Where is the buccal nerve located?
cheek
The BN, commonly referred to as the long buccal nerve by dental clinicians, is a sensory nerve that emerges between the two heads of the lateral pterygoid muscle and then descends toward the cheek along the tendon of the temporalis muscle.
What are the 3 Nerve blocks for the mandibular teeth?
There are 3 main approaches to achieving anaesthesia in the mandible: the inferior alveolar nerve block, also known as standard mandibular block or the Halstead approach; the Gow-Gates technique; and the Vazirani-Akinosi closed mouth block.
What is the insertion depth for a buccal nerve block?
The most effective position of the needle for administration of the V2 block injection generally is such that a 45-degree angle exists between the needle and the soft tissue. The needle is inserted to a depth of approximately 30 mm.
When do you give a long buccal nerve block?
A buccal block (of the long buccal nerve) is often done as part of the inferior alveolar nerve block procedure, if anesthetization of the lateral (buccal) gingiva and mucosa of the lower molars and second premolar is needed.
Are there two buccal nerves?
There are two branches of the nerve—superficial and deep. The superficial branches end in the cheeks and supply sensation to the skin of the cheeks, while the deep branches supply sensation to the lining of the cheeks and gums near the molar areas.
What is a buccal nerve?
Introduction. The buccal nerve is the only sensory branch of the anterior mandibular division of the trigeminal nerve. It innervates the major part of the buccal mucosa, the inferior buccal gingiva in the molar area, and the skin above the anterior part of the buccinator muscle.
How many buccal nerves are there?
two
The buccal nerve starts at the deep corners of the mouth, passes between the two heads of the lateral pterygoid muscle which control jaw movements, and spreads to the cheeks. There are two branches of the nerve—superficial and deep.
What is a long buccal nerve?
The BN (also referred to as the long buccal nerve) is typically described in anatomy textbooks7-9 and anatomical studies10-12 as a sensory branch of the mandibular division of the trigeminal nerve that innervates the entire mucosa of the cheek, as well as the skin around the angle of the mouth.
Where is the Coronoid notch?
The coronoid notch (retromolar fossa) is the concavity of the anterior edge of the ramus, located posterior to the molars. The pterygomandibular triangle is a fatty space bordered laterally by the coronoid notch, and medially by the pterygomandibular raphe.
What nerves does the Gow Gates anesthetize?
The Gow-Gates anesthetizes the inferior alveolar and its terminal branches (incisive and mental), lingual, mylohyoid, auriculotemporal, and the buccal nerve 75% of the time.
What muscle does buccal nerve supply?
The buccal nerve divides off the anterior division and passes with the paired nerves to lateral pterygoid between the two heads of the lateral pterygoid muscle. It descends deep to temporalis muscle, between it and the inferior head of the lateral pterygoid muscle.
