The present retrospective study aimed to determine the relationship between the secondary implant stability quotient and different parameters related to an oxidized implant.
A total of 135 patients (305 oxidized implants) were included. Implant-related factors (length, diameter, surgical and loading protocols, grafting, insertion torque, and primary stability) were used for comparisons and linear regression analyses, using secondary ISQ as the dependent variable.
At the patient level, the mean time from implantation to secondary ISQ registration was 20.3 ± 29 weeks, and the mean secondary ISQ was 77.30 ± 7.22. The ISQ did not reveal significant differences regarding implant lengths, loading protocol, and simultaneous grafting. In contrast, platform diameters (3.5, 4.3, and 5.0), surgical protocols (one stage versus two stages), insertion torque (<35 Ncm versus >35 Ncm), and primary stability (achieved versus not achieved) all revealed significant secondary ISQ differences. Nevertheless, the regression analysis demonstrated that the platform diameter was the only variable significantly and positively predicted the secondary ISQ. Similar findings were found with the implant level analysis.
Among different implant- and protocol-related parameters, the platform diameter of the oxidized implant appears to be the only significant predictor of high secondary ISQ values at the time of superstructure connection.
本回顾性研究旨在确定二次种植体稳定性商数与氧化种植体相关的不同参数之间的关系。
共纳入135例患者（305颗氧化种植体）。以二次种植体稳定性商数作为因变量，将种植体相关因素（长度、直径、手术及加载方案、植骨、植入扭矩和初期稳定性）用于比较和线性回归分析。
在患者层面，从种植到记录二次种植体稳定性商数的平均时间为20.3±29周，二次种植体稳定性商数的平均值为77.30±7.22。种植体稳定性商数在种植体长度、加载方案和同期植骨方面未显示出显著差异。相比之下，平台直径（3.5、4.3和5.0）、手术方案（一期与二期）、植入扭矩（<35 Ncm与>35 Ncm）和初期稳定性（实现与未实现）均显示出二次种植体稳定性商数的显著差异。然而，回归分析表明，平台直径是唯一能显著且正向预测二次种植体稳定性商数的变量。在种植体层面分析中也发现了类似的结果。
在不同的种植体及方案相关参数中，氧化种植体的平台直径似乎是上部结构连接时二次种植体稳定性商数高值的唯一重要预测指标。
