The inferior alveolar arteries are responsible for the direct perfusion of the lower jaw and the lower jaw’s structures. The branches that arise from the inferior alveolar artery will travel with the corresponding nerve to perfuse the same structure as the nerve innervation.
What are the branches of inferior alveolar artery?
It runs along the mandibular canal in the substance of the bone, accompanied by the nerve, and opposite the first premolar tooth divides into two branches, incisor and mental. Near its origin the inferior alveolar artery gives off a lingual branch then, enters the foramen, it gives off a mylohyoid branch.
What is the course of the inferior alveolar artery?
The inferior alveolar artery is a branch of the maxillary artery. It runs with the inferior alveolar nerve as it descends through the infratemporal fossa and enters the mandibular canal and supplies mandibular teeth.
What is the inferior alveolar nerve a branch of?
mandibular
While the inferior alveolar nerve originates from the mandibular branch of the trigeminal nerve, the alveolar nerve will branch into the mental nerve. All of these alveolar nerves and their subdivisions will contribute to sensory innervation to the face and mouth.
What are the branches of the inferior alveolar artery and what teeth does each supply?
The inferior alveolar artery is a branch of the maxillary artery. It runs with the inferior alveolar nerve as it descends through the infratemporal fossa and enters the mandibular canal and supplies mandibular teeth. In the region of the first premolar it bifurcates into the incisive and mental branches.
How do you give an inferior alveolar injection?
Block the buccal nerve Withdraw the syringe and reinsert it just anterior and lateral to the anterior edge of the ramus at the level of the occlusal surface of the most posterior molar. Advance the needle posteriorly about 3 to 5 mm. Aspirate, to rule out intravascular placement, and inject about 0.25 mL of anesthetic.
Why is it called inferior alveolar nerve?
The inferior alveolar nerve (sometimes called the inferior dental nerve) is a branch of the mandibular nerve, which is itself the third branch of the trigeminal nerve….
| Inferior alveolar nerve | |

| To | mylohyoid, dental, incisive, and mental |
| Innervates | dental alveolus |

| Latin | nervus alveolaris inferior |
Where is inferior alveolar nerve located?
The inferior alveolar nerve or inferior dental nerve is a mixed sensory and motor branch of the posterior division of the mandibular division of the trigeminal nerve, located in the pteryogomandibular space of the oral cavity/masticator space.
What is the purpose of the alveolar process?
The alveolar process is the thick ridge of bone in the jaw that holds the dental alveoli, or tooth sockets. The dental alveoli hold the roots of the teeth in place, and in case of a dental implant, the alveolar process holds implant hardware in place.
What is the function of the inferior alveolar artery?
The inferior alveolar artery and its incisor branch during their course through the substance of the bone give off a few twigs which are lost in the cancellous tissue, and a series of branches which correspond in number to the roots of the teeth: these enter the minute apertures at the extremities of the roots, and supply the pulp of the teeth.
What is a preparatory ligation of arteries?
3. Ligation of arteries Severe arterial hemorrhages during major operations can often be prevented by a preparatory ligation of the respective artery. The numerous and wide anastomoses of all facial arteries with one another and with the contra lateral arteries often make bilateral ligation necessary.
What happens when you have an inferior alveolar nerve block?
An inferior alveolar nerve block is one of the most commonly performed dental procedures. 3 The result is numbness in the lower teeth, chin, and lower lip. In some cases, the tongue will lose sensation as well because the lingual nerve, which innervates the tongue, sits near the inferior alveolar.
What is the mylohyoid branch of the alveolar artery?
Mylohyoid branch. As the inferior alveolar artery enters the foramen, it gives off a mylohyoid branch which runs in the mylohyoid groove, and supplies the mylohyoid muscle .
