This document summarizes the key aspects of alveolar bone, including its definition, functions, structure, and age-related changes. Alveolar bone houses tooth roots through Sharpey's fibers, supports tooth eruption, and distributes occlusal forces. It has an inner bundle bone layer and outer supporting bone with cortical plates and spongy bone. With age, alveolar bone experiences loss, increased marrow spaces, osteoporosis, and maxillary sinus enlargement resulting in less support and increased brittleness.

3. DEFINITION
Alveolar process is that part of
maxilla and mandible that
contains the alveoli or sockets of
the teeth and supports the
teeth.

4. FUNCTIONS
I. Houses the tooth roots to alveoli by
insertion of Sharpeys fibers.
II. Organizes eruption of primary and
permanent teeth.
III. Contributes to absorption and
distribution of occlusal forces.
IV. Supplies vessels to the periodontal
ligament.

7. ALVEOLAR BONE PROPER
Bundle Bone
Thin layer in the inner socket wall that
surrounds the root and gives
attachment to principle PDL fibers.
Seen as LAMINA DURA in radiographs
Lamellated Bone
HISTOLOGICALLY ,consists of ;

9. SUPPORTING ALVEOLAR BONE
‘’ Cancellous trabeculae that
surrounds alveolar bone
proper to socket and support
the alveolus ”
It consists of 2 parts;
CORTICAL PLATES
SPONGY BONE

10. SPONGY BONE
“Bone which fills the space between
outer and inner plates and alveolar
bone proper’’.
Contain heavy trabeculae and bone
marrow space
TYPES:
Type 1
Present in mandible.
Type 2
Present in maxilla.

11. CORTICAL PLATE
• Made up of compact bone and
forms inner and outer plates of
alveolar process.
• Thinner in maxilla.
• Thicker mandible premolar and
molar
• Buccal thinner.
• No spongy bone in anterior teeth.

12. AGE CHANGES IN ALVEOLAR BONE
• Alveolar bone loss
• Marrow spaces increase
• Osteoporosis
• Maxillary sinus size increases
• Brittleness

13. • With time and wear,proximal contact
flattened.
• Mesial migration.
• Loss of arch length.
CLINICAL CONSIDERATIONS

14. CONCUSION
Mercury is the closest planet to
the Sun and the smallest one
in the Solar System—it’s only a
bit larger than the Moon
Despite being red, Mars is
actually a cold place. It’s full of
iron oxide dust, which gives
the planet its reddish cast

Saturn is the ringed
one and a gas giant
