Alveolar Process and Basal Bone Anatomy

Alveolar Bone and Process

• Type I spongiosa is not commonly found in the maxilla.
• The increase in radiopacity of the alveolar bone is caused by compact bone formation.
• The main bulk of the alveolar septa is formed by the spongiosa.
• In some cases, the alveolar bone is composed of compact bone and marrow spaces.
• Type I spongiosa is anatomically characterized by a small number of thick trabeculae.
• The main function of the alveolar process is to support the teeth.
• The alveolar process is closely related to the basal bone, with the two being continuous.
• The facial and lingual surfaces of the alveolar process are separated by the cortical plates.
• The alveolar process consists of the alveolar bone, cortical plates, and spongiosa.
• The alveolar bone and cortical plates merge at the cervical third of the tooth root.
• The remaining bony part of the mandible or maxilla is referred to as the basal bone.
• The presence of the alveolar process is mainly determined by the presence of teeth.
• The facial and lingual surfaces of the alveolar process are separated by the cortical plates.
• The alveolar process crest is composed of compact bone and is located at the cemento-enamel junction (CEJ).
• The lingual plate of the cortical plates in lower posterior teeth is anatomically characterized by a thicker and more curved shape.
• The alveolar bone is histologically composed of compact bone and marrow spaces.
• Type II spongiosa is anatomically characterized by a large number of thin trabeculae.
• The cortical plate appears radiographically as a radiopaque line.
• The anatomical feature that causes the spongiosa to form the main bulk of the alveolar septa is the presence of marrow spaces.
• The increase in radiopacity of the alveolar bone is caused by compact bone formation.
