What does the IA injection numb?

Purpose of an Inferior Alveolar Nerve Block Injection An IANB completely numbs one side of your lower jaw, including the teeth, gums, chin, lower lip, and, in some instances, the tongue.

What happens if inferior alveolar nerve is damaged?

There is a range of common inferior alveolar nerve damage symptoms, regardless of how the IAN is damaged. A damaged IAN will reveal itself through pain or abnormal sensations in the chin, lower teeth, lower jaw, and lower lips. Nerve damage may result in speech difficulties and/or affect chewing.

What is the ID canal?

In human anatomy, the mandibular canal is a canal within the mandible that contains the inferior alveolar nerve, inferior alveolar artery, and inferior alveolar vein.

How long does it take for inferior alveolar nerve to heal?

In most cases, complete recovery occurs 6 to 8 weeks after the trauma, although it may take up to 24 months.

What does inferior alveolar nerve supply?

The inferior alveolar nerve supplies feeling to your lower teeth. It’s a branch of the mandibular nerve, which itself branches off from the trigeminal nerve. It’s sometimes called the inferior dental nerve.

What causes inferior alveolar nerve?

Introduction. Causes of inferior alveolar nerve (IAN) injury include local anesthetic injections, third molar surgery (TMS), implants, endodontics, ablative surgery, trauma, and orthognathic surgery.

What is the alveolar nerve?

The superior alveolar nerves are all branches of the maxillary nerve, which is the second branch of the trigeminal nerve. The inferior alveolar nerve, which is small in length, is a branch of the mandibular nerve, which is the third branch of the trigeminal nerve.

What nerve is in mandibular canal?

The inferior alveolar nerve is located within the mandibular canal; therefore, to block this nerve it must be accessed before it enters the body of the mandible. The site at which the nerve is accessible is just before it enters the inferior alveolar foramen on the medial side of the ramus of the mandible.
