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 supply to the molar and premolar teeth, maxillary sinus and adjacent bone, and the gingiva.[2]

Anatomy

[edit]

Origin

[edit]

The artery typically arises from maxillary artery within the pterygopalatine fossa. It frequently arises in conjunction with the infraorbital artery.[2]

Course

[edit]

It passes inferior-ward upon the infratemporal surface of maxilla before ramifying.[2]

Branches

[edit]

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]
