To 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.
A 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.
The 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.
The TLC is higher for vertical mattress sutures than for interrupted sutures, and it increases when the insertion points are farther from the wound margin.
确定不同距创缘插入点的间断缝合和垂直褥式缝合的拉伸载荷能力（TLC）和撕裂特性，以及使用垂直褥式缝合时的咬合力大小的影响。
从猪颌骨中获取的总共 120 个牙龈和衬里黏膜样本根据缝合技术（间断缝合和垂直褥式缝合）、插入点距创缘的距离（边缘、1、3 和 5mm）和咬合力大小（1、3 和 5mm）进行分组。使用拉伸试验机装置评估缝线的 TLC 和撕裂特性。
无论插入点距创缘的距离如何，垂直褥式缝线的 TLC 均明显高于间断缝线（组间 p<0.001）。该距离显著影响垂直褥式缝线的 TLC（p<0.05），但不影响间断缝线（p>0.05）。撕裂特性测试表明，当插入点距创缘超过 3mm 时，各组均未发生组织撕裂。
垂直褥式缝线的 TLC 高于间断缝线，并且当插入点距创缘越远时，TLC 增加。
