Superior Alveolar Artery

Superior Alveolar Artery and its branches.

The Superior Alveolar Artery is a branch of the Maxillary Artery that supplies blood to the upper teeth and gums. It is divided into three branches: the anterior, middle, and posterior superior alveolar arteries.

Structure

The Superior Alveolar Artery originates from the Maxillary Artery, which is a branch of the External Carotid Artery. It travels through the Infratemporal Fossa and enters the maxilla to supply the upper teeth and gums.

Branches

The Superior Alveolar Artery is divided into three branches:

• Anterior Superior Alveolar Artery: This branch supplies the incisors and canines.
• Middle Superior Alveolar Artery: This branch supplies the premolars.
• Posterior Superior Alveolar Artery: This branch supplies the molars and the sinus.

Function

The main function of the Superior Alveolar Artery is to supply blood to the upper teeth and gums. It also supplies the Maxillary Sinus and the Periodontal Ligament.

Clinical Significance

Damage to the Superior Alveolar Artery can lead to Hemorrhage during dental procedures. It can also cause Ischemia in the teeth and gums, leading to tooth decay and gum disease.
