Extraoral Inferior Alveolar Nerve Block Technique (Kurt Thoma Technique)

Extraoral Inferior alveolar nerve block (IANB) is a technique used to produce anesthesia of the mandibular teeth, gingiva of the mandible, and the lower lip. These procedures anesthetize the Extraoral Inferior alveolar nerve (IAN) prior to entering the mandibular foramen. The inferior alveolar nerves supply sensation to the lower teeth, and, via the mental nerve, sensation to the chin and lower lip. The mylohyoid nerve is a motor nerve supplying the mylohyoid and the anterior belly of the digastric.

Inferior alveolar nerve block (abbreviated to IANB, and also termed inferior alveolar nerve anesthesia or inferior dental blockis a nerve block technique. Provide sensory innervation to all of the upper teeth in the maxilla as well as the gingiva. The numbing sensation typically lasts 30 to 60 minutes. Since Novocaine by itself has a very short duration of action.

The bottom row of teeth receives sensory branches from the nerve. In edentulous patients, the measurement is from the alveolar ridge of the edentulous maxilla/mandible incisor to the opposing side. For example, nerve blocks for hand surgery usually last for 6-8 hours, but a nerve block for pain after total knee replacement can last for 12-24 hours. Medication continuously delivered through a tiny plastic tube (nerve catheter) placed next to the nerve can last for 2-3 days.
