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.
