Long-term studies have documented the successful treatment of edentulous and partially edentulous patients with titanium implants. However, the inability to identify some non-osseointegrated implants before occlusal loading is costly to practitioners and patients. This study followed all patients (n = 40) who had implants placed over a 6-month period. The Periotest instrument was used at Stage II surgery, final impression, prosthesis placement, and 6 and 12 months after occlusal loading to quantify mobility/lack of mobility of implants with conventional 1-piece temporary healing abutments in place. The positive predictive value was 64%. The Periotest instrument was able to identify non-integrated implants only when measured at Stage II surgery and 12 months after occlusal loading, 64% of the time. However, Periotest values recorded at Stage II surgery are not valid predictors of non-osseointegrated implants 12 months post-occlusal loading.
长期研究已证明钛植入物可成功治疗无牙和部分缺牙患者。然而，在咬合加载前无法识别一些未骨整合的植入物，这对从业者和患者来说成本高昂。本研究追踪了在6个月期间植入植入物的所有患者（n = 40）。在二期手术、取最终印模、安装假体以及咬合加载后6个月和12个月时，使用Periotest仪器对安装了传统一体式临时愈合基台的植入物的移动性/无移动性进行量化。阳性预测值为64%。Periotest仪器仅在二期手术时以及咬合加载后12个月测量时，有64%的时间能够识别未整合的植入物。然而，二期手术时记录的Periotest值并不是咬合加载后12个月时未骨整合植入物的有效预测指标。
