Superior alveolar artery

Overview
The superior alveolar artery is a branch of the maxillary artery that serves the upper teeth and other related structures.

The superior alveolar artery branches off of the maxillary artery in the pterygopalatine fossa. It descends to the maxilla where it gives off branches that supply the molar and premolar teeth, the maxillary sinus, and the gingivae. The superior alveolar artery divides into the posterior superior alveolar artery and the anterior superior alveolar artery.
