Posterior superior alveolar artery
The posterior superior alveolar artery (posterior dental artery) is a branch of the maxillary artery. It emits branches that pass through foramina on the posterior aspect of the maxilla alongside the posterior superior alveolar nerves.[1]

Anatomy
Origin
The artery arises from maxillary artery as it is passing into the pterygopalatine fossa. It frequently arises conjunction with the infraorbital artery.
Branches
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.
