The posterior superior alveolar artery, a branch of the maxillary artery that serves the upper teeth and other related structures The anterior superior alveolar artery, a branch of the infraorbital artery, also supplying the upper teeth and related structures The middle superior alveolar artery, an inconstant branch of the infraorbital artery that forms anastomoses with the other two superior alveolar arteries
