The prospective study compares, in split-mouth design, the use of two different suture materials, silk vs. Teflon-coated, multi-filament braided polyester threads suture.
Ten edentulous or partially edentulous patients were surgically treated for implant installation. Each side was sutured with either, randomly selected one or the other suture material. Seven days postsurgically, the sutures were removed and three knots per patient and side were collected for microbiological testing. Additionally, a piece of each suture thread was analysed before clinical use to test its susceptibility for bacterial adherence. To evaluate the patient's subjective opinion, a questionnaire based on Visual Analogue Scale had to be filled out by all included patients 1 week after the intervention.
The results showed a more pronounced plaque accumulation for silk sutures but there was not a statistical difference. The intraoperative handling of the silk sutures was less comfortable and the patient comfort was worse than Teflon-coated polyester suture.
The bacterial adherence on Teflon-coated polyester suture was slightly inferior than silk suture although it did not show the expected differences.
本前瞻性研究采用分口设计，比较了两种不同缝线材料的使用效果，即丝线与聚四氟乙烯涂层多股编织聚酯缝线。
10 名无牙或部分无牙患者接受了种植体植入手术。每侧随机选择一种缝线材料进行缝合。术后 7 天，拆除缝线，并从每位患者和每侧收集 3 个结进行微生物检测。此外，在临床使用前，分析了每根缝线的一部分，以测试其对细菌黏附的易感性。为了评估患者的主观意见，所有纳入的患者在干预后 1 周内需要填写一份基于视觉模拟量表的问卷。
结果显示，丝线缝线的菌斑积累更为明显，但无统计学差异。丝线缝线的术中操作舒适性较差，患者舒适度也不如聚四氟乙烯涂层聚酯缝线。
尽管聚四氟乙烯涂层聚酯缝线的细菌黏附性略低于丝线缝线，但并未显示出预期的差异。
