Theposterior superior alveolar artery (posterior dental artery) is a branch of themaxillary 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 thegingiva.[2]
The artery typically arises frommaxillary artery within thepterygopalatine fossa. It frequently arises in conjunction with theinfraorbital artery.[2]
It passes inferior-ward upon theinfratemporal surface of maxilla before ramifying.[2]
It emits branches that pass through foramina on the posterior aspect of themaxilla alongside theposterior superior alveolar nerves.[1]
Some branches enter thealveolar canals to supply the uppermolar andpremolar teeth as well as themaxillary sinus and adjacent bone.[2]
Some branches pass anterior-ward[citation needed] across thealveolar process to supply thegingiva.[2]
