学差异。
Osstell® ISQ 系统在同内和同外测量中均稳定。该设备具有出色的可重复性和再现性，证明其可靠性可用于测量种植牙的稳定性。
共振频率分析（RFA）是一种非侵入性、客观且可靠的诊断方法，可确定植入物加载的理想时机，并预测可能的失败。
