Alveolar Bone
Alveolar Bone
The part of the periodontium that supports and surrounds the teeth. It is present only where teeth exist and forms in response to their presence.
Periodontium
Periodontium
The tissues that surround and support the teeth, including the gingiva, periodontal ligament, cementum, and alveolar bone.
Periodontal Ligament
Periodontal Ligament
Connective tissue attaching tooth / cementum to the alveolar bone.

Study Notes
- The aim is to outline the clinical and radiographic anatomy of alveolar bone.
- Identify the structure and function of alveolar bone.
- Identify features of alveolar bone from healthy to disease.
- Recognise the relevance of radiographic assessment in periodontal disease.
Periodontium Components
- Gingiva
- Periodontal ligament
- Cementum
- Alveolar Bone
Development of Alveolar Bone
- AM: ameloblasts
- BO: alveolar bone
- DE: dentin
- DP: dental pulp
- DF: dental follicle
- ED: embryonic day
- EN: enamel
- OD: odontoblasts
Alveolar Bone Structure
- Exists only where teeth are present.
- It forms in relation to teeth.
- Structurally similar to and continuous with basal bone.
- It is subjected to continuous and rapid remodeling from tooth eruption and mastication.
Alveolar Bone Function
- It provides support.
- Offers protection for the teeth.
- Facilitates attachment via Sharpey's fibres.
- Acts as a shock absorber.
Healthy Alveolar Bone
- The height of the Cemento-Enamel Junction (CEJ) to the alveolar bone crest is 1-2mm.
Defect: Dehiscence
- Risk factors of gingival recession can be found online, definition: https://pocketdentistry.com/9-mucogingival-grafting-procedures-an-overview/
Age Changes
- Osteoporosis leads to bone loss and low density.
- Brittleness occurs because of decreased water content.
- Sponge bone becomes thin trabecular with wide marrow spaces.
Radiographic features
- Alveolar bone crest / Alveolar crest
- Lamina dura
- Periodontal ligament space
- Cancellous bone / Spongy bone
Radiographic Relevance
- Alveolar bone crest height helps to classify the severity of Periodontitis.
