This report presents one-year clinical evaluation data from 120 ceramic and titanium cylindrical and titanium blade-type implants placed in the mandibles of 30 adult dogs. Ninety-six of the implants supported fixed bridges. The bone and gingival health was evaluated by the following indices: crevicular fluid volume index; gingival bleeding index; plaque accumulation index; clinical mobility index; and a quantitative mobility index utilizing the Periotest instrument. Results from this investigation suggest that, overall, the ceramic implants exhibited more fractures and had more mobile implants than did the titanium implant systems. Overall, complete one-year clinical evaluation data demonstrate healthy tissue responses to 112 of the 120 implants. Further, the Periotest instrument appears to offer a more quantitative assessment of clinical mobility. Also, it appears that the clinical evaluation protocol utilized in this study is a valid procedure to use for the assessment of clinical serviceability.
本报告展示了将120颗陶瓷和钛制圆柱形及钛制叶片型种植体植入30只成年犬下颌骨后的一年临床评估数据。其中96颗种植体支持固定桥修复。通过以下指标评估骨和牙龈健康状况：龈沟液量指数；牙龈出血指数；菌斑堆积指数；临床动度指数；以及使用牙周探测仪的定量动度指数。本次调查结果表明，总体而言，陶瓷种植体比钛种植体系统出现更多骨折且种植体动度更大。总体而言，完整的一年临床评估数据显示，120颗种植体中有112颗呈现健康的组织反应。此外，牙周探测仪似乎能对临床动度进行更定量的评估。而且，本研究中使用的临床评估方案似乎是用于评估临床适用性的有效程序。
