J Clin Periodontol:氧化锆种植体

这项长期前瞻性队列研究的3年期报告旨在评估一次性用氧化锆口腔种植体单一牙齿替换的临床和影像学结果。

这项长期前瞻性队列研究的3年期报告旨在评估一次性用氧化锆口腔种植体单一牙齿替换的临床和影像学结果。

65名患者接受即刻一期种植手术。植入后1年,3年后采用标准化X光片监测种植体周围骨水平。采用单因素分析不同基线参数对种植体植入36个月时边缘性骨吸收的相关因素。软组织参数在植入后6个月,1年后和3年随访时进行评估。3年后,6个后牙位种植体脱落,累计存活率达到90.8%。平均边缘骨吸收是1.45毫米; 35%的种植体骨吸收至少2毫米,22%超过3毫米。单因素分析没有确定任何与边缘性骨丢失有关的参数。3年后探诊深度,临床附着水平,出血指数增加,菌斑指数下降。

结论:所提供的陶瓷种植体的低存活率,特别是高频骨吸收是显而易见的,但原因仍然不明。
