Anterior superior alveolar artery

Anterior Superior Alveolar Artery

The Anterior Superior Alveolar Artery (ASAA) is a branch of the Maxillary Artery that supplies blood to the upper front teeth and the maxillary sinus. It is a significant artery in the Oral and Maxillofacial Anatomy.

Anatomy

The Anterior Superior Alveolar Artery originates from the infraorbital part of the maxillary artery, which is a branch of the External Carotid Artery. It descends in the infraorbital canal along with the Infraorbital Nerve, giving off several branches to the upper anterior teeth and their associated periodontal structures.

Function

The primary function of the Anterior Superior Alveolar Artery is to supply oxygenated blood to the upper anterior teeth, including the central incisors, lateral incisors, and canines. It also provides blood supply to the maxillary sinus and the associated periodontal structures.

Clinical Significance

Knowledge of the Anterior Superior Alveolar Artery is crucial in various dental procedures, including dental implant placement, root canal treatment, and maxillary sinus augmentation. Damage to this artery during such procedures can lead to complications such as bleeding, hematoma formation, and inadequate blood supply to the treated area.
