Study Notes
Alveolar Bone Anatomy
- Alveolar bone, crucial for dental support, is a specialized bone structure.
- It surrounds the tooth roots, forming a socket (alveolus).
- Consists of different parts:
- Alveoli (sockets)
- Inner (lingual) alveolar plate
- Interradicular septum
- Interdental septum
- Outer (buccal) alveolar plate
Histological Structures of Alveolar Bone
- Cementum: Covers the tooth root.
- Alveolar bone: Forms the tooth socket.
- Periodontal ligament: Connects tooth to alveolar bone.
- Gingiva: Tissue encompassing the bone.
Bone Types in Alveolar Bone
- Compact bone: Dense and hard outer layer.
- Cancellous (spongy) bone: Inner, less dense portion.
- Alveolar plate (Outer, Buccal Alveolar plate): Form the tooth socket walls
- Cribriform Plate: A porous bone structure involved in forming the inner wall of the alveolus.
- Alveolar Crest: The superiormost edge of alveolar bone.
