This study assessed the colonization of Brånemark dental implants by periodontopathic bacteria in four partially edentulous patients with a total of 10 implants. Marginal and subgingival plaque on the implants was sampled 14 days and 28 days after second-stage surgery and compared with plaque from three teeth closest to the implant sites sampled before second-stage surgery (baseline) and at 14 and 28 days. Slot immunoblot assay was used to determine the presence or absence of bacterial antigen to six different periodontopathic microorganisms. In general, colonization of marginal implant plaque occurred within 14 days, whereas subgingival colonization took longer and occurred within 28 days. It appears that Brånemark dental implants placed in partially edentulous patients may be colonized by disease-associated bacteria within 14 days of second-stage surgery.
本研究评估了4例部分牙列缺损患者共10颗种植体上牙周病原菌在Brånemark种植牙上的定植情况。在二期手术后14天和28天采集种植体上的边缘和龈下菌斑，并与二期手术前（基线）以及14天和28天时在距种植位点最近的三颗牙齿上采集的菌斑进行比较。采用狭缝免疫印迹分析法测定6种不同牙周病原菌的细菌抗原的有无。一般来说，种植体边缘菌斑在14天内发生定植，而龈下定植所需时间更长，在28天内发生。似乎在部分牙列缺损患者中植入的Brånemark种植牙在二期手术后14天内可能被疾病相关细菌定植。
