The purpose of the present study was to investigate the intraobserver and interobserver reliability of 3 resonance frequency analysis (RFA) devices and to compare the implant stability quotient (ISQ) values according to implant macro design and diameter in 2 different bone densities. A total of 64 implants (Neoss ProActive; Neoss; Harrogate, UK) of varying diameters (3.5 and 4.0 mm) and implant macro design (tapered and straight) were placed in 2 artificial bone blocks (the density of type 2 and 3). The implant primary stability was measured using Osstell IDx (Osstell; Göteborg, Sweden), Osstell Beacon and Penguin RFA (Integration Diagnostics; Göteborg, Sweden). The ISQ value of each implant was measured by 2 observers and recorded 5 times in 2 directions. The intraobserver and interobserver reliability of RFA devices were evaluated. In addition to that, mean ISQ values were calculated for each RFA device to evaluate the effect of implant diameter, implant macro design, and bone density on ISQ values. ISQ values were significantly higher for implants placed within the type 2 bone than for the type 3 bone. The 4.0-mm diameter implants presented higher ISQ values than 3.5-mm diameter implants. The intraclass correlation coefficient (ICC) values for intraobserver reliability were above 0.85 for each observer and the ICC values for interobserver reliability were 0.94, 0.93, and 0.98 for Osstell IDx, Osstell Beacon, and Penguin RFA, respectively. Although there was excellent interobserver reliability with 3 RFA devices, the intraobserver reliability of Osstell Beacon and Penguin RFA were slightly better than Osstell IDx. Bone density and implant diameter were parameters affecting the primary stability of implants.
本研究旨在探讨 3 种共振频率分析（RFA）设备的观察者内和观察者间可靠性，并比较不同种植体宏观设计和直径在 2 种不同骨密度下的种植体稳定性指数（ISQ）值。共将 64 枚直径（3.5 和 4.0mm）和种植体宏观设计（锥形和直形）不同的 Neoss ProActive 种植体（Neoss；英国哈罗盖特）植入 2 个人工骨块（密度为 2 型和 3 型）中。使用 Osstell IDx（Osstell；瑞典哥德堡）、Osstell Beacon 和 Penguin RFA（Integration Diagnostics；瑞典哥德堡）测量种植体的初始稳定性。由 2 名观察者测量每个种植体的 ISQ 值，并在 2 个方向上记录 5 次。评估 RFA 设备的观察者内和观察者间可靠性。此外，还计算了每个 RFA 设备的平均 ISQ 值，以评估种植体直径、种植体宏观设计和骨密度对 ISQ 值的影响。植入物在 2 型骨中的 ISQ 值明显高于 3 型骨。4.0mm 直径的种植体比 3.5mm 直径的种植体具有更高的 ISQ 值。每位观察者的观察者内可靠性的组内相关系数（ICC）值均高于 0.85，而 Osstell IDx、Osstell Beacon 和 Penguin RFA 的观察者间可靠性的 ICC 值分别为 0.94、0.93 和 0.98。尽管 3 种 RFA 设备具有出色的观察者间可靠性，但 Osstell Beacon 和 Penguin RFA 的观察者内可靠性略优于 Osstell IDx。骨密度和种植体直径是影响种植体初始稳定性的参数。
