目的
本研究旨在调查上颌窦壁血管管的患病率和过程，并使用锥形束计算机断层扫描（CBCT）测量窦底，无牙槽嵴和血管管之间的距离。
材料和方法
对250例拟行种植手术患者的上颌窦CBCT扫描进行了检查。在CBCT图像上观察血管管或切迹的垂直和内外侧位置。使用种植体植入诊断模板确认每颗牙齿的位置。进行统计分析，以验证平均动脉位置是否根据每个牙齿位置，性别和年龄有显着差异。
结果
52.8%的患者观察到上颌动脉骨内吻合。上颌窦底至血管管的垂直距离在第一磨牙区最短（7.58 ± 3.19 mm），在第一前磨牙区最长（9.2 ± 3.22 mm）。牙槽嵴至血管管的距离在第一磨牙区最短（14.79 ± 4.04 mm），在第一前磨牙区最长（18.92 ± 4.86 mm）。这些距离根据牙齿位置而显著不同。从牙槽嵴和窦底到血管管的平均距离不随年龄的增长而减少。根管的内外侧位置也因牙齿位置的不同而显着不同。
结论
通过CBCT获得的关于后上级牙槽动脉分支的信息，种植体植入期间不必要的出血应该更容易预防。建议在窦底提升术前使用CBCT作为常规程序。
PURPOSE
This study was designed to investigate the prevalence and course of the vascular canals in the maxillary sinus walls and to measure the distance between the sinus floor, the edentulous alveolar crest, and the vascular canal using cone beam computed tomography (CBCT).
MATERIALS AND METHODS
The maxillary sinus CBCT scans of 250 patients scheduled for implant surgery were examined. The vertical and mediolateral positions of the vascular canals or notches were investigated on the CBCT images. The location of each tooth was confirmed using a diagnostic template for implant placement. Statistical analyses were performed to verify whether the mean artery position was significantly different according to each tooth location, gender, and age.
RESULTS
A maxillary arterial endosseous anastomosis was observed in 52.8% of patients. The mean perpendicular distance from the sinus floor to the vascular canal was shortest in the first molar region (7.58 ± 3.19 mm) and longest in the first premolar region (9.2 ± 3.22 mm). The mean distance from the alveolar crest to the vascular canal was shortest in the first molar region (14.79 ± 4.04 mm) and longest in the first premolar region (18.92 ± 4.86 mm). These distances were significantly different according to tooth position. The mean distances from the alveolar crest and the sinus floor to the vascular canal did not decrease with age. The mediolateral position of the canals was also significantly different depending on tooth position.
CONCLUSION
With this information about the branch of the posterior superior alveolar artery from CBCT, unnecessary bleeding during implant placement should be more easily preventable. The use of CBCT is recommended as a routine procedure prior to sinus floor elevation.
