Lower Alveolar Nerve Block Anesthetic Needle Entry Point

The entry point of inferior alveolar nerve block anesthesia is the midpoint of the connection between the upper and lower posterior teeth and the lateral part of the pterygomandibular fold, which is the entry point in the case of open mouth. And the tip of the buccal fat pad on the buccal side, the point toward the pharynx is the point of entry. When the doctor enters the needle, the syringe should be placed on the opposite side of the bicuspid area, and then from the point of entry into the needle. After entering the needle and touching the bone surface, draw back for blood. If there is blood, the needle can be retracted into the submucosa, changed direction, and inserted again. If there is no blood, the drug can be injected directly, and the effect of anesthesia after the injection of the lower tooth nerve block will appear, and then the tooth can be extracted.
