Anatomical terminology |
The posterior superior alveolar artery (posterior dental artery) is a branch of the maxillary artery.[1][2] It is one of two or three superior alveolar arteries. It provides arterial suply to the molar and premolar teeth, maxillary sinus and adjacent bone, and the gingiva.[2]
The artery typically arises from maxillary artery within the pterygopalatine fossa. It frequently arises in conjunction with the infraorbital artery.[2]
It passes inferior-ward upon the infratemporal surface of maxilla before ramifying.[2]
It emits branches that pass through foramina on the posterior aspect of the maxilla alongside the posterior superior alveolar nerves.[1]
Some branches enter the alveolar canals to supply the upper molar and premolar teeth as well as the maxillary sinus and adjacent bone.[2]
Some branches pass anterior-ward[citation needed] across the alveolar process to supply the gingiva.[2]
