The posterior superior alveolar artery (posterior dental artery) is given off from the maxillary, frequently in conjunction with the infraorbital artery just as the trunk of the vessel is passing into the pterygopalatine fossa.
|Posterior superior alveolar artery|
|Branches||branches to alveolar canals |
branches to gingiva
|Supplies||molar and premolar teeth |
lining of the maxillary sinus
|Latin||arteria alveolaris superior posterior|
Descending upon the tuberosity of the maxilla, it divides into numerous branches, it descends on the posterior surface of the maxilla and gives branches that supply the molar and premolar teeth and the lining of the maxillary sinus, while others are continued forward on the alveolar process to supply the gingiva.
