The aim of this anatomical study was to measure the distance from the intraosseous and extraosseous arterial anastomoses of the maxillary sinus to the alveolar ridge in edentulous specimens dissected from human cadavers.
Forty edentulous maxillary specimens were dissected, anatomically prepared, and injected for a better visualization of the maxillary sinus artery.
This study showed that the mean distance from the alveolar ridge to the extraosseous anastomosis was 16 mm for the second maxillary molar, 12 mm for the first maxillary molar, and 13 mm for the second maxillary premolar. For the intraosseous anastomosis to the alveolar ridge, the mean distance was 17 mm for the second maxillary molar, 13 mm for the first maxillary molar, and 14 mm for the second maxillary premolar.
Under the conditions of this study, we found that the mean distance from the alveolar crest to the extraosseous anastomosis and intraosseous anastomosis was shortest for the first maxillary molar and second maxillary premolar and greatest for the second maxillary molar.
These findings provide data whose relevance for clinical dentistry is that they can be applied to minimize the risk of damage to the arterial network of the maxillary sinus during surgical procedures in this region.
本解剖学研究旨在测量从人类尸体上解剖的无牙颌标本中上颌窦的骨内和骨外动脉吻合口到牙槽嵴的距离。
解剖40个无牙颌上颌标本，进行解剖学处理，并进行注射以更好地观察上颌窦动脉。
本研究表明，从牙槽嵴到骨外吻合口的平均距离，上颌第二磨牙为16毫米，上颌第一磨牙为12毫米，上颌第二前磨牙为13毫米。从骨内吻合口到牙槽嵴的平均距离，上颌第二磨牙为17毫米，上颌第一磨牙为13毫米，上颌第二前磨牙为14毫米。
在本研究条件下，我们发现从牙槽嵴到骨外吻合口和骨内吻合口的平均距离，上颌第一磨牙和上颌第二前磨牙最短，上颌第二磨牙最长。
这些发现提供的数据与临床牙科的相关性在于，它们可用于在该区域的外科手术中尽量降低对上颌窦动脉网络造成损伤的风险。
