The buccal nerve (long buccal nerve) is a sensory nerve of the face arising from the mandibular nerve (CN V3) (which is itself a branch of the trigeminal nerve). It conveys sensory information from the skin of the cheek, and parts of the oral mucosa, periodontium, and gingiva.
The buccal branches of the facial nerve (infraorbital branches), are of larger size than the rest of the branches, pass horizontally forward to be distributed below the orbit and around the mouth. Branches
The mandibular nerve immediately passes between tensor veli palatini, which is medial, and lateral pterygoid, which is lateral, and gives off a meningeal branch (nervus spinosus) and the nerve to medial pterygoid from its medial side. The nerve then divides into a small anterior division and a large posterior division.
The lingual branch of the mandibular division (V3) of the trigeminal nerve supplies non-taste sensation (pressure, heat, texture) to the anterior part of the tongue via general somatic afferent fibers. Nerve fibers for taste are supplied by the chorda tympani branch of the facial nerve via special visceral afferent fibers. [10]
The risk of nerve injury in relation to mandibular dental implants is not known but it is a recognised risk requiring the patient to be warned. [10] If an injury occurs urgent treatment is required. The risk nerve injury in relation deep dental injections has a risk of injury in approximately 1:14,000 with 25% of these remaining persistent.
The mental nerve is a branch of the posterior trunk of the inferior alveolar nerve. This is a branch of the mandibular nerve (CN V 3), itself a branch of the trigeminal nerve (CN V). [1] It emerges from the mental foramen in the mandible. [2] It divides into three branches beneath the depressor anguli oris muscle.

There are usually two deep temporal nerves - the anterior deep temporal nerve and posterior deep temporal nerve. Occasionally, a third one is present - the middle deep temporal nerve. [2] Origin. The anterior one may arise from the buccal nerve, and the posterior one may arise from the masseteric nerve. [2]
