    Study Notes

    Alveolar Bone

    • Alveolar bone is the same as the alveolar process.
    • It is located in the jaw and supports teeth.
    • It is only present where teeth are present.
    • Alveolar bone forms in relation to teeth.
    • Alveolar bone is thinner on the buccal side compared to the palatal side.
    • The alveolar process is structurally similar and continuous with the basal bone.
    • The alveolar bone is thicker in the posterior region of the jaw to support the molars for mastication.
    • Bone resorption can occur due to periodontal disease or trauma.

    Radiographic Features of Alveolar Bone

    • The alveolar crest is the point of the alveolar bone where it meets the tooth.
    • Lamina dura is the compact bone that surrounds the tooth root.
    • The periodontal ligament space is the dark space between the tooth root and the lamina dura.
    • Cancellous bone is the spongy bone found within the alveolar bone.

    Radiographic features of alveolar bone in a healthy state

    • The alveolar crest is approximately 1–2 mm in height from the cemento-enamel junction (CEJ).
    • The periodontal ligament space is narrow and defined.

    Radiographic features of alveolar bone in a diseased state

    • Bone loss appears darker on the radiograph.
    • The distance between the CEJ and the alveolar crest increases as bone is lost.
    • The periodontal ligament space appears wider.
    • Calculus spurs may be present.
    • Loss of bone in the furcation region may be observed.

    Radiographic relevance of alveolar bone crest height in periodontal classification

    • Classification guidelines rely on radiographs to assess the amount of bone loss.
    • Bone loss percentage and patient age can be used to understand the progression of periodontal disease.

    Summary

    • Understanding the structure, function, and radiographic appearance of alveolar bone is crucial for diagnosing periodontal disease.
    • This knowledge is essential for maintaining the foundation of dental health.
