背景：种植体手术中口腔底出血是由于舌下间隙动脉损伤引起的。目的：本研究旨在评估种植体手术中相对出血的风险。材料与方法：我们用26具人的尸体调查了颏下和舌下动脉的发生率和直径，并特别参考了它们与这些动脉的走行模式的关系。结果：区分出三种动脉类型：主干动脉（MD）、粘骨膜支（MB）和皮质支（CB）。髓舌骨肌上部中切区MB和CB的发生率明显高，而MB和CB的直径明显小于切区MD的发生率。下颌侧切牙、犬齿和前磨牙区颏下动脉MD的发生率显著高于下颌侧切牙、犬齿和前磨牙区，而上颌第二磨牙和第三磨牙MD的发生率显著低于颏下动脉。结论：在种植手术中，切牙、犬齿、前磨牙和第一磨牙区域的颏下动脉易受损伤。
Background: Bleeding in the floor of the mouth during implant surgery is attributed to arterial injuries in the sublingual space.Purpose: This study aimed to assess the relative hemorrhage risk during implant surgery.Materials and Methods: We investigated the occurrence rate and diameter of submental and sublingual arteries with special reference to their relationship with the course patterns of these arteries using 26 human cadavers.Results: Three types of arteries were distinguished: main duct (MD), mucoperiosteal branches (MB), and cortical branches (CB). The occurrence rate of MB and CB was significantly high at the central incisor region in the upper part of the mylohyoid muscle, whereas the diameter of the MB and CB was significantly smaller than the occurrence rate of MD at the incisor regions. The occurrence rate of MD in the submental artery was significantly higher at the lateral incisor, canine, and premolar regions in the lower parts, whereas the occurrence rate of MD was significantly lower at the second and third molars in the upper parts.Conclusion: The susceptibility of the submental artery to injury is suggested at the incisors, canine, premolars, and first molar regions during implant surgery.
