Resonance frequency analysis (RFA) requires abutment disconnection to monitor implant stability. To overcome this limitation, an experimental transepithelial abutment was designed to allow a SmartPeg to be screwed onto it, in order to determine the prototype abutments repeatability and reproducibility using Osstell ISQ and to assess whether implant length and diameter have an influence on the reliability of these measurements. RFA was conducted with a SmartPeg screwed directly into the implant and onto experimental abutments of different heights of 2, 3.5 and 5 mm. A total of 32 patients (116 implants) were tested. RFA measurements were taken twice for each group from mesial, distal, buccal and palatal/lingual surfaces. Mean values and SD were calculated and Intraclass Correlation Coefficients (ICC) ( < 0.05, IC 95%). The implant stability quotient (ISQ) mean values were 72.581 measured directly to implant and 72.899 (2 mm), 72.391 (3.5 mm) and 71.458 (5 mm) measured from the prototypes. ICC between measurements made directly to implant and through 2-, 3.5- and 5-mm abutments were 0.908, 0.919 and 0.939, respectively. RFA values registered through the experimental transepithelial abutments achieved a high reliability. Neither the implant length nor the diameter had any influence on the measurements' reliability.
共振频率分析（RFA）需要将基台断开以监测种植体稳定性。为了克服这一限制，设计了一种实验性的上皮下基台，允许将 SmartPeg 拧入其中，以便使用 Osstell ISQ 来确定原型基台的重复性和再现性，并评估种植体长度和直径是否会影响这些测量的可靠性。RFA 是将 SmartPeg 直接拧入种植体并拧到高度分别为 2、3.5 和 5mm 的实验基台上进行的。共测试了 32 名患者（116 个种植体）。每个组的近中、远中、颊侧和腭/舌侧表面均进行了两次 RFA 测量。计算平均值和标准差，并计算组内相关系数（ICC）（<0.05，IC95%）。直接测量种植体的种植体稳定性值（ISQ）平均值为 72.581，通过 2mm、3.5mm 和 5mm 基台测量的 ISQ 平均值分别为 72.899、72.391 和 71.458。直接测量种植体与通过 2mm、3.5mm 和 5mm 基台测量的 ICC 分别为 0.908、0.919 和 0.939。通过实验性上皮下基台记录的 RFA 值具有很高的可靠性。种植体长度和直径均不影响测量的可靠性。
