Blood supply to the periodontium


Vessels of periodontal anastomose (together)to create a comprehensive system of blood vessels that supply blood to the tissues of parodentium.

This network of blood vessels acts as a unit, supplying blood to the soft and solid tissues of the upper jaw and lower jaw. This distribution of this rich blood supply gums, account for the dramatic color changes that are visible in gingivitis.

The basic functions of a complex network of blood vessels periodontium is to transport oxygen and nutrients to the cells of periodontal tissue and remove carbon dioxide and other waste products from the cells for liquidation. Vascular supply of periodontal tissues (Fig. 1-23)

Blood supply of periodontal ligament

Maxillary gums, periodontal ligament and alveolar bone

  1. Front and rear head of the alveolar arteries
  2. Infraorbital artery
  3. More Palatine artery
Lower alveolar artery.
A branch of the lower alveolar artery: the buccal, persons, mental, and sublingual arteries. The blood supply of teeth and periodontal tissues. Superior alveolar arteries-jaw of periodontal tissues. Lower alveolar artery temporomandibular of periodontal tissues. Branch of the arteries (Fig. 1-24 1-25 and)

Vascular supply of periodontal ligament

  1. Dental artery: the branches of the upper or lower alveolar artery
  2. Intraseptal artery: a member of the tooth socket
  3. Rami perforating: terminal branches intraseptal artery; they penetrate the tooth socket and enter the periodontal ligament space, where they anastomose (join) with vessels from the alveolar bone and periodontal ligament
  4. Supraperiosteal blood vessels: located in the free gum and are the main reserve of blood for free gum; these vessels anastomose with blood vessels from the alveolar bone and periodontal ligament
  5. Subepithelial plexus: branches supraperiosteal blood vessels located in the connective tissue under a free and attached gingiva
  6. Periodontal ligament, vessels: delivery of the periodontal ligament and form a complex network of blood vessels that surrounds root
  7. Periodontal plexus: fine network of blood vessels located in the connective tissue under the gingival sulcus
