Superior_dental_plexus
The superior dental plexus is a nerve plexus that innervates the upper/maxillary teeth and as adjacent structures.[1] It is formed by the anterior superior alveolar nerve (ASAN), middle superior alveolar nerve (MSAN), and the posterior superior alveolar nerve (PSAN).[1][2][3] It issues dental branches and gingival branches.[4]
A cadaveric study found the plexus to be situated in the alveolar process of the maxilla.[5]
