AimTo determine the tensile load capacity (TLC) and the tearing characteristics for interrupted and vertical mattress sutures with different insertion points from the wound margin, and the effect of the bite size when using vertical mattress sutures.Materials and MethodsA total of 120 gingiva and lining mucosa samples obtained from pig jaws were divided into groups according to the suturing technique (interrupted and vertical mattress sutures), distance of the insertion points from the wound margin (margin, 1, 3, and 5 mm) and bite size (1, 3, and 5 mm). The TLC of the suture and the tearing characteristics were evaluated using a tensile tester device.ResultsThe TLC was significantly higher for vertical mattress sutures than for interrupted sutures regardless of the distance of the insertion points from the wound margin (intergroup p < .001). This distance significantly influenced the TLC for vertical mattress sutures (p < .05) but not for interrupted sutures (p > .05). Testing the tearing characteristics revealed that no tissue tearing occurred in groups when the insertion points were more than 3 mm from the wound margin.ConclusionThe TLC is higher for vertical mattress sutures than for interrupted sutures, and it increases when the insertion points are farther from the wound margin.

间断和垂直床垫缝合中插入点与伤口边缘的距离影响拉伸负载能力：体外实验研究

目的确定伤口边缘不同插入点的间断和垂直床垫缝合线的拉伸负载能力（TLC）和撕裂特性，以及使用垂直床垫缝合线时咬合尺寸的影响。材料和方法总共120个牙龈和衬里从猪颌获得的粘膜样本根据缝合技术（间断缝合和垂直床垫缝合）、插入点距伤口边缘的距离（边缘、1、3和5毫米）和咬合大小（1、3和 5 毫米）。使用张力测试仪装置评估缝合线的 TLC 和撕裂特性。结果无论插入点距伤口边缘的距离如何，垂直床垫缝合线的 TLC 均显着高于间断缝合线（组间）p< .001)。该距离显着影响垂直床垫缝合线的 TLC（p< .05) 但不适用于间断缝合 (p> .05)。撕裂特性测试显示，当插入点距离创面边缘超过3mm时，各组均未发生组织撕裂。结论垂直床垫缝线的TLC高于间断缝合，并且当插入点距离伤口边缘越远时，TLC越高。伤口边缘。
