Anatomical terminology [edit on Wikidata]

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]

Anatomy

Origin

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

Course

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

Branches

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]
