inferior alveolar nerve

The inferior alveolar nerve is an important branch of the mandibular branch of the trigeminal nerve. It

mainly innervates the mandibular teeth, periodontal ligament, gingiva, skin and mucosa of the lower lip and chin. This makes the inferior alveolar nerve play a key role in sensory conduction in these parts. In many oral and maxillofacial surgery, such as wisdom tooth extraction, special attention should be paid to protecting the inferior alveolar nerve. If the surgical operation is improper, it may lead to complications such as postoperative numbness of the lower lip and affect the patient's quality of life.

When the inferior alveolar nerve is affected by inflammation, tumor and other factors, pain and numbness in the corresponding area will appear, which is important for the diagnosis and treatment of related diseases.
