NERVE SUPPLY / INNERVATION OF MAXILLA AND MANDIBLE

Summary

The script outlines the detailed nerve supply to the mandible and maxilla, including various branches of the trigeminal nerve. It describes how the mandibular nerve supplies the lower jaw, with the inferior alveolar nerve serving the posterior teeth and incisive nerve supplying the anterior teeth. Other branches such as the mental nerve, lingual nerve, and buccal nerve provide sensory input to the gingiva, tongue, and the floor of the mouth. The maxilla’s nerve supply is detailed, with the anterior and posterior superior alveolar nerves innervating the upper teeth, while the palatine and nasopalatine nerves supply parts of the hard palate.

Takeaways

• 😀 The mandible is supplied by the mandibular nerve, which is a branch of the trigeminal nerve.
• 😀 The inferior alveolar nerve supplies the posterior teeth and the investing structures of the posterior teeth.
• 😀 The incisive nerve supplies the pulp and investing structures of the anterior teeth.
• 😀 The buccal and lingual gingiva of both the premolars and anterior teeth are supplied by the mental nerve.
• 😀 The buccal nerve supplies the buccal gingiva of the posterior teeth.
• 😀 The lingual nerve supplies the lingual gingiva, the floor of the mouth, and 2/3 of the tongue.
• 😀 The anterior teeth are supplied by the anterior superior alveolar nerve.
• 😀 The middle superior alveolar nerve supplies the premolars and the mesial part of the molars.
• 😀 The posterior superior alveolar nerve supplies the posterior teeth, except for the mesial part of the first molar.
• 😀 The anterior part of the hard palate is supplied by the nasopalatine nerve, while the posterior part is supplied by the palatine nerve.

Q & A

What is the source of the mandible's nerve supply?

What does the buccal nerve supply?

The buccal nerve supplies the buccal gingiva of the posterior teeth.

Which areas are supplied by the lingual nerve?

The lingual nerve supplies the lingual gingiva, the floor of the mouth, and two-thirds of the tongue.

What does the anterior superior alveolar nerve supply?

The anterior superior alveolar nerve supplies the anterior teeth.

Which teeth are supplied by the middle superior alveolar nerve?

The middle superior alveolar nerve supplies the premolars and the mesial part of the molar.

What is supplied by the posterior superior alveolar nerve?
