Anterior superior alveolar nerve

The anterior superior alveolar branch (anterior superior dental branch), of considerable size, is given off from the maxillary nerve (the second branch of the trigeminal nerve or cranial nerve V, abbreviated V2) just before its exit from the infraorbital foramen; it descends in a canal in the anterior wall of the maxillary sinus, and divides into branches which supply the incisor and canine teeth.
