The aim of this in-vitro study was to compare the physical properties of three suture materials used in periodontal surgery: silk, expanded polytetrafluoroethylene (e-PTFE), and polylactic acid/polyglycolic and (PLA/PGA). Five physical tests were carried out on each of the three suture materials: strain to failure, tensile strength, knot tensile strength, knot slippage, and capillarity. For each test, 30 samples of each suture material were used. In all cases, the statistical results showed that the e-PTFE and the PLA/PGA threads were superior.
丝线、膨体聚四氟乙烯（e-PTFE）和聚乳酸/聚乙醇酸共聚物（PLA/PGA）。对这三种缝合材料分别进行了五项物理测试：断裂应变、拉伸强度、结拉伸强度、结滑动和毛细作用。每项测试均使用每种缝合材料的30个样本。在所有情况下，统计结果表明e-PTFE和PLA/PGA线更具优势。
