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.
