The anterior superior alveolar nerve block is used to obtain anesthesia of the maxillary canine and central and lateral incisors.
Injections included anterior superior alveolar nerve block (ASA), middle superior alveolar nerve block (MSA), posterior superior alveolar nerve block (PSA), and right and left inferior alveolar nerve blocks (IANB) using 3 percent mepivacaine during the 90-minute session.
The dentist and surgeons of head and neck have to know the exactly position of IOF (Hollinshead; Dubrul; Figun & Garino), because the anesthetic must be put on the foramen in order that it diffuses by the canal and causes the anterior superior alveolar nerve block (that appears on the infraorbital canal of 6,0 to 10,0mm before the infraorbital nerve emerges on the foramen), and in consequence, the block of the branches (which proceed of that nerve) that supply the central superior incisive teeth, lateral incisive and superior canine, ipsilateral to the blocked nerve (Zide & Swift).
