Alveolar Branches Maxillary Anterior

The alveolar branches of the maxillary anterior (rami alveolares maxillares anteriores) are branches of the maxillary artery that extend from it in the area of ​​the anterior teeth of the upper jaw.

These branches run within the alveolar process of the maxilla and provide blood supply to the anterior teeth and gums in this area. They are the terminal branches of the maxillary artery, have no further branches and end in the gum tissue.

The number of alveolar branches of the maxillary anteriors varies from 2 to 5 on each side. They arise from the maxillary artery at an acute angle, pass between the roots of the teeth of the upper jaw and branch inside the alveoli, forming anastomoses with branches going to neighboring teeth. Their diameter is usually 0.2-0.5 mm.

Thus, the alveolar branches of the maxillary anterior play an important role in the blood supply to the anterior parts of the upper jaw and teeth. Damage to these vessels can lead to the development of ischemia and tissue necrosis in this area.

The alveolar branch of the maxillary anterior (ramus alveolaris maxillaris anterior, RAMA) is a branch of the maxillary nerve that emerges from the posterior wall of the maxillary sinus and passes through the anterior alveolar arch to the alveolar arch. It bears branches to the front teeth of the upper jaw, including molars, premolars and incisors.

The alveolar branch of the maxillary anterior begins from the posterior end of the maxillary foramen, which is located on the lateral wall of the middle cranial fossa. It then passes through the maxillary sinus and exits through the anterior opening of the maxillary bone. After this, it passes through the alveolar canal, which is located in the anterior alveolar arch.

One of the main functions of the alveolar branches of the maxillary anteriors is to provide innervation to the anterior teeth of the upper jaw. They also bear branches to other oral structures such as the gums, tongue, and palate.

If the alveolar canal or its branches are damaged, pain in the teeth or gums may occur, as well as disturbances in sensitivity and taste. Treatment of such injuries may include surgery aimed at restoring normal blood supply and innervation to tissues.

Thus, the alveolar branch of the maxillary anterior plays an important role in the innervation and blood supply of the anterior teeth of the upper jaw and other structures of the oral cavity. Understanding its anatomy and function can help in the diagnosis and treatment of diseases associated with this branch.
